Control valves are designed to stabilize pressure, level and flow in a given wa-ter system. The operation of this type of control valve can be hydraulic, elec-tric or electronic. There are also electric-hydraulic and electronic-hydrau-lic combinations available. In remote monitoring and control systems it is recommended to use electric or electronic systems with hydraulic redundancy.

Flucon 200 control valve is hydraulically operated, diaphragm actuated globe type val-ve. It consists of three major components: body, diaphragm assembly and cover. The diaphragm assembly containing the stem is fully guided at both ends. The diaphragm assembly is the only moving part and forms a sealed chamber separating the operation pressure from the line pressure.

This catalogue presents the most common models. If your application requires a diffe-rent solution please contact us, we will find a solution for your request.

Flucon 200

The pilot system is of modular type and the control pilots are in stainless steel 316L of “Integral Balanced Pressure” design, which means that a change in inlet pressure the system does not alter the pressure set point. The filter in the pilot system is high capacity (filtering area 50cm²) with body in stainless steel 316L and transparent bowl. The dirt is trapped on the outside of the screen and collects in the bowl. The collected dirt can be flushed directly out to drain by opening the ball valve. This drain valve may be equipped with solenoid control and electronic programmable timer.

Standard valves are supplied with opening - closing speed control OCS. If required the valves can be equipped with OSCS allowing independent opening and closing speed control. These controllers are also made of SS 316L All the non-stainless steel acces-sories are nickel plated as standard.

Note: Please see main valve materials and pilot system materials on pages 13 and 14.

There is a restriction orifice in the connection between the upstream section of pilot system and the control chamber, which will limit the flow rate that will cause the valve to open. Clearly, the valve will open, close or remain in the same position depending upon the decreasing or increasing of flow rate (pressure) in the control chamber. In order to make sure that the valve is able to close, the maximum flow rate allowed through the pilot is greater than the maximum flow rate allowed through the restriction orifice. Taking A as the wetted area on the surface of the plug, the diaphragm area is approximately 3A. Therefore the diaphragm area that is exposed to P2 at outlet of main valve is equal to 2A.

The on/off or modulating pilot controls the main valve by controlling the pressure P3

in control chamber. Disregarding the mass of the diaphragm assembly, the forces that will cause the valve diaphragm assembly to move are:

p1.A - Upstream pressure P1 applied on area A at the bottom of the disc.p2.2A - Downstream pressure P2 exerted on area 2A at the lower side of the diaphragmp3.3A - Upper chamber pressure P3A pushing down the diaphragm on area 3A.Fspring - Spring force

opening operationThe valve will open when the following condition is met:

P1.A + P2.2A > P3.3A + Fspring

closing operationIn the same way, if the valve is open, it will move towards closing when:

P1.A + P2.2A < P3.3A + Fspring

modulating operationIf the sum of the forces applied on the top side of the diaphragm is equal to the sum of the forces on the bottom side the valve plug will remain stationary, allowing a modulation regime: P1.A + P2.2A = P3.3A + Fspring

no Flow - no pressureIf there is no pressure is in the valve, the spring force and the weight of the diaphragm assembly hold the valve closed: P1 = P2 = P3 + Fspring + WDa (WDa - Diaphragm assembly weight, only for horizontally installed valves). Spring force will close the valve.

pressure control

pressure reducing - Flucon 200.02 Automatically reduces higher upstream pressure to lower downstream pressure regar-dless of fluctuations in inlet pressure and/or flow rate.

pressure reducing stabilizer - Flucon 200.02(e) Similar to Flucon 200.02 but with two pressure reducing pilots in series. Used when inlet pressure fluctuations are very large and to maintain a stable outlet pressure.

pressure reducing and sustaining - Flucon 200.02.03(s)Combines pressure reducing and pressure sustaining functions. Sustaining pressure permits the valve to open only when the upstream pressure exceeds the sustaining pilot set point. Should high demand cause the inlet pressure to fall to the sustaining pilot setting, the valve will modulate to prevent the upstream pressure from dropping below the set point.In gravitational water distribution systems this feature avoids the inflow of air into the pipeline.

pressure reducing intermittent low Flow - Flucon 200.02(lF)Similar to the Flucon 200.02, but incorporating a direct acting pressure reducing pilot installed in parallel, using the main valve back port connections. Under low flow con-ditions the main valve closes, and the by-pass opens, controlling the pressure at very low flows without seat chatter or noise.

pressure reducing - Flucon. 200.02.02.hDSimilar to the 200.02 but with two pressure reducing pilots installed in parallel and one solenoid pilot. The valve allows selection between two different pressure reducing set points and is suitable for pressure control applications that require different levels of pressure reduction at different periods of time.

electronic control of p2 or p1 - Flucon 200(Bu).el-pi.02 or 03(s)This is the right option to integrate a control valve in a SCADA system. The Flucon 200(BU). El-PI with a proportional analogue 4-20mA control pilot and a PI controller will provide the connection of the valve to a remote monitoring and control system. The controller has a display and the possibility of changing the set points locally and remotely. With this advanced type of control we can accurately position the control valve to continuously regulate P1 or P2. The system will automatically change from electronic mode to hydraulic mode in case of power failure.

important note - pressure sustainingIn gravitational water distribution systems it is recommended to include the optional pressure sustaining feature in all control valves. This way the pressure will be kept balanced at higher levels upstream. It will also prevent the inflow of air into the pipeline.

Fixed level Float control - Flucon 200.04(n)The float pilot closes or opens the main valve as the level in the reservoir reaches or drops from the float’s level, respectively. This way, the inflow to the reservoir balances with the outflow and the water level is kept nearly constant within close limits.

non modulating Float control - Flucon 200.04(Di) This model functions automatically to open wide when the level reaches a predetermi-ned low point (bottom float) and to shut drip tight when the high point is reached (top float). The valve remains as the level drops, until it reaches the bottom float at which time the valve opens to refill the tank. The on-off service ensures that the reservoir contents are cycled. The level differential is determined by the length of pipe that con-nects the two parts of the pilot (top and bottom floats).

solenoid control - Flucon 200.hD This model is commanded directly by an onoff electric level control device. The so-lenoid pilot provides two operation positions (on-off). The solenoid either admits the inlet pressure into the main valve operating chamber or releases pressure from the operating chamber. The pilot is usually piped to discharge to the atmosphere. This model is available either with the main valve normally closed (NC) or the main valve normally open (NO).

one Way Altitude control - Flucon 200.05(A)The valve closes precisely when the water level reaches the altitude pilot setting and opens when the level lowers below (10 cm) the shutoff level. This model is used on reservoirs where the water is withdrawn through a separate pipeline.

two Way Altitude control - Flucon 200.05(B)The valve closes when the water level reaches the pilot setting and opens for return flow when pressure at the main valve inlet is less than the storage reservoir’s pressure.

electronic level control - Flucon 200(Bu).el-pi.05 This is the best option for integration in a SCADA system. A Flucon 200(BU).EL-PI with a proportional analogue 4-20mA pilot and PI controller provides extreme facility in connection to supervision systems. The controller features a display, and local and remote setpoints. With this advanced type of control the reservoir can be filled to the required level accurately and continuously. This valve includes hydraulic redundancy, which means that the hydraulic pilot takes control in case of power failure.

important note - level controlIn gravitational water distribution systems it is recommended to include the optional pressure sustaining feature in all control valves. This way the pressure will be kept balanced at higher levels upstream. It will also prevent the inflow of air into the pipeline.

FloW control

Flow rate control - Flucon 200.06(oc)Limits the flow to a preset maximum. A Calibrated orifice generates low and high pressures for the differential pressure pilot. Can also be used when installed downs-tream of a pump, to control the differential pressure between the inlet and the outlet, preventing cavitation damage.

Velocity shut off - Flucon 200.06(oci)This valve is similar to 200.06(OC) but closes drip tight and remains closed if the flow exceeds the maximum setpoint. This is a dangerous application because fire protection systems are connected to the public water distribution network.

Flow control - Flucon 200(Bu).el-pi.06(oc).Dpt This model uses a differential pressure transmitter and a calibrated orifice plate. The output of the transmitter is connected to the electronic proportional pilot Flucon EL-PI. This is a normally closed valve.

metering, totalizing and Flow controlFlucon 200(Bu).el-pi.06(oc).emFThis model is similar to the Flucon 200. EL-PI.EMF but with a backup fail safe system. In case of power failure the hydraulic pilot takes control.

If a pumping system is not correctly designed it can result in serious damage and in-jury. We have the right solution for pump control equipment including the new Flucon 200.09.EL-PI which is an electronic surge antecipating and relief valve that protects against power failure surges or overpressure. Pump control valves are the right solu-tion to control your pump station. This catalogue presents the most common models.

Booster pump control - Flucon 200.07(Bp)Mounted downstream of a pump this type of valve will open and close slowly. It elimi-nates the transient pressure surges that are associated with the starting and stopping of pumps. The opening and closing speeds are independently adjustable. These valves also include a non-return feature that is activated in case of power failure (reverse flow).

pressure relief - Flucon 200.03(A)Mounted in a tee on the main pipeline downstream of a pump or pressure reducing station. Opens when inlet pressure exceeds a predetermined setting.

surge Anticipating & relief - Flucon 200.09Automatically opens to dissipate the excess energy of a pressure surge when a pump starts or stops. Opens quickly to relieve high pressure (relief function) and opens under low pressure to anticipate the return of a surge wave.

surge Anticipating electronic - Flucon 200.09.el-piAutomatically opens to dissipate the excess energy of a surge in starting and stopping a pump. Opens quickly to relieve high pressure (relief function) and opens under low pressure to anticipate the surge wave. This is an electronic valve and is supplied with a pressure transmitter, a controller and the valve is connected to a UPS.

other Flucon modelsIn certain situations, the pump control valves may incorporate a pressure sustaining system. This application is very useful, for example, when a pump delivers a head higher than the network requirements. In this case, the use of a pressure sustaining feature will prevent cavitation and will cause the pump to work within the range that is recommended by its manufacturer.

important note - pump controlThe outlet pipe of pressure relief and surge anticipating valves should be submerged in water, in order to prevent air from getting into the pipeline. This way, if vacuum is present in the main line, water will be sucked into the system instead of air. If the valves discharge to the atmosphere please make sure that the fluid exit is not directed in a way that may be liable to causing damage or injury. Remember that we are dealing with high pressures.

VAlVes selection

The information contained in this section should be regarded as a general guide for the selection of valves and network design.Please gather all the required parameters, in order to define the service conditions:

f Q - Volume flow rate (minimum, maximum and regular values); f p1- Upstream pressure; f p2- Downstream pressure; f pr- Target pressure; f Is the electrical valve normally open or normally closed? What are its voltage

and current. f Please use page 10 formulas and take into account the cavitation graph. f Remember to apply the safety factors, which are shown on the table at page 10.

If you need assistance please do not hesitate to contact us. Our team will analyse pour application and will present you the best solution.

Specify control valves for public water distribution systems full lift, full bore until DN80. Remember that fire fighting systems are connected to public water distribution network.

This is the reason why Flucon standard valves are full lift and full bore from DN50 to DN100.

For bigger diameters or high ∆P use the calculation formulas.

When a valve is correctly specified for continuous flow, verify if intermittent low flow happens for brief periods of time. As velocity increases between the seat and the plug the risk of cavitation increases. For this reason do not oversize valves. Use anti-cavitation trim, or parallel valves.

Flucon system - Booster pump control (Flucon 07(Bp)) + electronic surge anteci-

pating relief (Flucon 09.hD2)

Valve B in the figure below is a Flucon 200.07(BP), with local regulation of opening and closing

speed for better system performance. The Flucon 200.07(BP) also integrates an automatic closing

system, which is adjustable for protection against water column return.

Valve C is a normally open surge anticipating valve. The model is Flucon 200.EL-PI.09. The ope-

ning and closing commands are achieved with the use of a 24VDC electric impulse version pilot

(latch coil). The pilot is commanded by electric pulses, which only take place when changing the

valve state is required and that means power consumption is low.

The system includes an analogue pressure transmitter and a Flucon LS3300 PID controller.

The PLC programming keeps the valve closed between two predefined ranges. In case of power

failure, the water column will keep moving downstream towards a higher level for a short while.

When this happens pressure at the downstream of the pump decreases rapidly and when the pre-

defined level of low pressure is detected, the controller opens the valve in order to anticipate the

expected surge of high pressure. When gravity brings the water column back towards the pump

a high pressure wave is generated and the valve will open in order to relief the high pressure and

allow fluid to escape out of the pipeline. When the flow is reversed the pressure goes up sharply.

At this stage the valve is completely open and will channel out most of the pressure surge energy.

If the pressure again reaches the high preset level there will be a new opening command. This

process is repeated until all the energy of the pressure surge has dissipated. The Flucon LS3300

controller, the pressure transmitter and the Flucon valve are connected to a UPS.

Fluconjet h

FluconJet uses available hydraulic energy like a driving force. It is composed by a filtering set, a control set and an injection set, being completely autonomous without moving parts. It does not need power supply to work.

The set is composed by: f High capacity filter in stainless steel (50 cm2 filtering area); f Stainless steel pressure reducing pilot;

f Stainless steel control pilot

Working principle The regulation set, controls the driving pressure. The injector, in-ternal restrictor in venturi shape causes the increase in dynamic pressure and velocity, lowering the resulting pressure value. From this action results a low pressure area. This phenomenon will “suck” the chlorine. Besides the “Kinar” injector, this system may include an optional a micrometric valve and an acrylic rotameter as dosing indicator.

This model does not need auxiliary power supply, hydraulically guarantees the disin-fection of the water volume that goes into the reservoir. It was especially developed to use for water disinfection in isolated reservoirs graviticaly supplied in places where there is no power supply. It is installed with a differential float level control valve and flow limitation function – Flucon 200. 04(DI).06(DF).H2. When the minimum level is achieved (N2) the low level float depressurizes the pipe connection to the main valve, then the hydraulic pilot (A) opens and injects the disinfection product. When the maximum level is achieved (N1) the high level float closes the pipe connection to the main valve and the injection of chlorine stops. This system replaces the chlorine dosing pump.For correct function, minimum upstream pressure must be 0,5 bar.
