800 SeriesHydraulic Control Valves

800 serieshydraulic control valves

general definition Armaş 800 series automatic hydraulic control valves are designed in the “Y” body model type so as to show maximum resistance to cavitation under minimum head loss in high flow rates.

Armaş 800 series automatic hydraulic control valves are double-chamber diaphragm actuated and disc closed type. Valve has a standard double control chamber. However, if required, it maybe used as a single control valve without using an extra control chamber. In addition, if required, the valve operates easily controlledly even in very low flows by means of an extra port added to the disc. Valves performing various functions may be obtained by adding different control equipment to the basic valve body.

advantages & benefits • The “Y” type valve body designed hydrodynamically provides 25 % more flow compared to standard globe bodies and has a lower head loss. •Double-chamber diaphragm actuator provides quicker and non-impact opening/closing thanks to disc-closing valve design compared to diaphragm-actuator, diaphragm-closing valves and prevents blockage by showing less sensitivity against solid substances within fluid. •Ensures maximum flow thanks to its “Y”- type body. •Is effected minimally from cavitation damages thanks to its broad “Y”- type body design. •Has easy use and maintenance due to simple design. •Makes opening and closing without causing and surges. •Ensures smooth control thanks to its standard dual control chambers. •Provides full tightness thanks to its stem bedded rigidly and stainless steel spring. • It operates controlledly and smoothly and closes hermetically by means of valve stem embedded rigidly on valve body. • Closing disc provides tightness by means of elastic rubber in the disc, sitting in the replaceable body bush. •Does not require maintenance in operation for a long time due to its corrosion resistant components. •Has a long working life in operation since coating has been made with phosphorization and over-dried epoxy powder paint. •Performs perfect modulation in variable flows and even too low flow rates close to zero. •Has a wide range of application with use of different pilot valves.

Using With Single/Double Chamber Actuator

Using with single chamber actuator

Using with double chamber actuator

Armaş 800 series automatic hydraulic control valves are designed with double-chamber actuator as a standard. Valve can be easily used with single or double-chamber actuator without need for any additional parts.

When using the valve with single-chamber actuator, the plugs under the middle bonnet are removed and a plug is in started into the middle bonnet inlet port and thus, the valve actuator is made with single chamber. In such a case, the pressures to be compared are P1, P2, P3.

When using the valve with double-chamber actuator, the port holes under the middle bonnet for an extra P4 comparison pressure are closed with plugs and the P4 comparison pressure is given through the middle bonnet port. With P4 comparison pressure, valve controls may be further arranged with the aid of an extra pressure.

valve closing mode The control valve ensure that the valve closes hermetically with the valve disc’s sitting on the body bush by means of the force imposed by the inlet pressure on the diaphragm in the actuator by the pilot valve. When examining the forces on the valve with the aid of impact pressures and impact areas causing the valve to close, the following inequality will be obtained: P3x3A + Pspring > P1xAWith the pilot valve or manual intervention causing the valve to close, without hydraulic intervention in the section shown with P3 pressure out of installations, P3 pressure will be equal to the maximum P1 pressure. The force P3x3A + Pspring will prevail over the force P1xA. Thus, the inequality in proved including the force Pspring and the valve closes hermetically with the force obtained. The geometric properties of the Armaş 800 series automatic hydraulic control valves determined at the design level and the pressure P3 are not affected by pressure losses due to pilot valve and head losses in hydraulic systems thanks to the impact area ratio and the valve closes hermetically.

valve opening mode The force imposed by the inlet pressure trying to open the control valve, under the valve disc, ensures that the valve opens with prevailing over the pressure force on the diaphragm by means of the spring force and the pilot valve assisting in closing operation. When examining the forces on the valve with the aid of impact pressures and impact areas causing the valve to open, the following inequality will be obtained:P1xA > Pspring + P3x3A With the pilot valve or manual intervention causing the valve to open, the section shown with pressure P3 in put in discharge mode. In this case, the P3 difference pressure opened to atmosphere will be 0 (zero) and when the force P1xA overcomes (the spring force) Pspring , the valve will open. The minimum opening pressure of the valve will be determined by Pspring , because of overcoming the minimum Pspring force to open the valve.

modulation modePilot valves connected to the main valve actuator ensure that the main valve operates in modulated mode. They ensure that it operates in modulated mode by continuously controlling the pressure of fluid in the main valve actuator according to the flow rate or pressure conditions required to be adjusted when examining the force equations in the valve modulation valve with the aid of impact pressures and impact areas, the equationP1xA + P2x3A = P3x3A + Pspring + P2xAis obtained. The pilot valve used in the modulation of the valve ensures the modulation of the valve and keeps force equation by regulating the pressures P3 ve P2.

preventing cavitation

cavitation chart

cavitationCavitation occurs in hydraulic control valves when they are not used under proper pressure values. When fluid passes through the closing area of the hydraulic valve, its value will increase due to extreme choking and its static pressure will drop under the evaporation pressure of the fluid. The fluid evaporates and steam bubbles occur in the fluid. Such steam bubbles explode in the outlet side of the valve under the downstream pressure. Such sudden expositions produce intensive shock waves and temperature increases. Extreme reduction in the valve causes water jets. Shock waves and water jets break particles from valve body material and cause the valve to be worn out, to be pierced and to decrease its life due to such a use. Cavitation causes also damage to installation and thus noise and vibration.

· Increase the downstream pressure if the system allows to do so. · If downstream pressure can not be handled, increase valve diameter and thus decrease water speed, if possible.·Increase the number of pressure decrease points using multiple valves or use multiple valves at the same point to decrease pressure. Besides, decrease the pressure proportionally including the ARMAŞ 800 series proportional pressure reducing control valve in the system at certain points.

For the purpose of using cavitation charts: · Determine the valve upstream pressure specified in the system on the charts. · Make the required downstream pressure intersect the determined downstream pressure.· Determine the cavitation condition of the valve based on 3 areas whose intersections are shown on the charts.

PRpressure reducingcontrol valve

description

installation

typical application

Armaş “PR” model pressure reducing control valve is the hydraulic control valve which reduces high upstream pressure value into desired lower pressure value by means of built-in pressure reducing pilot valves. Pressure reducer control valve controls downstream pressure value continuously and maintains it constant without being affected from flow rate and upstream pressure values. When no flow exists in the system, it is closer by itself automatically. When valve upstream pressure value decreases below adjusted downstream pressure value, it is opened fully by itself. Valve may be user in vertical and horizontal positions in the system.

•Valve nominal diameter must equal to or one size smaller than line diameter.. •Mount valve in direction of arrow indicated on it. •It is recommended that insulation valves (butterfly or gate valves etc.), air relief valve, quick pressure relief valve (QR) and strainer valves will be used in line-mounting of valve. •During pressure decrease, cavitation risk is dangerous for valve body. Adjust downstream pressure value by referring cavitation data or consult our technical service.

3- way selector valve In-line Finger Filter Plug

descriptionArmaş “PRD” model proportional pressure reducing control valves reduce high upstream pressure values and downstream pressure values at a rate of 1/3. Proportional pressure reducing control valves reduces the downstream pressure at about 1/3 without affecting from flow rate and upstream pressure values. When there is no flow in the system, valve closes itself hermetically. Proportional pressure reducing control valves do not equalize the upstream pressure value to the downstream pressure value. The valves should be placed in series in the pipeline, otherwise the system will not be balanced. If required, pilot valves can be added to proportional pressure reducers to change them easily to regulation valves.

installation• Clean the pipeline before installing the valve. • Make sure that valve is on a level with the pipeline while mounting it. • Mount valve in direction of arrow indicated on it. • Ensure enough space around the valve assembly for future maintenance and adjustments. • While connecting valve on pipeline, place gasket between valve flange and pipe flange to ensure sealing and tighten the bolts as crosswise. • It is recommended that insulation valves (butterfly or gate valves etc.), air relief valve and strainer valves will be used in line-mounting of valve.

description

installation

Armaş “PREL” model pressure reducing valve is the hydraulic control valve which reduces high upstream pressure value into desired lower pressure value. Control of main valve is achieved by means of built-in 3/2 -way solenoid pilot valves. Electric signal for solenoid pilot valves is ensured by means of a control device, time relay, main switch and PLC control units etc. Automated control may be easily ensured by this way in application systems.

• Connect cables of solenoid pilot valve in accordance with control device. • Make sure that valve is on a level with the pipeline while mounting it. • Mount valve in direction of arrow indicated on it. • It is recommended that insulation valves (butterfly or gate valves etc.), air relief valve, quick pressure relief valve (QR) and strainer valves will be used in line-mounting of valve (See sample montage illustration). • During pressure decrease, cavitation risk is dangerous for valve body. Adjust downstream pressure value by referring cavitation data or consult our technical service.

control valve FRflow rate

description

installation

typical application

Armaş “FR” model flow rate control valve is designed to limit desired flow rate. The orifice on main valve upstream creates pressure difference and 3/way differential pressure set pilot mounted in control chamber of valve senses this pressure difference and ensures that main valve opens in desired flow rate. Valve thereby limits desired flow rate automatically and keeps it fixed. It eliminates over flow by preventing excessive flow during reverse washing in filtration systems.

• Make sure that valve is on a level with the pipeline while mounting it. • Mount valve in direction of arrow indicated on it. • When orifice is connected to pipeline, mount in such a way that tightness between upstream flange and pipe flange will be ensured. • Mount hydraulic control lever of pilot valve before valve and orifice conveniently. • It is recommended that insulation valves (butterfly or gate valves etc.), air relief valve and strainer valves will be used in line-mounting of valve (see sample montage illustration).

Orifice plates provide a rough control of flow rates while differential pressure adjustment pilot valves provide an accurate control. Inner diameters of orifice plates are adjusted according to the flow rate properties of the system. Thus, when adjustment flow rates in flow rate control change greatly, the inner diameter of the orifice plate should be recalculated and resigned. In such a case, please contact our company with the present and changeable flow rate and valve diameter values.

typical application

Armaş “QR” model quick relief control valve is the safety control valve designed to protect system by releasing pressure surges to atmosphere quickly caused from sudden changes in water speed because pumps put into/out of service frequently in water network elevation lines. When network pressure goes beyond set point, valve opens by itself quickly and protects system by releasing over pressure. When line pressure decreases to normal level, it is closed slowly and automatically as wholly sealed without causing surge.

•Quick Pressure Relief control valve is mounted on network in TE configuration. •Since valve's function is to release pressure, valve diameter may be selected as equal to or in closest smaller size than main pipe diameter. Valve diameter should be selected as smaller than main pipe diameter. Following empirical formula may be used in determining diameter of quick pressure relief control valve. Where;

Valve closing time is proportional with pipe length. As system pipe length increases, valve closing time should be increased.

HCVhydraulic check valve

typical application

descriptionArmaş “HCV” model valve is hydraulically controlled check valve which operates with line pressure and prevents back-flow in system. When downstream pressure value exceeds upstream pressure value, valve is closed as wholly sealed without causing surge. When upstream pressure value exceeds downstream pressure value, check valve is opened by itself slowly. So it damps pressure surges formed during start-up.

installation•Clean the pipeline before installing the valve. •Make sure that valve is on a level with the pipeline while mounting it. •Mount valve in direction of arrow indicated on it. •Ensure enough space around the valve assembly for future maintenance and adjustments. •While connecting valve on pipeline, place gasket between valve flange and pipe flange to ensure sealing and tighten the bolts as crosswise. •It is recommended that insulation valves (butterfly or gate valves etc.), air relief valve and strainer valves will be used in line-mounting of valve.

adjustment• Operate pump, open main valve on network and deliver water to the system.

PCpump (booster)control valve

typical application

descriptionArmaş “PC” model pump control valve is a control valve designed for putting booster type pumps into/out of service automatically which is used water network elevating lines. When start button is pressed, pump control valve is opened by itself slowly in comparison with booster pump until pump rotation will reach working rotation. When “stop” button is pressed, control valve is closed slowly without causing surge in the first plan. When pump control valve was closed as fully sealed, it is disengaged from system by means of “Limit Switch” on it. In situations like energy interruption, works as a check valve to prevent back-flow to pump and eliminates use of an extra check valve in the system.

installation• Clean the pipeline before installing the valve. • Make sure that valve is on a level with the pipeline while mounting it. • Mount valve in direction of arrow indicated on it. • Ensure enough space around the valve assembly for future maintenance and adjustments. • While connecting valve on pipeline, place gasket between valve flange and pipe flange to ensure sealing and tighten the bolts as crosswise. • It is recommended that insulation valves (butterfly or gate valves etc.), air relief valve and strainer valves will be used in line-mounting of valve.

DPCdeep well (submersible) pumpcontrol valve

descriptionArmaş “DPC” model deep-well pump control valve is a relief control valve designed for putting deep-well type pumps into/out of service automatically. Valve is connected on main line with a “TE” piece. Valve is in open position before pump operates. When pump starts up, valve is closed by itself slowly without causing surge and increases system pressure gradually. Before pump stops, valve opens by itself slowly and automatically and decreases system pressure gradually.•Deep-well Pump control valve is mounted on network in TE configuration since it is a electric activated release valve. •Since valve's function is to release, valve diameter may not be selected as equal to or in closest smaller size than main pipe diameter. Valve diameter should be selected as smaller than main pipe diameter.
