COMMON OPTIONSAs you will see, Parker offers a variety of PressureControl products. As such, some of the optionsmentioned below may not be available on all valves.Consult the model coding and dimensions for eachvalve for specifics. Here are some of the commonoptions available.
Adjustment Types: Parker offers four primary typesof adjustments for most of the pressure control pro-ducts. Samples of these types are shown below. Pleasenote all options may not be available for all valves.Consult the individual catalog pages for more details.
Screw Adjustment - Valve can beadjusted with an allen wrench. Locknut included to maintain desiredsetting after adjustment. This is themost common adjustment optionavailable on most Parker products.
Knob Adjustment - An aluminumknob is added to the standard screwadjustment. A lock knob is providedto help maintain the desired settingafter adjustment. Parker offers knobconversion kits for most pressurecontrol valves. For kit numbers consultindividual valve pages.
Fixed Style - In most cases, theFixed Style product is a screwadjustable product with a steel colletthreaded over the screw adjustment.These valves are preset at thefactory.
Tamper Resistant - The tamperresistant option is a screw adjustablevalve with a steel cap installed toconceal the adjustment. The cap isdesigned so that the internal edgesclamp into the groove of the valveadapter. Once the cap is installed,it cannot be removed without damagingthe cap and the valve. When a valve is ordered withthe tamper resistant option, it will be preset at thefactory, and the cap will be included in a separateplastic bag to allow for fine tuning at the customer site.Parker offers tamper resistant cap conversion kits formost pressure control valves. For kit numbers consultindividual valve pages.
Seals: The Winner’s Circle products feature astandard 4301 Polyurethane “D”-Ring. The “D”-Ringeliminates the need for backup rings. The majority ofthe products are available in Nitrile or FluorocarbonSeals. You should match the seal compatibility to thetemperature and fluid being used in your application.
Pressure Range: Parker offers a range of springsettings for the Pressure Control product line. Youwant to choose the setting that best meets theoperating range. The model callout is equivalent to themaximum setting (in psi) of the spring divided by 100(i.e. 50 = 5000 psi).

PRODUCT TYPES / APPLICATIONS
Direct Acting Relief ValvesDirect acting relief valves are designedfor fast response in intermittent dutyapplications. They are often used as aneconomical solution to clip pressure spikes.The poppet design allows for low leakage.
OPERATION - The valve poppet is held against the seat by thespring force. Inlet pressure on the nose (port 1) of the poppet actsagainst the spring force to unseat the poppet at the valve setting and allow flow to pass to tank. Since thepressure is working directly on the spring, this valve is very fast responding. It is not the best choice for systempressure regulation as it is slightly noisier than pilot operated relief valves and has higher pressure rise.Note: Any backpressure on port 2 would be additive to the spring setting.
Differential Area Relief ValvesDifferential area relief valves also arealso best suited for intermittent appli-cations where fast response is critical.These valves are often used as cross-over relief valves to chop pressure spikes.Due to their design, they generally can handle a larger flowrate and have a lower pressure rise than the standard directingacting relief. The poppet design allows for low leakage.
OPERATION - Pressure on the inlet (port 2) of the valve acts on the differential area of the poppet (differencebetween the O.D. of the poppet and the seat diameter) to produce a force which is opposed by the spring force.When pressure reaches the valve setting, the poppet is pushed off its seat, permitting flow to tank.Note: Any backpressure on port 1 would be additive to the spring setting.
Pilot Operated ReliefPilot operated relief valves are designedfor continuous duty applications. Due totheir stability and low pressure rise, thepilot operated relief is the best option forsetting the pressure of a hydraulic system.
OPERATION - When inlet pressure at the nose (port 1) exceedsthe valve setting, the pilot ball unseats. The pilot flow creates a pressureimbalance across the main spool causing the spool to move and allowing flow frominlet (port) 1 to tank (port 2.) Note: Any backpressure on port 2 would be additive to the spring setting.

Ventable Pilot Operated ReliefVentable relief valves are a unique typeof pilot operated relief. With this valve,you can control the pressure setting withthe internal adjustment as well as viaremote circuit. These valves are ideal incirucits where multiple pressures are needed.
OPERATION - This valve can be controlled by the adjustmentsetting on the valve, or a remote circuit via the vent line. When the vent lineis used, the smaller of the two pressure settings will determine the valve setting. In other words, if the pressuresetting of the remote circuit is less than the adjusted setting, then the valve will relieve at the remote setting. If thepressure setting of the remote circuit is greater than the adjusted setting, then the valve will relieve at the adjustedsetting. With the vent port (port 2) blocked, the valve operates like a standard pilot operated relief valve. Thus, asolenoid valve could be used on the vent port to select control between this valve another remote valve.

Dual Crossover Relief ValvesDual crossover relief valves providepressure surge protection for doubleacting hydraulic actuators. For bestresults, you always want to install thevalve as close to the actuator as pos-sible. The dual crossover feature can beachieved in two different methods. Oneway is to manifold two Differential Area Relief Valves into a single body.Parker offers three versions of this two cartridge arrangement. Theadvantage gained is higher flows can be pushed through this arrangement.The second method is to combine this dual function into a single cartridge.The single cartridge arrangement reduces cost considerably of the totalpackage. In addition, a standard common cavity line body can be used insteadof a special two body arrangement. The operation for the single cartridge style is shown below.
OPERATION - Pressure at port 1 acts on the spool to produce a force which is opposed by the spring setting.When pressure reaches the valve setting, the spool and poppet move relieving flow from port 1 to port 2. Whenport 2 is pressurized, the pressure acts on the differential area poppet to produce a force which is opposed by thespring force. When the pressure reaches the valve setting, the poppet is pushed off of its seat, relieving flow fromport 2 to port 1. Note: Due to the construction and flow paths through the valve, the relief pressure settings mayvary by approximately 300 psi from one direction to the other.

Differential AreaUnloading Relief ValveUnloading valves are differential arearelief valves that can also be fullydumped or unloaded via a remote signal.They are best suited for low flowaccumulator unloading circuits. They providea fixed percentage between load and unload pressures.This pilot valve would generally be used in conjunction with a logic element.
OPERATION - The fixed differential is provided by the pilot piston which has greater area than the dart seat. Withits greater area, the piston is able to hold the dart off its seat, permitting flow from pressure to tank, until pressureon the pilot piston falls below the fixed percentage of the valve settings.

Pressure Reducing / Relieving ValvesPressure reducing / relieving valves can be used to reduce the pressure in a leg of thecircuit lower than system pressure. The valve also acts as a relief valve, relieving anyshocks or surges that occur between the regulated port and the actuator. When the valveis in the relieving mode, the inlet port is blocked. Parker offers pressure reducing/relievingvalves in both pilot operated and directing acting styles. The direct acting version is generallyused in static applications where response is critical, or leakage is a concern.
Pilot OperatedOPERATION - The pilot section controlsthe valve setting when reducing. Aspressure at the regulated port exceedsthe valve setting, the pilot ball is un-seated. The pilot flow creates a pressureimbalance across the main spool causing the spool tothrottle in order to maintain constant downstream pressure.A shock or surge at the regulated port shifts the spool, relieving flow to tank.
Direct ActingOPERATION - As pressure at the regulated port exceedsthe valve setting, the valve throttles or closes in order tomaintain constant downstream pressure. A shock or surgeat the regulated port further shifts the spool, relieving flowto tank. This valve is not intended for rapidly changing flowswhich could lead to instability.

Pilot Operated Reducing ValvePilot operated pressure reducing valvescan be used to reduce the pressure ina leg of the circuit lower than systempressure. Thus, they can be used toprovide protection to downstreamcomponents from higher pressures.
OPERATION - The pilot section controls the valve setting whenreducing. As pressure at the regulated port exceeds the valve setting,the pilot ball is unseated. The pilot flow creates a pressure imbalance across themain spool causing the spool to throttle in order to maintain constant downstream pressure. The normally opendesign will allow flow to pass from inlet to reduced port with the only restriction being the pressure drop.

Pilot Operated Sequence ValvesSequence valves are used to control the sequence of operation of two or more hydraulic actuators. The sequencevalve pressure is set higher than the first actuator operation pressure. Once the first actuator has completed itscycle, the sequence valve opens allowing the second actuator to move. Parker’s line of pilot operated sequencevalves include a series of internally piloted, externally drained valves and a series of externally piloted, internallyvented valves. Parker also offers a line of direct acting sequence valves which are ideal for piloting logic elementsin steady state applications.
P.O. Sequence (Internally Piloted, Externally Drained)OPERATION - For this valve, the pilot pressure is sensedfrom the inlet of the valve (port 1). When the pilot pressureexceeds the valve setting, the pilot section opens creating apressure imbalance across the main spool. This causes thespool to move allowing the flow to pass from the nose of thecartridge (port 1) to the actuator port (port 2). By externally draining the pilot flowdirectly to tank (port 3), the valve is insensitive to back pressure at the sequence port.
P.O. Sequence (Externally Piloted, Internally Vented)OPERATION - For this valve, the pilot pressure is obtainedfrom an external source and not from the pressure port.When the external pilot pressure (port 1) exceeds the valvesetting, the pilot section opens creating a pressure imbalanceacross the main spool. This causes the spool to move allowingthe flow to pass from the side of the cartridge (port 2) to the actuator port (port 3).Any pressure at port 3 is additive to the pressure setting. It is most common for port 3 to be connected to tank.
D.A. Sequence (Internally Piloted, Externally Drained)OPERATION - In the steady state condition,all three ports are blocked with the springchamber drained to port 3. When thepressure at port 1 exceeds the valvesetting, the spool moves allowing flow fromthe nose of the cartridge (port 1) to theactuator port (port 2). By externally draining the springchamber directly to tank (port 3), the valve is insensitive to back pressure at the sequence port.
D.A. Sequence, N.O. (Externally Piloted, Externally Drained)OPERATION - With no pressure at the pilotport (port 1), bi-directional flow is allowedbetween port 3 and port 2. When the pilotpressure at port 1 exceeds the valve settingthe spool moves blocking both port 3 andport 2. By externally draining the springchamber to tank (port 4), the valve is insensitive to back pressure at the sequencing ports.
D.A. Sequence, N.C. (Externally Piloted)OPERATION - With no pressure at the pilotport (port 1), both port 3 and port 2 areblocked. When the pilot pressure at port 1exceeds the valve setting, the spool movesopening a path and allowing flow fromport 3 to port 2. This valve internally drainsthe spring chamber to tank via the sequencing port,thus any backpressure on port 2 would be additive to the spring setting.

General DescriptionDirect Acting, Normally ClosedSequence Valve (Externally Piloted).With no pressure at the pilot port(port 1), both port 3 and port 2 areblocked. When the pilot pressure at port 1exceeds the valve setting, the spool moves opening apath and allowing flow from port 3 to port 2. This valveinternally drains the spring chamber to tank via thesequencing port, thus any backpressure on port 2would be additive to the spring setting.
