Application: Denison R4 Pressure Control Valves


     Anyone looking for reliable, capable and accurate, pilot operated pressure control valves; need look no farther than Parker’s R4 series. Available for use as R4V relief, R4U unloading, R4S sequence or R4R reducing functions, they are rated up to 5,000 PSI maximum and can handle flows up to 160 GPM (this is more than 150 horsepower). As a relief valve it will safely limit the maximum pressure a hydraulic circuit can reach. The unloading valve is used to sense the pressure in another part of a hydraulic circuit and vent a pump’s flow to tank when it is not needed – this is a great energy saver when used in conjunction with another pump (high/low system) or with an accumulator. Sequence valves are used to control the operational order that functions within a hydraulic system must execute in. The R5R reducing valve, limits the pressure to any one hydraulic circuit, ensuring the force exerted by its actuators do not exceed any specific level. Each type of R4 valve has three sizes; 3/8” (16 GPM), ¾” (53 GPM) and 1-1/4” (120 GPM), to suit your flow rate requirements. Any of these R4 valves come with one of three adjustable pressure levels (2,000 PSI, 3,000 PSI or 5,000 PSI), to make sure that they cannot be inadvertently adjusted too high. These pressure adjustments can be made with any of three devices; a hand knob & jam nut, an acorn nut & lead seal or a hand knob & key lock. Parker has designed these valves with removable pilot sections; in this way a solenoid valve (Parker’s VV01) or an electronic proportional pilot (Parker’s 4VP01) can be sandwiched between this pilot and the main valve body. The VV01 is used to electrically vent the R4 valve pilot and the 4VP01 is used to control the actual pressure level of the R4 valve remotely. To make this valve series even more flexible, they can be purchased as a cartridge, a manifold or a line mounted version. Cartridges can be inserted into your own manifold design, the manifold mounted version is made to international standards for mounting onto subplates or manifolds and the line mounted units are for incorporating into the hydraulic system pipe work.
