Application: R5 Pressure Control Valves

     Do you need a SAE 4 bolt mounted, pilot operated pressure control valve to fasten directly onto your hydraulic pump or into your hydraulic piping? Parker’s R5 series valve will meet or exceed your expectations. Available for use as R5V 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. This reducing valve is also available with an integral reverse flow check valve. Each type of R5 valve has three sizes; 3/4” (SAE -12, Code 61 & 16 GPM), 1” (SAE -16, Code 61, & 53 GPM) and 1-1/4” (SAE -20, Code 61, & 120 GPM), to suit your flow rate requirements. There is even a 1-1/2” size (SAE -24, Code 62, & 120 GPM); only available in the R5V relief and the R5U unloading models. Any of these R5 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. The 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. The body style exists in either 2 port (for inline mounting) or in 3 port (for Teeing off of a line).
