3 PRPS-0 DESCRIPTION This unit is a, SCREW IN CARTRIDGE STYLE, HYDRAULIC PRESSURE REDUCING VALVE, designated to act as a pressure- regulating device for secondary circuit. OPERATIONS This valve will allow flow from port to port until pressure in port exceeds the force of the spring bias then the spool will shift and block flow from port to port and maintain the same pressure as the force of the spring setting regardless of the pressure at port. FEATURES AND BENEFITS Leakproof screw adjustment. Pressure in tank port (3) will add to the bias spring setting, and is limited to 000 PSI. Adjusting screw can not be backed out of the valve. Overset protection-pilot spring can not go solid. Hardened precision fitted spool & cage provides reliable, long life. A unique self aligning (floating) cage provides very low hysteresis and reliable operation. All external carbon steel parts are plated for longer life against the elements. Valve is available with screw, tamperproof, capped and handknob adjustments. All cartridge valves are 00% functionally tested. Industry common cavity. SPECIFICATIONS PRESSURE REDUCING VALVE OPERATING PRESSURE: 5,000 PSI [350 Bar] PROOF PRESSURE: 0,000 PSI [700 Bar] FLOW:.0 GPM [46 L/M] nominal. See performance chart. INTERNAL LEAKAGE: 5 cu.in./min [.8 85% of crack pressure. DEFINITION OF CRACK: evident at 0.06 GPM [0.5 LPM] VALVE HOUSINGS: 500 PSI [75 Bar] = Aluminum - Anodized PSI [350 Bar] = Steel - Unplated. OPERATING TEMPERATURE: -40 to +50 F. [-40 to +0 C.] OPERATING MEDIA: All general purpose hydraulic fluids such as MIL-H-5606, SAE-#0, SAE-#0, etc. INSTALLATION: No restriction.
