Technical Specifications Inlet pressure range: 150–500 psi; outlet pressure range: 50–150 psi adjustable; flow capacity: 15 gpm maximum; pressure adjustment sensitivity: ±0.5 psi; operating temperature: -20 °C to +120 °C; pressure rating: 600 psi maximum; connection size: 1/2 inch NPT.
Functional Features Pilot-operated pressure regulation; adjustable outlet pressure setpoint; high flow capacity; pressure compensation for varying inlet pressure; integral inlet filter; vibration-resistant design.
Application Scenarios Hydraulic governor control oil supply, turbine control system pressure regulation, industrial hydraulic system pressure control, actuator supply pressure regulation.
Performance Parameters Pressure regulation accuracy: ±1% of setpoint; response time: < 100 ms for 20% inlet pressure change; flow stability: < ±2% pressure variation over full flow range.
Material Composition Ductile iron valve body, stainless steel spool and pilot assembly, carbon steel adjustment spring, nitrile rubber seals, bronze filter element.
Structural Characteristics Inline body configuration; top-mounted adjustment screw with locknut; side inlet and outlet ports; integral 10 micron inlet filter; mounting pad for manifold installation.
Working Principle Supply pressure enters the valve and acts on the pilot stage. The pilot regulates control pressure on the main spool, which modulates flow to maintain outlet pressure at the value set by the adjustment spring, compensating for variations in inlet pressure and outlet flow.
