Technical Specifications Pressure range: 50–300 psi adjustable via electrical signal; control input: 4–20 mA; flow capacity: 15 gpm maximum; supply pressure: 500 psi maximum; response time: < 50 ms; repeatability: ±1% of full scale; operating temperature: -20 °C to +90 °C; connection size: 1/2 inch NPT.
Functional Features Electrically proportional pressure control; adjustable pressure range via 4–20 mA signal; poppet design for low leakage; zero pressure at zero signal; overpressure protection; fast response.
Application Scenarios Hydraulic system pressure regulation, governor control pressure setting, load pressure control, hydraulic overload protection, variable pressure hydraulic circuits.
Performance Parameters Pressure accuracy: ±2% of setpoint; response time: < 50 ms; repeatability: ±1%; leakage: < 0.1 gpm at set pressure.
Material Composition Steel valve body, stainless steel poppet and seat, solenoid operator with copper coil, adjustment spring, nitrile seals.
Structural Characteristics Inline poppet valve body; top-mounted solenoid operator; side inlet and outlet ports; integral 150 psi minimum pressure setting.
Working Principle The 4–20 mA control signal varies current through the solenoid coil, producing proportional magnetic force that opposes the poppet spring. The valve opens at the pressure corresponding to the input signal, maintaining system pressure proportional to the electrical command.
