Technical Specifications Valve: 2301A analog proportional, 12 gpm flow, 100–250 psi supply; relays: 2 SPDT channels, 5 A at 250 V AC; supply: 24 V DC ±10%; control input: 4–20 mA analog; operating temperature: -40 °C to +75 °C; enclosure: IP65 wetted section, IP20 electrical section.
Functional Features Analog proportional flow control; two isolated relay status outputs; adjustable open/close limit indication; zero and span calibration; pressure-compensated flow regulation.
Application Scenarios Valve position limit indication, hydraulic actuator end-of-travel signaling, turbine valve position feedback, engine fuel system limit switches.
Performance Parameters Valve linearity: ±2% full scale; relay position accuracy: ±3% full stroke; response time: < 180 ms total.
Material Composition Ductile iron body, stainless steel spool assembly, thermoplastic relay housing, silver alloy relay contacts, nitrile rubber hydraulic seals.
Structural Characteristics Integrated valve and relay package; standard 2301 mounting pattern; side electrical connector; SAE standard hydraulic ports.
Working Principle The analog control signal modulates valve spool position to control hydraulic flow. Two position-actuated relays switch state at pre-set travel points, providing end-of-travel and fault status signals to the control system.
