Technical Specifications Valve: 2301A analog proportional, 12 gpm, 100–250 psi supply; relay interface: 6 SPDT outputs, 5 A at 250 V AC; supply voltage: 24 V DC ±10%; control input: 4–20 mA; operating temperature: -30 °C to +70 °C; enclosure: IP65 valve section, IP20 relay section.
Functional Features Proportional hydraulic control; six configurable relay outputs; position, fault and limit indication; zero and span adjustment; pressure-compensated flow.
Application Scenarios Complex turbine control systems, engine fuel control with multiple alarms, industrial hydraulic system status monitoring, process valve sequencing and interlock.
Performance Parameters Valve linearity: ±2% full scale; relay accuracy: ±2.5% full stroke; repeatability: ±1% full scale.
Material Composition Ductile iron valve body, stainless steel internal components, sheet metal relay enclosure, silver alloy relay contacts, nitrile rubber seals.
Structural Characteristics Modular stacked assembly; standard valve mounting footprint; multi-pin electrical connector; standard hydraulic ports.
Working Principle The analog input signal proportionally positions the valve spool. Multiple position-sensing relays activate at pre-determined stroke positions, providing discrete signals for position indication, limit control, fault detection and sequence interlock.
Installation Requirements Mount on standard hydraulic subplate; connect supply, return and actuator lines; wire control, power and all relay outputs; calibrate valve and all relay setpoints.
