Technical Specifications Supply voltage: 24 V DC ±10%; Control signal: 4–20 mA; Position feedback:4–20 mA; Operating pressure:0.5–11 bar(g); Operating temperature:-30 °C ~ +120 °C; Enclosure:IP65.
Functional Features Analog 4-20mA control and feedback; closed-loop LVDT position feedback; low hysteresis; zero shutoff; overpressure protection; vibration resistant.
Application Scenarios Stationary gas engine speed governing, generator load control, biogas engine fuel metering, engine emission optimization control.
Performance Parameters Flow linearity:±2% FS; Repeatability:±0.8% FS; Hysteresis:<1% FS; Response time:<22 ms.
Material Composition Aluminum valve body; stainless steel valve internals; FKM seals; solenoid coil; LVDT position sensor.
Structural Characteristics Inline flow body; top mounted solenoid and LVDT assembly; threaded process connections; sealed electrical connector.
Working Principle 4–20mA input defines target valve opening. LVDT detects real plunger position, control circuit adjusts solenoid current to eliminate position error, realizing stable proportional gas flow modulation.
Installation Requirements Install inline matching flow direction; wire power, control signal and feedback signal; calibrate zero and span of valve opening and feedback signal.
