Technical Specifications Supply voltage: 24 V DC ±10%; Control signal: 4–20 mA; Position feedback: 4–20 mA; Operating pressure: 0.4–10 bar(g); Operating temperature: -30 °C to +120 °C; Enclosure rating: IP65.
Functional Features 4-20mA analog control and feedback; built-in LVDT closed-loop position control; linear flow characteristic; full shut-off at zero command; vibration-resistant industrial mechanical structure.
Application Scenarios Stationary gas generator sets, cogeneration engine fuel control, biogas engine speed and load governing.
Performance Parameters Flow linearity: ±2.2% full scale; Repeatability: ±0.9% FS; Step response time: <22 ms; Internal leakage: <0.5% FS.
Material Composition Aluminum alloy valve body; stainless steel plunger and valve seat; FKM fluororubber sealing ring; solenoid coil; LVDT position sensor.
Structural Characteristics Inline straight-through flow structure; top-mounted solenoid and sensor assembly; threaded process ports; sealed multi-pin electrical connector.
Working Principle The 4–20mA input signal defines the target valve opening. The LVDT sensor detects real-time plunger position, the internal control circuit adjusts solenoid current to eliminate position error, realizing stable proportional gas flow modulation.
Installation Requirements Install inline following the flow arrow mark; mount vertically with solenoid on top; wire power, control signal and feedback signal; perform zero and span calibration during commissioning.
