Technical Specifications Supply: 24 V DC ±10%; control input: 4–20 mA; position feedback: 4–20 mA; flow range: 0–45 kg/h natural gas; operating pressure: 0.5–10 bar(g); operating temperature: -30 °C to +120 °C; enclosure: IP65.
Functional Features Closed-loop position control; integrated LVDT position feedback; improved accuracy and repeatability; linear flow characteristic; zero shutoff; fault detection.
Application Scenarios Precision engine fuel control, load-sensitive gas engines, emissions-compliant engine systems, high-accuracy gas metering, variable-speed gas engines.
Performance Parameters Position accuracy: ±0.5% FS; flow linearity: ±2% FS; repeatability: ±0.5% FS; response time: < 20 ms.
Material Composition Aluminum valve body; stainless steel plunger; LVDT position sensor; solenoid coil; NBR seals.
Structural Characteristics In-line flow body; top-mounted solenoid and position sensor; side process connections; top electrical connector.
Working Principle Internal position sensor provides real-time plunger position feedback to the control circuit, which adjusts solenoid current to maintain target position, delivering improved flow accuracy and immunity to pressure and temperature variations.
Installation Requirements Install inline with flow arrow; connect control input, position feedback and power; calibrate zero, span and feedback during commissioning.
