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: -40 °C to +125 °C; Enclosure rating: IP65.
Functional Features Enhanced low-friction moving assembly; wider operating temperature range; closed-loop LVDT position feedback; low hysteresis; zero gas shutoff.
Application Scenarios Heavy-duty gas generator sets, outdoor cogeneration units, engines with large ambient temperature variation.
Performance Parameters Flow linearity: ±2.0% FS; Repeatability: ±0.8% FS; Hysteresis: <0.9% FS; Response time: <20 ms.
Material Composition Aluminum alloy valve body; hardened stainless steel plunger; high-temperature FKM seals; optimized solenoid coil; high-precision LVDT sensor.
Structural Characteristics Inline flow body; reinforced top solenoid and sensor assembly; anti-loose fasteners; threaded process connections.
Working Principle Same closed-loop position control principle as 8440-2150. Optimized internal friction parts reduce position drift under wide temperature and vibration conditions.
Installation Requirements Install inline vertically; connect power, control and feedback wiring; calibrate zero and span after thermal stabilization.
