Technical Specifications Supply voltage:24 V DC ±10%; Control signal:4–20mA; Position feedback:4–20mA; Operating pressure:0.4–10 bar(g); Operating temperature:-30 °C ~ +120 °C; Enclosure:IP65.
Functional Features High precision LVDT closed-loop feedback; low hysteresis mechanical structure; zero shutoff; anti-vibration design.
Application Scenarios Low NOx gas engine, emission-compliant generator set, high precision load control cogeneration system.
Performance Parameters Flow linearity:±1.8% FS; Repeatability:±0.7% FS; Hysteresis:<0.8% FS; Response time:<20 ms.
Material Composition Aluminum valve body; polished stainless steel plunger; low-friction FKM seals; high-precision LVDT sensor; solenoid assembly.
Structural Characteristics Inline flow structure; top-mounted solenoid and precision sensor assembly; threaded process ports.
Working Principle 4–20mA analog signal sets target opening. High-precision LVDT feeds back plunger position, control circuit continuously corrects solenoid force to maintain stable flow.
Installation Requirements Install inline vertically; use shielded analog signal cable; calibrate zero and span carefully during commissioning.
