Technical Specifications Supply voltage:24 V DC ±10%; Control signal:4–20mA; Operating pressure:2–22 bar(g); Operating temperature:-30 °C ~ +120 °C; Enclosure:IP65.
Functional Features High pressure rated body; pressure balanced poppet; 4-20mA analog control; zero shutoff; corrosion resistant internals.
Application Scenarios High pressure wellhead gas engine, pipeline compression engine, high pressure gas cogeneration unit.
Performance Parameters Flow linearity:±3% FS; Repeatability:±1.5% FS; Response time:<28 ms.
Material Composition Forged steel valve body; hardened stainless steel poppet; FKM high pressure seals; high force solenoid coil.
Structural Characteristics Pressure balanced poppet structure; top-mounted solenoid; high pressure threaded process ports.
Working Principle Pressure balanced poppet eliminates most pressure force from inlet gas. 4–20mA signal changes solenoid thrust to adjust poppet lift and gas flow cross-section.
Installation Requirements Use high pressure rated pipe fittings; install inline; conduct pressure leak test after installation; calibrate zero and span.
Usage Notes Do not exceed maximum working pressure; install high precision filter upstream; inspect seal aging periodically.
