Product Features
Integrated all-in-one design: Built-in I/P electro-pneumatic converter, no extra conversion device required. Simplifies wiring and mechanical structure, reduces installation cost and potential failure points.
Fail-safe protection: Equipped with spring return structure. Automatically moves valve to preset safe position upon loss of control signal or supply air to avoid production hazards.
High-precision stable control: Ultra-low stroke hysteresis and dead band, adjustable response speed, suitable for fine fluid regulation and continuous stable production.
Robust for harsh environments: Epoxy coated aluminum alloy housing, NBR/EPDM diaphragm, 316 stainless steel spring and output shaft. Dustproof, waterproof and corrosion resistant for severe field conditions.
Easy maintenance: Visual 90° stroke position indicator for direct valve status check. Adjustable spring range and stroke speed. Optional valve position transmitter for 4-20mA position feedback and emergency shut-off lock valve.
High safety reliability: SIL2 certified, meets strict requirements of safety instrumented systems for high-risk chemical and oil & gas applications.
