Woodward 8440-1936 High Pressure CANopen Proportional Gas Valve

Product Brief Introduction High pressure CANopen digital proportional gas valve with pressure balanced poppet design, for high pressure gas engine network control.
Tag:

Technical Specifications Supply voltage:24 V DC ±10%; Communication:CANopen; Operating pressure:2–22 bar(g); Operating temperature:-30 °C ~ +120 °C; Enclosure:IP65.

Functional Features CANopen digital bus; pressure balanced poppet; closed-loop position feedback; fault diagnosis; high pressure resistant structure.

Application Scenarios High pressure pipeline gas engine, networked compression unit, wellhead gas power generation system.

Performance Parameters Flow linearity:±2.8% FS; Repeatability:±1.2% FS; Bus update cycle:10 ms.

Material Composition Forged steel valve body; hardened stainless steel poppet; FKM high pressure seals; CANopen electronic module.

Structural Characteristics Pressure balanced poppet; top solenoid and CAN communication electronics; high pressure threaded ports.

Working Principle CANopen bus receives opening command. The pressure balanced poppet minimizes gas pressure interference, position feedback circuit adjusts solenoid thrust to control gas flow.

Installation Requirements Install inline; connect CAN bus and power; pressure test pipeline; set CAN node address and calibrate valve.

Usage Notes Use shielded CAN cable; perform pressure leak test before commissioning; avoid medium containing solid particles.
