Product Brief Introduction CANopen digital proportional gas admission valve with LVDT closed-loop feedback, for medium flow gas engine networked fuel control systems.
Tag:

Technical Specifications Supply voltage: 24 V DC ±10%; Communication: CANopen CiA408; Operating pressure: 0.4–10 bar(g); Operating temperature: -30 °C to +120 °C; Enclosure rating: IP65; Position resolution:12-bit.

Functional Features CANopen bus communication; LVDT closed-loop position control; remote parameter configuration; self-diagnosis and fault reporting; linear flow characteristic.

Application Scenarios CANopen-based gas engine control, distributed cogeneration power plant, biogas generator network control.

Performance Parameters Flow linearity: ±2.3% FS; Repeatability: ±1.0% FS; Bus update cycle:10 ms.

Material Composition Aluminum valve body; stainless steel valve internals; FKM seals; solenoid coil; CAN communication electronic board.

Structural Characteristics Inline flow body; top-mounted solenoid and CAN electronics assembly; sealed CAN bus connector; threaded process ports.

Working Principle CANopen master sends valve opening setpoint. Onboard controller compares command with real LVDT position feedback, adjusts solenoid current to modulate gas flow area accurately.

Installation Requirements Install inline following flow arrow; connect CAN bus and power cable; set CAN node address and baud rate; perform valve calibration.
