Solenoid / Control Valve Assembly with Coil for FIAC NK40 Rotary Compressors (PN 1127190007 EX 7194390000)

Description

The control solenoid valve assembly with coil (EL/VA Command NK40) for FIAC NK40 rotary screw air compressors is a vital electro-pneumatic component engineered for precise system regulation.

This valve controls the pneumatic signal directed to the intake regulator, enabling the compressor to switch seamlessly and efficiently between "loaded" mode (air compression) and "unloaded / idle" mode (energy-saving idle running). The included solenoid coil ensures rapid, dependable actuation triggered directly by the compressor’s electronic control unit.

- Technical & Installation Tips:

- Electrical & Voltage Verification:Prior to installation, ensure the coil voltage (V) and frequency (Hz) rating match the electrical specifications of your FIAC control panel/unit.
- Safety Protocols:Completely isolate the compressor from the main electrical power supply and depressurize the pneumatic system entirely before disconnecting any electrical wiring or air lines.
- Pneumatic Fittings Seal:When reassembling pneumatic quick-connects or threaded fittings, apply appropriate thread sealant sparingly to prevent debris or sealant excess from fouling the internal valve channels.
- Connector Weatherproofing:Ensure the solenoid plug/connector is seated correctly with its sealing gasket tightened securely to maintain the IP protection rating against dust, oil, and moisture ingress.
- Troubleshooting Tip:If the compressor fails to switch between load and unload cycles, use a multimeter to check solenoid coil continuity and verify that the electronic controller is delivering the appropriate signal voltage.
