Compressor unloading valves 2/2
Solenoid valves 2/2 and 3/2-way
2/2-way compressor unloading valves are used during start-up of screw and piston compressors to depressurise the pressure vessel and reduce the inrush current of the drive motor. The ENTLAST series covers versions for screw compressors (ENTLAST 12 SCH, G 1/2" and ENTLAST 14 SCH, G 1/4", both 230 VAC) and for piston compressors (ENTLAST 10, G 1", and ENTLAST 12, G 1/2", both 230 VAC). All types operate normally open (NO).
| Type | Port | Compressor type | Voltage |
|---|---|---|---|
| ENTLAST 14 SCH | G 1/4" | Screw compressor | 230 VAC |
| ENTLAST 12 SCH | G 1/2" | Screw compressor | 230 VAC |
| ENTLAST 12 | G 1/2" | Piston compressor | 230 VAC |
| ENTLAST 10 | G 1" | Piston compressor | 230 VAC |
Typical applications: Start-up unloading on screw and piston compressors in compressed air supply systems; protection of start capacitors and motor windings; replacement and retrofitting on Boge compressors and comparable makes; use in industrial compressed air stations and commercial workshops.
