Control systems
for oil injected screw compressors
Providing proportionate outlet pressure depending on inlet pressure.
Positive acting controller: Supplies proportionally increasing signal with increasing inlet pressure
Negative acting controller: Supplies proportionally decreasing signal with increasing inlet pressure
- Maximum working pressure:
- 16 or 28 barg I 230 or 410 psig
- Operating pressure:
- 2 to 25 barg I 30 to 365 psig
- Ambient temperature:
- -20 to +120 °C I -4 to +248 °F
Technical Data sheet
At idling the valve releases air to lower the discharge pressure and reduce energy consumption.
At stop the valve releases the discharge pressure inside the compressor for restart.
VVF:
Normally open valve, activated pneumatically by integrated solenoid valve.
Add-on option for HOERBIGER suction controllers
HEV:
Normally closed valve, activated with pneumatic signal.
AVP:
Solution for portable compressors only.
Normally open valve, activated via proportional pneumatic signal.
- Maximum working pressure:
- 16 or 28 barg I 230 or 410 psig
- Ambient temperature:
- -20 to +120 °C I -4 to +248 °F
Pneumatic cylinder usable inside of compressors withstanding high temperature and harsh environmental conditions.
Add-on option for HOERBIGER suction controllers.
- Maximum working pressure:
- 16 barg I 230 psig
- Ambient temperature:
- -20 to + 120 °C I -4 to 248 °F
