rotary screw air Compressor Inlet Valve AIV-50A-L intake valve normally open:

Our product portfolio includes valves in the volume flow range between 0,3 and 70m³/min. The intake valve types AIV and RS are partly patented, simply-constructed devices with only a few wearing parts. They are reliable and robust valves, straightforward to service and replace.

The most significant technological progress of the AIV-typed intake valves is that they integrate the features of a normal open valve (with its simple structure) and those of a normal closed valve (with its low strain during start-up phase).

The RS-typed intake valves are necessary to realize On/Off or 0-100% suction volume flow adjustments. Combined with a non-return valve, the flowing back of lubricating oil will be prevented.

The unique air intake flow passage prevents pressure losses. We supply electrically and pneumatically controlled intake valves.
