Inlet Check Valve 23421274 Ingersoll Rand Air Compressor Valve

The air compressor inlet valve regulates the capacity of your rotary screw compressor.

The air compressor unloader valve regulates the amount of air that is sucked in by your air compressor. By opening and closing the air intake, the capacity of a rotary screw compressor is regulated.

This valve is also commonly called an inlet valve, intake valve, unloader and unload valve.

Most unloaders are of the LOAD/UNLOAD type. Which means they are either completely open (compressor loaded) or completely closed (compressor unloaded). In unloaded state, when the unloader is closed, the unit will consume about 30% of it’s nominal power.

APPLICATION:

Insalld at the compressor inlet to control compressr capacity At the sat-up the vave suays open oll a contol signal is appliled to close the valve and restrict the flow. During normal operation the valve open and close in response to a control signal to meet the air demand. At the shut-down a check valve stays closed to prevent back flow through the compressor. The valve can be ordered in the non-return working system.
 

INSTALLATION:

At the suction flange of the air end, either directy or by flange adaptor, depending on the type of air-end. The 0N/OFF system must be connect to the signal pressure and solenoid valve.
 

REPLACEMENT:

The stress on valve parts depends on compressor aplcation and operating parameters. Inspect the valve and rplace, using VMC spare part kit, after 8.000 operating hours.
