Intake Valve for Portable Oil-injected Screw Compressor

Features：

1、Application: Power Frequency Oil-injected Screw Compressor

2、It’s N/C type and will open in response to a control pressure signal.

3、Intake valve has piston type check structure to prevent oil injection through the compressor at shutdown.

4、Intake valve can eliminate cavitation noise from air-end with an optional air admission valve when unloading.

5、Discharge valve, optional air admission valve, proportional valve, solenoid valve and drain filter integrate an intake valve.
