The ICV-40 is an intake control valve designed for industrial power frequency oil-injected screw air compressors . It regulates the amount of air entering the compressor, controlling the loading and unloading cycles to maintain system pressure . It is a normally open (N/O) type valve that closes in response to a control pressure signal

Features and advantages of the intake valve
Combines multiple functions (discharge valve, air admission valve, solenoid valve, and proportional valve) into a single unit for easy installation and reduced leak points .
Special structure design solves the problem of high start-up load, protecting the motor during startup .
Prevents oil backflow through the compressor during shutdown, eliminating the need for a separate check valve .
Eliminates cavitation noise from the air end by admitting air during unloading .
The proportional valve exhausts only during capacity regulation, not during normal loaded operation, saving energy .
Supports both on/off control and capacity regulation (proportional control) for stable pressure maintenance.

The ICV-40 is specifically engineered for power frequency oil-injected screw compressors across various industrial sectors . It is compatible with compressor systems ranging from 5.5 kW to 400 kW, handling flow rates from 0.84 to 75.1 m³/min at working pressures of 6~13 bar . Typical applications include general manufacturing facilities, automotive workshops, and industrial plants where reliable compressor unloading and capacity control are essential for energy-efficient operation.
