Product Description 

The air inlet valve of screw air compressor (also known as load reducing valve) is mainly composed of valve body, valve core (piston), air circuit integrated block, solenoid valve and proportional valve (volume regulating valve).The opening degree of the load reducing valve determines the size of the air intake, is the volume of air (pressure) adjustment actuator.When the compressor starts, the load relief valve valve is in the closed position to reduce the starting load of the compressor;During normal operation, according to the measured exhaust pressure and the set value of comparison, proportional valve began to work, so that the load reducing valve valve with the rise and fall of pressure and gradually closed or opened, so that the displacement of air in proportion to smaller (or rise), this process is called proportional adjustment process, control air compressor to complete loading, unloading and other actions.
