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.
 

The main function of the inlet butterfly valve is to adjust the air intake of the air compressor under the action of the control system so as to keep an economical match with the air consumption of the user.

Shanghai everes valve for Ingersoll rand, shouli, Elgi and other large displacement screw air compressor design and development of the intake butterfly valve, the product service life can reach more than 5 million times, basically will not be damaged, belongs to a single rotary flow control valve.
