The valve assembly includes a suction valve and an exhaust valve; each time the piston moves up and down once, both the suction valve and the exhaust valve open and close respectively, thereby controlling the compressor and enabling it to go through the four working processes of expansion, suction, compression, and exhaust.
It controls the exhaust and intake of gas in the cylinder, achieving automatic opening and closing through the pressure difference across the air valves, without the need for a dedicated control mechanism
Controls air volume and also serves as a check valve
Complete the intake and exhaust of the compression chamber and prevent gas backflow
The valve is the most critical component in reciprocating compressors, as it has a decisive impact on the compressor’s efficiency, power, exhaust volume, and reliability
