PEEK, Carbon The compressor air valve is composed of a valve seat, a valve cover, a valve plate, a spring and a fastening bolt. The working process is based on the gas pressure in the cylinder. The pressure difference between the gas pressure and the spring force before entering the cylinder pushes the valve plate up and down to open. In the closed state, the main force component is the valve piece of the air valve, and the wearing part is the valve piece. The breakage of the valve piece may cause the sealing surface of the valve seat to be damaged, or even fall into the cylinder of the compressor, causing the piston to move. The abnormal sound is even damaged or even damages the piston or cylinder. Therefore, the performance of the valve material of the compressor determines the key factor of the service time of the compressor valve, and it is also a powerful guarantee for continuous and long-term operation of the compressor.
