Disk valves

11 3

Disc valves are designed for reciprocating compressors with a shaft speed up to 1250 rev / min. and a pressure difference of up to 8 MPa. Working temperature of product from -200 º C up to + 380 º C. The basis of the locking mechanism of the disc valve is a  plate, damping disc and springs, that ensure the tightness of the valve. The damping elements use for reducing shock loads and extending the life of the valve.  
Springs, damping plate and locking plate are made of stainless steel. The springs have a improved dynamic characteristics.They have a special coating resistant to corrosion and hydrogen embrittlement. The saddle, lift limiter, the locking elements and pressure mechanism depending on the operating conditions of the compressor produced from stainless steel or carbon steel.
