ZMA/BS-220、 320 Pneumatic Thin Film Angle High Pressure Regulating Valve
1、 Product Details
Product model: ZMA/BS
Product Name: Pneumatic Control Valve Pneumatic Thin Film High Pressure Angle Control Valve
ZMA/BS-220, 320 pneumatic diaphragm angle high-pressure regulating valve, composed of pneumatic diaphragm multi spring actuator and angle high-pressure valve.
Adopting a transparent valve seat structure, the valve seat is easy to replace and has good sealing performance. The valve seat and valve core head with DN ≤ 25 are made of 6YC1 hard alloy, while the valve core with DN ≥ 32 is made of welded tungsten cobalt alloy, which has the advantages of gas corrosion resistance, impact resistance, etc., greatly improving the service life.
Widely used in various chemical, refining and other industries, especially suitable for high-pressure and high-pressure differential medium regulation in the synthesis of ammonia and urea industries.
