ZMA/BS Pneumatic Thin Film Angle High Pressure Regulating Valve

Product Introduction: ZMA/BS Pneumatic Thin Film Angle High Pressure Regulating Valve, consisting of a pneumatic thin film multi spring actuator and an 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.

■overview

ZMA/BS-220、 The 230 pneumatic diaphragm angle type high-pressure regulating valve consists of a pneumatic diaphragm multi spring actuator and an angle type 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.
