Unlike the GS51 HW diaphragm valve, this valve controlled by a pneumatic actuator, which makes it possible to implement remote control valve on explosive industries, and use a GS52 HW diaphragm valve in automation systems. In GS52 HW Diaphragm Valve Transit Flow much less pressure lossthan standard globe valves.
The diaphragm is made of various materials for specific valve operating conditions and protects the body and control parts from the ingress of the working medium. For various operating conditions, the body is made of various materials:
- cast iron
- cast iron with ebonite
- light metal, etc.
The diaphragm is controlled in the open and closed position, causing the valve works even in a vacuum.
It is recommended not to exceed certain internal pressure values, depending on the valve diameter, specified in the technical documentation. Valves are manufactured with diameters from 15 to 350mm and widely used in chemical industry and water treatment plants.
