Unlike the GS51 HW diaphragm valve, this valve controlled by pneumatic actuator and manual override, which makes it possible to implement remote control valve on explosive industries, and use a GS52A HW diaphragm valve in automation systems. In GS52A HW Diaphragm Valve of Flow Transit Type much less pressure lossthan standard globe valves.

Manual override allows manually manage opening and closing of the diaphragm valve in case of refusal or absence pressure in the pneumatic drive system.

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.
