Sanitary tri-clamp actuated diaphragm valve plug valves for high purity process piping applications
Combining world-class industry experience with engineering and manufacturing facilities located in both the USA and Canada. Our R&D, engineering, and manufacturing groups are committed to providing high-quality valves that are unsurpassed by any of our competitors.
Diaphragm actuator valves are used to control flow rates to exact specified levels via air-flow. Actuator valves have a factory-set option of either fully closed or fully open. When air pressure is applied to the valve via the NPT port connection, the valve will open up. However, when the air pressure is released the valve will return to its normal position of either fully open or fully closed.
