Learn about Wafer Style Butterfly Valves
Wafer butterfly valves are used to control the flow of water and other compatible media. The wafer butterfly valve easily mounts between two ANSI/ASME 150 lb. pipe flanges with through bolts and nuts.
Valworx electric actuators rotate an output drive to open and close butterfly valves. Electric actuators provide a reliable and economical method of operating these valves from a remote location. For modulating valve applications, an electric actuator with EPS positioning can control the valve flow with a 4-20mA command signal.
Rack & Pinion and Scotch Yoke quarter turn air actuators provide a simple and reliable method of automating butterfly valves. Actuators are available in spring return or double acting. Spring return actuators use air pressure to open and springs to close the valve (failsafe). A double acting air actuator uses air to open and air to close.
Butterfly valves are used to control flow in a pipe line. Rotating a disc within the valve body 90° opens or closes the flow passage. The butterfly valve can be operated with the 10-position locking hand lever. Butterfly valves are mounted between two pipe flanges for easy installation and maintenance.
