Butterfly Valves

All butterfly valves shown are available with actuators.

 Butterfly valves are used for applications when a short layout length is desirable and the valve is not used for precise flow regulation.  The ability of the valve to be mounted between the piping flanges allows a large diameter valve to fit in a small amount of space.  This type of valve will give a positive - leak type sealing.     Butterfly valve can be easily actuated with electric or pneumatic actuators.
