Butterfly Valves

The FLSmidth Butterfly Valve has many unique features into the valve, resulting in longer service life, greater reliability, ease of parts replacement and interchangeability of components. 

One of the valve's key elements is the unique tongue-and-groove seat design. This resilient seat features lower torque than many valves on the market today and provides complete isolation of flowing media from the body. The tongue-and-groove seat to body retention method is superior to traditional designs, making field replacement simple and fast. The seat is specifically designed to seal with slip-on or weld-neck flanges. The seat features a molded O-ring which eliminates the use of flange gaskets. An important maintenance feature is that all resilient seats for FLSmidth butterfly valves are completely interchangeable.
