Lined Butterfly Valve

Extensive field research and engineering have developed this state-of-the-art design which provides excellent shutoff protection (bubble-tight shutoff) and high Cv values. The Series 22/23 resilient seated butterfly valve is crafted in a variety of materials such as PTFE, PFA, Stainless Steel, UHMWPE and special alloys to fit a wide range of customer requirements. As with all Bray's products, precision manufacturing and exceptional quality remain the keys to a proven record of long service life.

Seal Capsule

(Secondary Seal) This seal capsule fully isolates the valve body and stem from the line media. The Seal Capsule is made of a virgin PTFE enclosing the internal energizer. The capsule fits into grooves in the upper and lower disc hubs. When compressed between the disc and seat during assembly, the capsule becomes energized, exerting both upward and downward pressure on disc and seat surfaces.

Body Seals

(Bidirectional): Reinforced PTFE gaskets are placed between the body halves. These seals eliminate contamination from external environmental conditions and potential leak path from the line media.
