HS20手动衬胶蝶阀
Extensive field research and engineering h*e developed this state-of-the-ar*sign which provides excellent shutoff protection (bu*le-tight shutoff) and high Cv values. The Series 22/23 resilient seated butterfly valve is crafted in*ariety 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.
(Secondary Seal) This seal capsule fully isolates the valve body and stem from the line media. The Seal Capsulde of*irgin PTFE enclosing the internal energizer. The capsule fits i* 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.
(Bidirectional): Reinforced PTFE gaskets are placed between the body halves. These seals eliminate contamination from external environmental conditi* and potential leak path from the line media.
