Product Feature:
Pressure seal design.
Unique cage unit: entire seat-hinge-pin-disc assembly can be tested outside the valve before seal welding into the body. Eliminates pin seal leakage.
Easy in-line service.
Efficient operation. The hinge pin located near the center of gravity allows the conical seating face of the disc to move out and into the seat rapidly without sliding or wear. The disc pivots through a small arc preventing backflow and "water hammer".
Superior tightness: conical, lapped-in hardfaced seating is self-aligning. Valve can be used even in vertical piping with flow up.
