The valve has only two moving internal parts the gate and the stem. The gate is fully supported throughout travel by an
integrally cast tongue and groove fit between it and the valve body. A dual rubber seal is formed between the rubber
encapsulated resilient wedge and the valve body to guarantee drop-tight shut-off every time. The combination of true
compression and dynamic wedging of the gate is created without harmful sliding, shearing or other wear-inducing action.
The massive vulcanized rubber seating edges on the gate self-absorb normal wear and tear, assuring a positive seal, even
after years of service. The valve will seal bubble-tight to 250 psi working pressure, with the flow in either direction and the
valve in any position. The valve features an unobstructed, thru-conduit flow path for full flow capacity. Closed, the valve
provides bottle-tight, zero leakage in either direction at full rated differential pressure with dual body gate seating.
