Resilient Seated Ductile Iron Gate Valve

Gate Valve Set Design:        

Gate valve seats are available either integral with the valve body or in seat ring-type construction. Integral seats have the same construction material as the valve body. A pressed-in or threaded-in seat permits variation. Seat ring construction provides seats, with threaded into position or are pressed into position and seal welded to the valve body.

Small, forged steel, gate valves have hard-faced seats pressed into the body. In some series, this type of valve available in sizes from 1/2 to 2 inches rated for 2500 psig steam service. In large gate valves, discs are often of the solid wedge type with seat rings welded in, pressed in, or threaded in. Screwed in the seat rings are considered replaceable since they may be removed and new seat rings installed.
