Cast Steel Gate Valve
Rising-stem cast steel gate valves are used when it is important to know by immediate inspection whether the valve is open or closed and when the threads (stem and gate) exposed to the fluid could become damaged by fluid contaminants. In this design, the stem rises out of the gate valve when the valve is opened.
The wedge gate of the gate valve provides tight sealing even at low differential pressure. Grooved wedge guided and fitted by body, assures proper and consistent seal regardless of valve position, and also minimizes seat wear and damage, since seating surfaces of the wedge and seat are in contact during less than 5% of the total wedge travel.

Features of Cast Steel Gate Valves:
Bolted bonnet
Outside screw and yoke
Rising stem and non-rising handwheel
Flexible wedge, fully guided
Metal-to-metal seat
Renewable seat ring and stem backseat
Manual operation standard, gear operator and actuation available
Butt weld end
Flange end: Raised face or ring type joint
