The opening and closing parts of the Cast steel gate valve   are the gate,in shape of a wedge,that's the reason that they are named as wedge gate valve.the direction of motion of the gate is perpendicular to the fluid direction. The wedge gate valve can only be fully opened and fully closed and can not be adjusted and throttled.The gate valve was designed to be used either fully open or fully closed, because due to the shape of its obturators which have the shape of a wedge, if it were operated partially open, there would be a great loss of pressure and the sealing surface will be damanged under impact of the fluid.

Cast steel gate valve,designed and manufactured according to the American standard API600,ASME B16.34, flanged end to ASME B 16.5, and tested according API598, has a specific and restricted function to release or block the flow of different types of fluids in pipelines.
