ANSI Design Gate Valve

ANSI Design Gate Valve

The movement direction of the gate is perpendicular to the fluid direction, the gate valve can only be fully open and closed, and can not be adjusted and throttled. The gate has two sealing surfaces, and the two sealing surfaces of the most commonly used mode gate valve form wedges. The cuneiform angle varies with the valve parameters, usually 5 °, and 2 °52 when the medium temperature is not high. The gate of the wedged gate valve can be made into a whole, called a rigid gate, or it can be made into a gate that can produce a small amount of deformation to improve its workmanship and make up for the deviation of the angle of the sealing surface in the machining process. This gate is called an elastic gate.
