The main features

The opening and closing parts of American standard flanged gate valve are gate plates. The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and closed, not adjusted and throttled. The gate has two sealing faces. The most common model gate valves have two sealing faces that form a wedge. The wedge Angle varies with valve parameters. Wedge gate valve disc can be made into a whole, called rigid gate; It can also be made into a gate that can produce slight deformation to improve its technology and compensate for the deviation of sealing face Angle in the process of processing. This gate is called an elastic gate.
