Electric multi turn cast iron flange gate valve

The opening and closing parts of the flanged gate valve are the 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 two sealing faces of the most common type of gate valve form a wedge. The wedge angle varies with the valve parameters.
Wedge gate valves can be made into a whole body, called a 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.
