Wedge gate has three types of construction:
The structure of single gate is simple, but the machining precision of wedge Angle is high.
The structure of double gate requires lower precision of wedge Angle, and it is not easy to die of wedge, but the structure is more complicated. Genius valve
Flexible gate has the advantages of single gate and double gate, and can avoid their disadvantages, so it is widely used. It is characterized by an annular groove around the gate to give the gate proper elasticity. Parallel gate valves usually adopt double gate structure;
Special purpose gate valves, such as large bore valves for long distance oil and gas pipelines, have a single gate structure for cleaning valves and pipelines.
