Advantage

1. Low fluid resistance.

2. The external force required for opening and closing is small.

3. The flow direction of the medium is not restricted.

4. When fully open, the erosion of the sealing surface by the working medium is smaller compared with globe valve.

5. The shape is relatively simple and the forging process is good.

Disadvantages

1. During the opening and closing process, there is relative friction between the sealing surfaces, which can easily cause scratches.

2 Forged steel gate valves generally have two sealing surfaces, adding some difficulties to processing, grinding and maintenance

Application

Oil, Petro industry, Steam, gas
