5 Inch Gate Valve

5 inch Gate valves are widely used in corrosive fluid, gas, powder pipelines, such as drainage, sewage treatment, construction, industrial environmental protection, food production, medicine, chemical industry, papermaking, shipbuilding, petroleum and other industries. The main function is to open and close or adjust.

Gate valves of different materials can also be used as marine gate valve, mechanical gate valve, natural gas gate valve.

Application of Gate valve

Gate valves are widely used in petroleum and steam pipelines such as petrochemical, thermal power plants, petroleum refining, offshore oil, water conservancy projects and sewage treatment projects. are widely used.

Gate valves have the following advantages:

① The fluid resistance is small.

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

③ The flow direction of the medium is not restricted.

④ When fully opened, the erosion of the sealing surface by the working medium is smaller than that of the globe valve.

⑤ The shape is relatively simple, and the casting process is better.

The gate valve also has shortcomings:

① The overall size and opening height are large. Installation requires more space.

② During the opening and closing process, there is relative friction between the sealing surfaces, which is easy to cause scratches.

③ Gate valves generally have two sealing surfaces, which adds some difficulties to processing, grinding and maintenance.
