Gate valve bodies are made from many different materials such as cast iron gate valves, stainless steel gate valves, copper gate valves, and steel gate valves. Additionally the valve body can be connected: Threaded, Welded  or Keyed

- Valve gates are 2 flanges connected to the pipeline by bolt holes and locating screws. Gaskets and gaskets are inserted between the two flanges of the pipe and valve to seal the two ends together.

- The valve cover located at the top can be opened to replace or maintain the valve disc. This position has a small hole for the valve stem to penetrate straight through. There are many types of gate valves, so the valve cover is assembled by flange, thread, or welding.

-  Handwheel, Valve Shaft, Valve Disc are a chain linked together in a straight line and located in the valve body. The crank position on top is connected to the valve shaft in the middle and finally the valve disc below. When turning the steering wheel clockwise, this chain will pull the valve stem up and vice versa. Therefore, the Open/Close phenomenon appears at the valve.
