Electric shut-off valve

The electric shut-off valve and the flange gate valve are the same type of valve, which consists of an electric actuator or a pneumatic actuator and a shut-off valve. The difference between the closing member and the shut-off valve is that the valve body rotates around the center line of the valve body. A valve that opens and closes.

The electric shut-off valve and the flange gate valve are the same type of valve, which consists of an electric actuator or a pneumatic actuator and a shut-off valve. The difference between the closing member and the shut-off valve is that the valve body rotates around the center line of the valve body. A valve that opens and closes. The gate valve is mainly used in the pipeline to cut, distribute and change the flow direction of the medium. Two-piece ball valve, three-piece ball valve, is a new type of valve that has been widely used in recent years.

 

  advantage:

 

  1. Simple structure, convenient manufacturing and maintenance.

 

  2. The working stroke is small and the opening and closing time is short.

 

  3, good sealing, small friction between sealing surfaces, long life.

 

  4. The structure of the shut-off valve body is straight-through, direct-flow and right-angle. Straight-through is the most common structure, but its fluid resistance is greatest. DC fluid resistance is small, and it is mostly used for fluids containing solid particles or high viscosity. The right angle valve body is mostly forged, suitable for small through, high pressure shut-off valves.

 

  5. The frictional force of the sealing surface is smaller and more wear-resistant than the gate valve during the opening and closing process.

 

  6, usually only one sealing surface, good manufacturing process, easy to repair.

 

  7, electric actuator is easy to operate.
