American standard electric gate valve
1. Fluid resistance is small, and its resistance coefficient is equal to the pipe segment of the same length.
2. Simple structure, small volume, light weight.
3. Close and reliable. At present, the sealing surface material of gate valve is widely used plastic, good sealing, and has been widely used in vacuum system.
4. Easy to operate, quick to open and close, from full open to full close as long as the rotation of 90°, easy to remote control.
5. Convenient maintenance, gate valve structure is simple, sealing ring is generally active, disassembly and replacement are more convenient.
6. When fully open or fully closed, the sealing surface of the ball and the seat is isolated from the medium, and the medium will not cause the erosion of the sealing surface of the valve when the medium passes.
7. Wide range of application, diameter from small to a few millimeters, to a few meters, from high vacuum to high pressure can be applied.
American standard ball valve according to its channel position can be divided into straight-through, three-way and right-angle. The latter two gate valves are used to distribute the medium and change the flow direction of the medium.
1. Keep the valve stem in a rotating position.
2. Cannot be used as a throttling.
The ball valve with transmission mechanism should be installed upright.
