Gate valve:

Gate valve is also called the gate valve, gate valve is widely used. Opening and closing is a gate valve, gate valve is ram, ram movement direction and perpendicular to the direction of flow of a gate can only be fully open and close.

The advantages of gate valve:
1. small fluid resistance, and sealing surface of erosion and erosion by the medium is small too.
2. save Labour to open and close, apply pressure and temperature range is wide.
3. medium flow unrestricted, non-spoiler, do not reduce the pressure.
4. the structure of the form is simple, short length, good manufacturing technology, wide application scope.
5. compact structure, flexible operation of the light, good rigidity, smooth channel, number of flow resistance is small.
6. light weight, made from ontology with forging (casting), easy installation and maintenance.
7. reliable sealing performance.
8. long service life, the sealing surface of stainless steel and carbide.

The principle of gate valves:
Closure principle is gate seal face is consistent with the height of valve sealing surface smooth, level off, fit each other, it plays a role of cutting mainly in the line.
