Gate Valves

China industrial gate valves are used to cut off or connect media transmission, and are suitable for pipeline systems in petroleum, chemical, thermal power plants and other industrial fields. Gate valves can only be fully opened and disconnected in the pipeline, which means it cannot be used for regulation and throttling. Gate valve provides well on/off or shuts off features, pressure drop during operation is very less, and is bidirectional. Meanwhile as metal to metal seat, these different types of gate valves can respond to specific operating high pressure, high temperature operating conditions.

Industrial Gate Valve Advantages

1. Flexible or solid wedge

2. Full-bore or reduced-port

3. Replaceable seat or integral seat

4. Bolted bonnet or self sealing bonnet

5. Rising Stem

Rising stems are fixed to the gate and they rise and lower together as the valve is operated, providing a visual indication of the manual regulating valve position and making it possible to grease the stem. A nut rotates around the threaded stem and moves it. This type of valve has an inside screwed stem and the packing is subjected to wear because of the up and down movement and turning motion of the stem.
