Advantages of gate valves
1. Low fluid resistance
2. The torque required for opening and closing is small
3. Ring network pipeline suitable for medium flow in two directions
4. The fully open sealing surface is less eroded by the working medium than the globe valve
5. The shape and structure of the valve body are relatively simple, and the manufacturing process is better
6. Relatively short structural length
Features
1. Open degree can be indicated in distance, in case to close.
2. 100% Sealing performance with zero leak.
3. Easily maintenance.
4. Anti vibration & anti-cavitation.
