Features:

1, valve bottom sets, facilitating sump clean dirt gently, and can smoothly through pipe sweeper.

2, stem with large guide programs, can obtain rapid threaded transmission lifts.

Three, adopting friction power tiny, can automatic lubrication, and resistance to gas and various corrosion gas high-performance packing, flexible operation, reliable sealing.

4, good sealing, operation can be eradicated maintains tight sealing surface dirt, the seal.

5, fluid resistance small. Gate valve body internal medium channel is gold, medium flows through gate without changing its flowing direction when flow resistance, so small.

6, opening and closing more effort. Open-close direction and the media when disc movement in vertical flow direction. Compared with the globe valves, gate valves closing of relatively maintenance free.

7, medium flow direction generally not restricted. Medium can be any direction from gate sides can be obtained through, the purpose of connected or truncation. Installation convenient, applicable to flow direction of medium in pipelines impossible to change.
