Customized Design is negotiable.

Performance:

1. Small flow resistance. The medium channel inside the valve body is straight through, the medium flows in a straight line, and the flow resistance is small.

2. Less effort when opening and closing compared with globe valve, no matter it is open or closed, the direction of movement of the shutter is perpendicular to the direction of medium flow.

3, high height, long opening and closing time. The opening and closing stroke of the shutter is large, and the lifting is performed by a screw.

4, water hammer phenomenon is not easy to produce. The reason is the long shutdown time.

5. The medium can flow in any direction on both sides, which is easy to install. Gate valve channels are symmetrical on both sides.

6. The face to face length (distance between the two connecting end faces) is small.

7. Simple shape, short structure length, good manufacturing process and wide application range.

8, compact structure, good valve rigidity, smooth passage, small flow resistance, sealing surface using stainless steel and hard alloy, long service life, PTFE packing, reliable sealing, light and flexible operation.

Application:

petroleum, chemical, Stem, Oil, Gas, Construction, pharmaceutical, light textile, electric power, shipbuilding, metallurgy, environmental protection and energy systems
