CF8 RS Rising Stem Resilient Seated Gate Valve For Water Pipeline Use
Product Introduction:
A gate valve is like a gate, with the movement direction perpendicular to the direction of the fluid, and gate valve can only be fully open and closed, not adjusted or throttled.
Gate valve with following working principle: turn the hand wheel to open and close the valve plate connected to the stem by the hand wheel and stem thread advance, back, lift or drop, very easy operation.
stainless steel gate valves with meticulous and wide raw material selection in accordance with relevant domestic and international standards, and the overall quality of the materials is high, stainless steel 304 and stainless steel 316 are most commonly used raw material for stainless steel gate valve products.

Product features:
1. Simple shape, good manufacturing process, and wide applicability.
2.Low flow resistance, the medium channel inside the valve body is straight, and the medium flows in a straight line, resulting in low flow resistance.
3 When opening and closing, it is more labor-saving. Compared with globe valves, the direction of gate movement is perpendicular to the direction of medium flow, whether it is open or closed.
4. The medium can flow in any direction on both sides, making it easy to install. The two sides of the gate valve channel are symmetrical.
5. The flow direction of the medium is not restricted, does not disturb flow, and does not reduce pressure
6. The structural length (the distance between the two connecting end faces of the shell) is relatively small, longer close time, not easy to occur water hammer phenomenon.
7.Compact structure, good valve rigidity, smooth channel, small flow resistance, sealing surface made of stainless steel and hard alloy, long service life, using PTFE packing. Reliable sealing, easy and flexible operation
8.advanced and reasonable sealing raw material, the sealing surfaces of the gate and valve seat are made of Stellite cobalt based hard alloy with 9.different hardness by welding, it is reliable, hard, wear-resistant, high-temperature resistant, corrosion-resistant, with good scratch resistance and long service life.
10.The valve stem has undergone quenching and surface nitriding treatment, which provides good corrosion resistance, scratch resistance, and wear resistance.
11.Adopting a wedge-shaped elastic gate structure, with thrust bearings installed on medium and large diameters, the friction force is small, and it is equipped with manual impact, making it easy to open and close.
Meets the requirements of advanced domestic and international standards, with reliable sealing, excellent performance, and beautiful appearance.
