Forged steel flange connected gate valve

Z41Y forged steel flange gate valveProduct Introduction:

forged steelflangegate valveApplicable toClass150～2500LBWorking temperature-29～425℃ (carbon steel) or -29～500On small-diameter pipelines made of stainless steel at ℃, it is used to cut off or connect the medium in the pipeline. Different materials are selected and can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing media, urea, etc. It is widely used in oil pipelines.

forged steelflangegate valveWorking Principle:

forged steelflangegate valveThere are three types of body cover connection design forms. *The type is the body cover bolt connectionForged steel gateThe valve, designed in this connection form, has a valve body and valve cover connected by bolts and sealed with wrapped gaskets, which has the advantage of being easy to maintain. The second type of welded connection forged steel gate valve is designed according to this connection form. The valve body and valve cover are fully welded and sealed, with the advantage of no external leakage. The third type is a pressure self tightening forged steel gate valve with a valve cover. Valves designed in this connection form have a threaded connection between the valve body and the valve cover, and are sealed with an internal pressure self sealing ring. The advantage is that the higher the internal pressure, the better the sealing performance.

Z41Y forged steel flange gate valveProduct Features:

Adopting a pressure self tightening seal, the valve body branch pipe is welded at both ends.

The sealing surface of the valve seat and valve disc is made of cobalt based hard alloy plasma spray welding, which has good wear resistance and abrasion resistance.

The valve stem has undergone anti-corrosion nitriding treatment, which provides good corrosion resistance and abrasion resistance.
