The opening and closing parts of fluorine lined globe valve are plug-shaped disc, the sealing surface is flat or conical, and the valve disc moves in a straight line along the center line of the fluid. The movement forms of the valve stem include the lifting rod type (the valve rod rises and falls, and the hand wheel does not rise and fall), and there are also the lifting and rotating rod type (the hand wheel and the valve rod rotate and lift together, and the nut is set on the valve body). The globe valve is only suitable for full opening and full closing, and adjustment and throttling are not allowed.

Fluorine lined globe valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak. When the medium enters the valve from the lower part of the valve disc, the resistance to be overcome by the operating force is the friction force between the valve stem and the packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the diameter of the valve stem should be larger, otherwise the valve rod bending fault will occur. After the appearance of self sealing valve, the medium flow direction of the stop valve changes from the top of the valve disc into the valve chamber. Under the action of medium pressure, the force to close the valve is small, but the force to open the valve is large, and the diameter of the valve stem can be reduced accordingly. At the same time, under the action of medium, this type of valve is also more tight.We insist on offering high-quality production with great enterprise concept, honest product sales and also the finest and fast service. it will bring you not only the superior quality solution and huge profit, but the most significant should be to occupy the endless market for ODM Supplier China JIS ASME Wafer Lug Flange Knife Gate Valve OS&Y or Nr Handwheel Pneumatic Soft Seal Hard Seal Wcb Ss Globe Valve, We hope to ascertain far more small business interactions with prospects all over the world.
