Bellows stop valve continues to be durable

Through automatic seam welding, a metal barrier is formed between the fluid medium and the atmosphere to ensure zero leakage of the valve stem. The inside of the shut-off valve adopts a bellows structure, and the lower end of the stainless steel bellows is welded on the valve stem to prevent the process fluid from eroding the valve stem. The other end is placed between the valve body and the valve cover to form a static seal. Double seal design If the bellows fails, the stem packing will also avoid leakage. The bellows is welded to the valve stem to maintain stable running performance and avoid the valve stem vibration caused by the valve plug vibration. A variety of product designs, can provide non-return function, adjustment function, anti-impurity function, signal feedback function, extension rod function, hand wheel locking function.
The tube stop valve is a special bevel seal design that provides excellent sealing performance, so when the valve is closed, pressure must be applied to the valve flap. The double stuffing box provides absolute safety (according to the use of DIN 4754 heat transfer oil) to force the seal The face is guaranteed not to leak. At high temperatures, the stem does not come into contact with the media, ensuring reliable valve stem operation, lubricated threaded devices for continued stability in dirty or hot and cold environments, and fine thread design for precise and reliable rotation adjustment
