Soft seal cock of the pneumatic valve

soft seal cock pneumatic valve is often used in harsh environment, such as corrosion resistance, high toxic and harmful medium, strictly banned leak, and pneumatic valve material not medium formation pollution occasion. Pneumatic valve could be selected according to the working medium carbon steel, alloy steel and stainless steel materials.
。 Can be used according to the working temperature and medium using F, F, PVDF, self-lubricating material such as PP, PO, PE liner, good lubrication, sealing in the whole working process of the pair of small friction coefficient, the plug body flexible operation, long service life.
　　B. Pneumatic valve import and export side window design and two-channel grooved ring structure, plug in the process of rotation, the seal between the sealing pressure ratio in the gradual change, until she reached full open or close position, generate enough sealing pressure, seal achieve zero leakage.
　　C. Two-channel grooved ring can make solid liner in pneumatic valve body does not produce displacement, and can absorb trace deformation caused by temperature change bushing, between liner and cock at the same time produce strong friction, with automatic cleaning function, improve the service life of the sealing surface.
　　D. Piston at the top of the unique design of the lip seal with a soft sealing material film and metal diaphragm and adjusting shim combination can adjust the seal between the sealing surface pressure, flexible to rotate the plug, and can assure you, in the outlet and the seal on flange connection.
　　E. Suitable for high scouring of gas-solid. The liquid-solid phase medium. Such as PVC, urea, this anhydride, caustic soda production devices, or external leakage demanding medium, such as HF, phosgene, etc.
　　F. Medium can be two-way flow, there is no limit on the installation direction, realize the online maintenance, it is more convenient to use the
G. Unique design can prevent static electricity, fire safety, use safety.
