Soft sealing plug valves commonly used in harsh environments such as corrosive, highly toxic and hazardous materials, strictly prevent leaks occasions, and the valve material will not pollute the medium of the occasion. The valve body can be selected according to the working medium carbon steel, alloy steel and stainless steel. A. According to the use of temperature and working medium using F4, F46, PVDF, PP, PO, PE and other self-lubricating material bushing, lubrication, the whole process of sealing friction coefficient is small, plug body flexible operation, long service life . B. The valve body inlet and outlet end window design and dual groove seal ring structure, the cock in the rotation process, the sealing pressure between the sealing pressure is gradually changing until it reaches full open or fully closed position, to produce adequate sealing Pressure than the seal to achieve zero leakage. C. Dual groove seal ring can not only make the sleeve stable in the valve body does not produce displacement, but also absorb the temperature changes caused by the liner caused by micro deformation, while producing strong friction between the bushing and the cock, with automatic cleaning Role, improve the sealing surface of the service life. D. plunger at the top of the unique anti-lip seal design, the use of a soft seal material diaphragm and the metal diaphragm and adjusting the gasket combination can both adjust the seal than the pressure between the sealing surface, so that plug rotation flexibility, but also to ensure that into, Seal the outlet and center flange connections. E. Suitable for high erosion gas-solid. Liquid-solid media. Such as PVC, urea, the anhydride, caustic soda production facilities, or external media require high leakage, such as HF, phosgene and so on. F. medium can flow in both directions, the installation direction is unrestricted, online maintenance, more convenient to use G. unique design to prevent static electricity, fire safety, safe to use.
