Product Name: lined plug valves Model: 16C Specifications: DN15 to 250 belongs Series: fluorine valve Product Description: lined plug valves with through hole cock as the opening and closing parts, to achieve closure by cock spin move valve has good sealing performance, long service life, and out of the end seal at the same time. Structural characteristics: 1, the valve inlet and outlet window designed for dual-channel the grooved sealing ring structure, cocks during rotation, the seal between the sealing vice than the pressure gradually change until it reaches the fully open or fully closed position, the resulting adequate sealing pressure, sealing Vice achieve zero leakage. 2, double grooves sealing ring that can make a solid PTFE bushing in the valve body does not produce displacement, but also absorption due to temperature changes caused by deformation of the bush trace while wiping action between the bush and the cocks have a strong, to improve the life of the sealing surface. 3, the Serbian Ministry of the shaft using a PTFE diaphragm and O-ring and adjust the gasket combinations that can be adjusted between the sealing surface of the sealing pressure than the plug rotating flexible, and can ensure the sealing of the inlet and outlet end and the flange connection end . 4, the entire sealing process can be approximated that has nothing to do with the pressure in the pipeline. PTFE bushing, according to temperature and working medium with different filler material, lubrication, long life.
