stopcock structure features
1, the valve inlet and outlet end of the window design for the dual groove seal ring structure, the tap in the rotation process, the sealing pressure between the seal than the gradual change in pressure until it reaches the fully open or fully closed position, produce enough pressure than the seal, seal leakage reached zero. 
2, double groove seal ring that can make ptfe bushings stable in the valve body does not produce displacement, but also absorb the temperature changes caused by the liner caused by micro deformation, while the bushing and cock produce a powerful wiping effect, and improve the service life of the sealing surface. 
3, the upper part of the plug shaft with a ptfe diaphragm and o-ring and the adjustment gasket combination, which can adjust the seal than the pressure seal, the plug rotation flexible, but also to ensure that the inlet and outlet flange and the sealing end of the seal . 
4, the entire sealing process can be approximately considered that the pressure has nothing to do with the pipeline. 
5, ptfe bushing, according to the use of temperature and working medium using different materials filler, good lubrication, long life.
