the characteristics of the american standard plug valve
① plug valve sealing surface between the movement with a wipe effect, fully open to completely prevent the sealing surface and the media contact, it can be used for medium with suspended particles.
② plug valve cylindrical closure by rotating the 900 can be achieved on and off so the valve is very suitable for quick opening and closing of the occasion.
③ plug valve structure is simple and easy to maintain and clean, such as tight-type plug-dimensional plug, unscrew the tight nut, remove the gasket plug can be removed from the valve body, for cleaning and maintenance.
