1. Reliable sealing,convenient operation,opening and closing fast.
2.The wear-resisting seat design ensures minimal seat wear and double eccentric disc design provides excellent throttling capabilities ,it has characteristic of super long usage life,frictionless closure,etc.
3.The application of self lubricated bearings.
4.Preventing the disc from closing under over/under travel by adjusting mechanical stopper.
5.Valve disc seal for replaceable designing,Valve disc seals are usually rubber ring, or metal seal ring,the seat seal material is butt - welded stainless steel or other alloy material.
