9,High precision ball& High tightness seat
10,Long life ball&seat
11,The best fire safe and static resistance safety
12,The metal to metal ball valve adopts spring seat structure, which can push upstream seat tightly against the ball surface creating a reliable seal even if extremely low pressure.
13,Valve stuck under high temperature preventedIn case of high temperature working condition, the valve seat and ball would possibly get stuck due to heat expansion, and the valve could not be open. Our metal to metal seated ball valves employ the design of beveling spring loading, which would absorb the heat expansion of parts caused by the beveling spring. Then, it is ensured that the valve would not get stuck and realize easily open and close in case of high temperature condition.
