Features
· Globe valve opening and closing parts are plug-shaped Valve flap,Seal appear before plane or cone,Valve flap do linear movement along the center line of the fluid.
· Globe Valve is only applicable to fully open and fully closed,
Not allowed to be adjusted and the throttle.
· Globe valve is mandatory sealed valve,Therefore when valve close,
Pressure must be applied to the Valve flap,To force the sealing surface does not leak.
· Medium flow of Globe Valve,from up to down, to reduce stem stress.
· globe valve is opening, valve flap opening height achieve to 25% to 30% of nominal diameter,the maximum flow rate can be achieved.
