Applications Of globe Valve Zero Leakage Globe Valve

Main features:

Globe valve   is different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug and a ring seat in a generally spherical body. The flow direction from bottom to top is important when installing the valves.

 When medium by disc below into the valve 6, the operating force needed to overcome the resistance, is stem and packing of the friction force and the thrust produced by medium pressure, close the valve strength is stronger than open the valve, so it's bigger, the diameter of the stem or stem top bending failure happens. In recent years, from the valve seal, flange globe valve is replaced by the disc above the medium flow direction into the valve cavity, in the medium pressure at this moment, close the valve of the force is small, and the strength of the valve, the valve stem diameter can be reduced accordingly.
