Pressure Seal Globe Valve

Pressure Seal Globe Valve

A globe valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body. Globe valves are used widely, because of the relatively small friction between the sealing surface when open or closed. Also globe valves are durable, open height is small, manufacturing is easy and convenient maintenance, etc. It can be used not only in the low pressure but also high pressure. Globe valve closed depend on stem pressure, make the disc sealing surfaces and seat sealing surface tightly. To stop the flow of media, Globe valve only allowed a one-way medium flowing direction, so globe valves are installed directional. Globe valves are used for applications requiring throttling and frequent operation. For example, globe valves or valves with a similar mechanism may be used as sampling valves, which are normally shut except when liquid samples are being taken. Since the baffle restricts flow, they're not recommended where full, unobstructed flow is required.

Pressure sealed globe valve is applicable to the cutting and connection of pipelines medium that are used in various industries such as petroleum, chemical industry, pharmacy, chemical fertilizer, electric power industry etc. And its specifications can be summarized as follows:1.
