Ansi Class 300 Control Bellow Seal Globe Valve SS 304 Cryogenic Globe Valve

Stainless steel flange ends type globe valve

Flange Globe valves offer the ultimate in dependavle service for steam, air, gas, oil , oil vapor and high pressure in stallations. All have streight-though ports to assure minimum turbulence, erosion, and resistance to flow. They are available in a wide variety of trims.

1 . Body: Body is cast with heavy sections reinforced at points subjected to the greates stress.

2 . Disc: Disc is plug type.

3 . Stem: The Tee-head disc-stem connection prevents lateral strain on the stem for smooth, easy operation.

4 . Bonnet Gasket: Bonnet gasket provides a positive seal against leakage. PN16 to PN40 valves have a male/Female bonnet joint. A ring type gasket is employed in PN63 to PN100

5 . Operator: Handwheel, Gear Box, Pneumatic, Electric Acutator

Application

The globe valve, also called the door, is the most widely used type of valve. It is popular because of the small friction between the sealing surfaces during the opening and closing process. It is relatively durable, the opening height is not large, and the manufacturing is easy. Convenient, not only for medium and low pressure, but also for high pressure.Depending on the form of movement of the flap, the change in the seat opening is proportional to the flap travel. Due to the relatively short opening or closing stroke of the valve stem of this type of valve, and the very reliable cutting function, and because the change of the valve seat opening is proportional to the stroke of the valve flap, it is very suitable for the adjustment of the flow rate. Therefore, this type of shut-off globe valve is well suited for shut-off or regulation and throttling.The valve plays an important role in the cutting and throttling of the medium in the pipeline in which it is located. The shut-off valve is an extremely important type of shut-off valve. The seal is applied by applying torque to the valve stem, and the valve stem is oriented in the axial direction. The flap exerts pressure so that the disc sealing surface fits snugly against the seat sealing surface, preventing the medium from leaking along the gap between the sealing faces.
