Class 150 Cast Steel Globe Valve
GLV701-150
Product Description
The disk in a flange globe valve can be out of the path of flow or close to the path of flow entirely. The disk moves normally to the seat when closing or opening the valve. The movement creates an annular area between the seat rings which gradually closes when the disc is closed. This enhances the throttling capability of the flanged globe valve which is very important for regulating fluid flow.
This valve has very minimal leakage relative to other valves like gate valves. This is because the flange globe valve has the discs and seat rings making a good contact angle which forms a tight seal against fluid leakage.

Media
Globe valves can be used for both gas and liquid systems. Globe valves are not specified for high purity or slurry systems. The valve has inherent cavities that easily promote contamination and allow slurry material to become entrapped, disabling the valve operation.
