Previous: Throttling Globe Valve
Flanged globe valve is widely utilized for pipelines to connect or cut off medium in petroleum, electricity, metallurgy, etc. Flanged globe valve allows medium to flow in only one direction. So the flow direction of medium should be focused when using API globe valve. Flanged globe valve is produced in accordance with API standard in designing, manufacturing and inspection.
