Pressure Valves Globe Valves are O.S. & Y Type i.e., Outside screw & yoke, Bolted bonnet, & Rising stem. Globe valves are used where throttling and both throttling and shut-off is required. They can also be used for on-off service, but because of high pressure drop, this is generally confined to applications where the valve is normally closed and drop is not important when the valve is open. Normally globe valves are installed with flow under the disc, but under certain conditions flow over the disc may have the advantages.
Pressure Valves can also supply Angle Valves, “Y” Type Globe Valves and Globe Valves as S.D.NR (screw-down non-return) which in effect converts it into two valves – stop valve when closed or a check valve when open.
