Globe valves are linear motion closing-down valves that are used to start, stop, or regulate flow using a disc as the closure element.
Globe valves are ideally suited for restricting and regulating fluid flow and are typically utilized in small-diameter pipelines. In general, globe valves are utilized for pipes with a diameter of 8 inches or less.
The following are the parts that make up a typical globe valve:
- Valve Body: Globular shape
- Disc or Plug
- Gland bushing and flange
- Seat ring
- Yoke Sleeve
- Gland Bolts and Nuts
- Handwheel: Mechanical Actuator
- Back Seat
- Pressure Seal Gasket
Numerous varieties of globe valves are intended to accommodate a wide array of tasks at the lowest possible cost. The three most prevalent configurations of globe valves available for industrial usage are:
T- type globe valves have the lowest flow coefficient and the highest pressure drop of all valve types. Such globe valves can be employed in applications requiring severe throttling.
Y-type globe valves can be cracked open for extended periods of time without experiencing serious degradation. They offer relatively low flow resistance.
Angle valve: Without the use of an elbow, these globe valves guide the fluid flow in a perpendicular direction. Because of their capacity to withstand the slugging effect, globe valves of the angle type are employed for pulsing flow services.
The globe valve has a high capacity for sealing. OBAID MASOOD provides a large variety of globe valves for different applications.
If the flow resistance from the convoluted flow route of these valves is acceptable, they can be employed for on-off duty. Some globe valves are also built with low flow resistance for usage in on-off applications
