“Y”- Pattern Globe Valves

Globe valves are used for flow regulation, frequent operation, increased flow resistance or for positive shutoff when closed. Globe valves are closing-down valves in which the closure member is moved squarely on and off the seat. By this mode of disc travel, the seat opening varies in direct proportion to the travel of the disc. This proportional relationship between valve opening and disc travel is ideally suited for duties involving regulation of flow rate. Globe valves can also be used for on-off duty, the seating load can be positively controlled with high sealing capacity.
The change in direction of fluid flow through these valves produces increased resistance and pressure drop. The oblique pattern globe-valve body is designed to reduce the flow resistance of the valve to a minimum. This valve combines low flow resistance for on-off duty with the robustness of globe-valve seatings. Globe valves are used in many industrial applications including the oil and gas industry, pharmaceutical, manufacturing, automotive, and marine. Globe valves are also recommended for services requiring frequent operation and positive shut off.
