Oblique Type Y Type Cast Steel Globe Valves API 603 300LB 2''

Globe valves are linear motion closing-down valves used to start, stop or regulate the flow using a closure member referred as a disc. The globe valve disk can completely close the flow path or can be removed entirely. The seat opening changes proportionately with the travel of the disc which is ideal for duties involving flow regulation. Globe valves are most suitable and widely used for throttling and controlling fluid flow and are generally employed in small size piping.

A globe valve uses a linear motion for moving a disc (closure member) into or out of the seating surface. Globe Valves form a globular-shaped cavity around the port region and hence the name. The disc can be of various shapes and moves perpendicular to the globe valve seat. This disc movement helps in the valve opening and closure. Globe valves in general are used for pipes of size 8 inches or less. In this article, we will explore the globe valve types, parts, working principle, function, symbol, application, advantages, and disadvantages.

In addition, depending on the design of the seat and disc, the seating load of globe valves can be positively controlled by a screwed stem. The sealing capacity of the globe valve is high. They can be used for on-off duty if the flow resistance from the tortuous flow passage of these valves is acceptable. Some globe valves are also specifically designed for low flow resistance for use in on-off duty. Because of the short travel distance of the disc between the open and closed positions, globe valves are ideal if the valve has to be opened and closed frequently. Thus, globe valves can be used for a wide range of duties.

Description & Features:

Wye Pattern Globe valves can be cracked open for long periods without severe erosion. They offer very low resistance to flow. For start-up operations, Y-type globe valves are extensively used..

● Full Port or Standard Port.

● Seat is integral on the body,welded seat into body is available on request.

● This valve has logical structure, reliable seal, excellent performance and nice design.

● Sealing face is overlayed by STL, which is friction-resistant, corrosion resistant to ensure a long time use life.

● Stem heat-treatment and surface nit riding-treatment to ensure function of corrosion resistance and friction resistance.

● It has double seal, thus the capability is more reliable.

● The stem may show the position of lift, thus it is more clearer.
