Y-Type Globe Valve Manufacturer and Supplier in India
Speciality Valve is a Y-Type Globe Valve Manufacturer and Supplier in India, producing high-performance valves designed to handle high-pressure and high-temperature service. Our Y-pattern globe valves reduce pressure drop with an angled seat design, making them ideal for applications requiring efficient throttling, isolation, and long service life.
Function & Working
Y-type globe valves operate by moving a disc perpendicular to the flow path but angled at approximately 45°. This Y-shaped body design minimizes flow resistance and reduces energy loss compared to conventional globe valves. They are widely used in pipelines where pressure drop must be minimized while still requiring tight shutoff and precise throttling.
Advantages of Y-Type Globe Valves
Lower pressure drop due to streamlined Y-pattern body
Suitable for throttling, regulating, and isolation duties
Compact construction for high-pressure and high-temperature service
Available in forged or pressure-seal bonnet options
Reduced erosion on seats and longer service life
Compliant with API, ASME, and BS standards
