SQK Flexible Wedge Globe Valve

About SQK Flexible Wedge Globe Valve

Flexible Wedge Globe Valve

The BS 1873 Globe Valves is exceptionally sturdy, rugged and durable, with a reputation for quality, integrity and long service.

They are designed for tight sealing and ease of operation. The valves are available flanged & butt-weld ends in pressure rating from ASME Class 150 to Class 2500, and in a variety of materials of construction.

 Globe Valves feature a ball-type disc, outside screw-and-yoke and bolted-bonnet construction. They conform to BS 1873 and also meet the general requirements of API 600, including shell wall thickness and stuffing box dimensions.

Cast steel ASME B16.34 T Type & Y Type Globe Valves Pressure Seal Bonnet design  

The ASME B16.34 series of T Type & Y Type Globe Valves features a pressure seal bonnet design for high pressure services. These valves are extensively used in high pressure and high temperature steam, oil, gas, chemical and water applications in thermal power plants, fertiliser plants, petrochemical plants and refineries. These valves are available in butt weld ends in pressure ratings of Classes 900, 1500 and 2500, and come in carbon steel and alloy steel construction.

 

Cast Steel Cryogenic Globe Valves

Specially-adopted, extended-bonnet globe valves provide the right solution for such low-temperature and cryogenic services. We offer a range of globe valves (as well as check valves) for low temperature and cryogenic services, used in processing, storage and transportation of liquefied gases such as Ethylene, LPG,LNG, Hydrogen, Helium, Oxygen, Nitrogen and Argon. Low temperature services of up to -460 C are covered by low-temperature carbon steels like LCB and LCC materials. Cryogenic Globe Valves are available in ASME Classes 150 to 1500. Extended Bonnet Optional extended bonnet with vapour column length according to BS 6364 and / or customer specifications will be provided

Advanced Valve Design for Maximum Reliability

The SQK Flexible Wedge Globe Valve utilizes a straight-pattern body and flexible wedge, ensuring enhanced sealing and better alignment under varied operational conditions. This flexible wedge minimizes seat damage and leakage, even after prolonged cycling or temperature changes.


Versatile Application Across Multiple Industries

Designed to handle water, oil, gas, and steam, this globe valve is suitable for numerous industrial processes. Its compatibility with different end connections (flanged RF, RTJ, or butt weld) and wide material availability make it ideal for process flow control in power plants, refineries, and general industry.


Engineered for Durability and Compliance

Manufactured to BS 1873, DIN, and ASME standards, the valve undergoes rigorous hydrostatic testing per API 598. An epoxy coating protects the robust body from corrosion, extending operational life even in severe environments. With a temperature rating up to 200C and multiple pressure classes, it guarantees reliable service.
