Welded Bonnet Globe Valve

Welded Bonnet 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.

Provided Welded Bonnet Globe Valve is made of cast alloy steel/cast carbon steel/cast stainless steel. Testing standard of this valve conforms to API 602/API 598/BS 5352 norms. Design standard of this valve is in sync with BS 5352/API 602 specifications. This valve can be availed with butt-weld/flange/NPT/socket weld end connection based design. Size of this Welded Bonnet Globe Valve ranges between inch to 2 inch. Quality of this valve has been verified on the basis of its design precision, longevity, material choice etc.

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
