Class 900 Globe Valve

About Class 900 Globe Valve

Class 900 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

Designed for High Pressure and Temperature

Engineered to handle pressures up to 2220 psi (153 bar) and temperatures ranging from -29C to 425C, this Class 900 Globe Valve is suitable for rigorous industrial environments. Its robust construction from forged carbon steel or stainless steel and compliance with ASME B16.34 ensures dependable service in demanding conditions.


Versatile Connection and Operation Options

Offering flexibility, the valve can be fitted with either RF/RTJ flanged or butt weld end connections to match installation requirements. Handwheel operation with a rising stem provides precise throttling capability, ideal for flow regulation in crucial pipeline systems.


Stringent Compliance and Quality Assurance

Manufactured to API 623/BS 1873, and tested following API 598 standards, each valve is available with third-party inspection certification. The fire-safe design enhances operational safety, while the stellite overlay seat and graphite packing contribute to a leak-tight, long-lasting seal.
