About Duplex Stainless Steel Globe Valve

Duplex Stainless Steel 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

Exceptional Corrosion Resistance and Versatility

Engineered from duplex stainless steel grades, this globe valve withstands harsh industrial environments, providing reliability in the presence of chemicals, steam, water, and oil. The robust construction ensures excellent longevity and minimal maintenance, making it perfect for refineries, chemical plants, and oil & gas installations.

Precision Control and Flexible Installation

Designed to the ASME and API standards, the valve offers precise fluid regulation through handwheel operation. With flanged, butt weld, and socket weld connection options, installations are seamless across new and existing pipelines. Its bidirectional flow capability maximizes operational flexibility.

FAQ's of Duplex Stainless Steel Globe Valve:

Q: How does the duplex stainless steel material benefit the globe valve's performance?

A: The use of duplex stainless steel (ASTM A182 F51, F53, F55) delivers superior corrosion resistance, mechanical strength, and durability, making the valve suitable for a wide variety of demanding industrial applications and extending its service life.

Q: What industries and applications are suitable for this globe valve?

A: Ideal for industrial piping, oil & gas, chemical plants, and refineries, the valve is designed to handle water, oil, gas, steam, and various chemicals under diverse temperatures and pressures.

Q: When should I choose a globe valve with an Outside Screw & Yoke (OS&Y) design?

A: Select an OS&Y globe valve when you require visible verification of valve position, enhanced packing protection, and simplified maintenance-particularly valued in safety-critical and process-intensive environments.

Q: Where can this valve be installed in a pipeline system?

A: This globe valve can be installed in pipelines requiring flow regulation and shut-off, utilizing flanged, butt weld, or socket weld connections, compliant with ASME standards, and accommodates sizes from DN15 to DN300.

Q: What is the process for ensuring leakage control and pressure integrity in this valve?

A: The valve undergoes rigorous testing as per API 598 standards, with leakage class and test pressures carefully validated to ensure reliable sealing, whether using PTFE or metal-to-metal seat designs.

Q: How is flow direction managed in this globe valve?

A: With its bidirectional flow design, the valve is capable of controlling media movement in both directions, providing operational flexibility without compromising performance.

Q: What are the main benefits of choosing this valve for industrial operations?

A: Key benefits include exceptional reliability in corrosive environments, compliance with global standards, flexibility in installation and operation, and robust performance across a broad temperature and pressure spectrum.
