About Class 150 Globe Valve

Class 150 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

Robust Construction for Demanding Applications

Built with materials including ASTM A216 WCB, CF8, and CF8M, this globe valve is engineered for strength and longevity. Its flanged RF/FF ends and bolted bonnet enhance sealing and overall durability, making it ideal for industrial, chemical, petrochemical, and HVAC sectors. The polished or painted finish provides additional rust resistance, extending the valve's service life even in harsh conditions.

Optimal Flow Control and Versatile Operation

Designed with a unidirectional flow path and rising stem, the valve offers precise modulation of water, oil, gas, or steam media. The option for renewable or integral seats, as well as stainless steel or alloy trims, allows customization for specific industry needs. The manual handwheel operation ensures easy control, while the PTFE or graphite packing assures reliable sealing against leakage.

Stringent Standards and Reliable Performance

Compliant with ANSI B16.34, ASME B16.5, and tested per API 598, every valve is engineered for quality and safety. Its Class VI shut-off rating guarantees minimal leakage, suitable for high-pressure and high-temperature services. The globe valve's design meets international face-to-face standards (ANSI B16.10), ensuring seamless replacement or integration into existing systems.

FAQ's of Class 150 Globe Valve:

Q: How should the Class 150 Globe Valve be installed and operated?

A: Installation involves connecting the flanged ends to matching ASME B16.5 pipe flanges, ensuring proper gasket placement and secure tightening of flange bolts. The valve is operated manually by turning the handwheel, which raises or lowers the stem to regulate flow. Always check the flow direction arrow for correct orientation and ensure it is unidirectional as per design.

Q: What media can the Class 150 Globe Valve handle?

A: This valve is suitable for regulating the flow of various media such as water, oil, gas, and steam. Thanks to its robust construction, stainless steel or alloy trim, and high-quality sealing, it can operate reliably under high pressure and temperature conditions found in industrial, chemical, petrochemical, and HVAC applications.

Q: When is it recommended to use a renewable seat versus an integral seat?

A: A renewable seat is beneficial in applications where seat wear is common, as it allows for easier replacement and lower maintenance costs. Integral seats are ideal for lower maintenance situations and when the process fluid is less aggressive, providing a simpler design with fewer replacement parts.

Q: Where is the Class 150 Globe Valve commonly used?

A: This valve is widely used in industrial settings, including chemical plants, petrochemical facilities, and HVAC systems in India and globally. Its ability to handle high temperatures and pressures makes it suitable for a variety of applications requiring tight shut-off and reliable flow control.

Q: What is the testing process for the Class 150 Globe Valve?

A: Each valve undergoes rigorous hydrostatic testing according to API 598 standards. This ensures the valve body and seat can withstand the designated pressure (150 PSI) without leaking, guaranteeing Class VI tight shut-off performance and operational safety.

Q: How does the bonnet type affect the valve's maintenance?

A: The bolted bonnet design provides secure closure while allowing for straightforward disassembly. This makes inspection, maintenance, and seal or packing replacement easier compared to welded or pressure-seal bonnets, minimizing downtime.

Q: What are the key benefits of using this globe valve in high-pressure environments?

A: Key benefits include reliable, tight shut-off due to Class VI leakage rating, corrosion resistance provided by high-quality body materials and finishes, and the ability to maintain performance under variable pressures and temperatures. Its modular design with replaceable parts ensures consistent operation and extended service life.
