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

Superior Corrosion Resistance

Alloy 20 (CN7M) valves are specifically designed for service in highly corrosive environments. They provide excellent resistance to sulfuric acid and chlorides, making them ideal for critical applications in chemical processing and petrochemical industries. The anti-rust coating and smooth surface further enhance the valve's long-term durability.


Versatile Applications and Reliable Operation

Available in a broad size range (2 inch to 24 inch), this globe valve serves a variety of industries-including oil & gas, refineries, and power generation. It supports manual operation via handwheel, accommodates multiple end connections (RF and RTJ), and meets stringent face-to-face and testing standards for reliable sealing and performance.


Strict Adherence to Industry Standards

Manufactured to comply with ASME B16.34, ASME B16.10, and API 598, the valve assures consistent quality, safety, and interchangeability. Fire safe designs can be supplied on request, offering additional security for critical plant operations. High-quality sealing-PTFE, Grafoil, or metal-to-metal-ensures leak-tight performance under varied conditions.
