Globe Valve 3/8 Inch Class 1500 Socket Weld IBR
Stainless Steel ASTM A182 F304 | API 602 Certified | IBR Approved
Product Overview
The Supreme Valves 3/8 inch Class 1500 Globe Valve is API 602 certified and IBR (Indian Boiler Regulations) approved for use in steam boiler piping systems across India. The compact design per API 600/602 makes it ideal for high-pressure steam headers, boiler outlets, and process piping requiring small-bore Class 1500 valves.
The Stainless Steel ASTM A182 F304 construction provides excellent corrosion resistance and high-temperature strength for saturated and superheated steam service. The OS&Y (Outside Stem and Yoke) bolted bonnet design enables easy maintenance without disturbing the piping system.
Socket Weld ends per ASME B16.11 provide a permanent, high-integrity connection suitable for Class 1500 pressure ratings. The globe valve design provides reliable throttling capability for flow regulation in addition to on-off service.

Frequently Asked Questions
What is IBR certification and why is it required?
IBR (Indian Boiler Regulations) is a certification issued by the Chief Inspector of Factories and Boilers in India under the Indian Boiler Act, 1923. IBR requires that all pressure parts connected to a boiler in India must be certified. The globe valve with IBR certification means the valve has been tested and approved for use in steam boiler piping systems in India.
What is the difference between Socket Weld and Threaded ends?
Socket Weld (SW) ends per ASME B16.11 provide a higher pressure rating and stronger joint than NPT threaded ends, making them preferred for high-pressure boiler applications. The pipe slides into the socket and is fillet welded around the circumference, creating a leak-free joint that can withstand the high pressures found in Class 1500 steam service.
What does API 602 certification mean?
API 602 is the American Petroleum Institute standard for compact steel valves covering NPS 1/8 through NPS 2. This standard defines requirements for body wall thickness, stem materials, pressure-temperature ratings, and testing that exceed general-purpose valve specifications. For 3/8 inch Class 1500 globe valves used in high-pressure steam and boiler applications, API 602 certification ensures the valve meets rigorous petroleum industry standards.
Why use F304 stainless steel for this globe valve?
F304 (ASTM A182 Grade F304) stainless steel provides excellent corrosion resistance and high-temperature strength for steam service. The austenitic stainless steel composition ensures resistance to oxidation and scaling at elevated temperatures common in boiler applications. For Indian boiler and steam piping systems where water quality may vary and oxygen infiltration can cause corrosion, F304 provides reliable long-term performance.
