Frequently Asked Questions

What is an IBR approved gate valve?

An IBR approved gate valve is a valve that has been approved by the Indian Boiler Regulations (IBR) for use in boiler feed water applications. IBR approval ensures the valve meets safety and quality standards specified by the Indian government for pressure equipment. Supreme Valves India supplies IBR approved gate valves manufactured to IS 778 standards.

What are the applications of IBR Gate Valve?

IBR Gate Valves are primarily used in boiler feed water lines, steam distribution systems, and pressure vessels that require IBR approval. They are suitable for water, steam, and oil applications in power plants, refineries, and industrial boiler systems. The non-rising stem design allows for installation in confined spaces.

What materials are used in IBR Gate Valve construction?

IBR Gate Valves typically use Bronze (IS 318 LTB2) for body and wedge, Forged Brass (IS 6912) for bonnet and stem, and PTFE for gland packing. The specific materials may vary based on size and pressure rating. Supreme Valves India provides complete material traceability with mill test certificates.
