Frequently Asked Questions

What is a rising stem globe valve?

A rising stem globe valve has a stem that moves up and down with the disc as the valve is opened or closed. This provides a visual indication of the valve position without needing additional indicators. The stem thread is outside the valve body, making it an outside screw design.

What are the applications of IBR Globe Valve flanged?

IBR Globe Valves with flanged ends are used in large diameter boiler feed water lines, steam distribution systems, and power plant applications. They offer excellent throttling capability and the rising stem provides clear position indication. Flanged connections allow easy installation and maintenance.

What materials are used in IBR Globe Valve flanged construction?

IBR Globe Valves flanged use Cast Iron (IS 210 FG200) for body and bonnet, SS 410 for stem, and FG200 with SS 304 overlay for disc. The flanges conform to IS 1538 dimensions. These materials provide excellent strength and corrosion resistance for boiler applications.

Where can I buy large diameter IBR Globe Valves?

Supreme Valves India supplies large diameter IBR approved globe valves from Ahmedabad, Gujarat. Available sizes 1.5 to 12 inches (40mm to 300mm) with flanged connections. Complete IBR documentation provided. Export to UAE, Saudi Arabia, Qatar, Oman, Kuwait. Contact: +91 97732 78770.

What is the advantage of SS 304 overlay on disc?

SS 304 overlay on the disc provides excellent sealing surface that resists wear and corrosion. This extends the valve life and ensures reliable sealing even after many cycles of operation. The overlay can be re-machined if needed during maintenance.
