Frequently Asked Questions

What is an IBR approved globe valve?

An IBR approved globe valve is a valve that has been approved by the Indian Boiler Regulations (IBR) for use in boiler feed water applications. Globe valves use a spherical disc as the closing element and provide better throttling capability compared to gate valves. Supreme Valves India supplies IBR approved globe valves to IS 778 standards.

What are the applications of IBR Globe Valve?

IBR Globe Valves are used in boiler feed water lines, steam distribution systems, and pressure vessels. They are ideal for throttling applications where precise flow control is required. The renewable seat feature allows for easy maintenance without replacing the entire valve body.

What is the difference between inside screw and outside screw globe valves?

Inside screw globe valves have the stem thread inside the valve body, resulting in a non-rising stem design. Outside screw valves have the stem thread outside the body with a rising stem. Inside screw designs are more compact and prevent leakage along the stem at high pressures.

Where can I buy IBR Globe Valves in India?
