Gate, Globe & Check Valves

Manual & automated - full IBR boiler-mounting range from Leader Valves.

Gate and globe valves are the standard multi-turn valve types for pipeline isolation and throttling; check (non-return) valves prevent reverse flow. Boiler mountings extend this range with valves specifically approved under IBR (Indian Boiler Regulations) for steam and pressure-vessel duty.

We supply forged and cast steel gate and globe valves, dual-plate and swing check valves, and the full Leader Valves boiler-mountings line - safety valves, blow-off valves, steam traps and feed check valves - for power and process steam systems.

Frequently asked

What is IBR approval and why does it matter for boiler valves?

IBR (Indian Boiler Regulations) governs the design, manufacture and certification of boiler and pressure-vessel fittings in India. Leader Valves boiler mountings are manufactured to meet IBR requirements - a genuine compliance requirement for boiler installations, not an optional spec.
