Description
Covering 15 mm to 80 mm, this is Leader’s relief Valve (Non-IBR, Straight Type, Open Discharge). Opens in proportion to overpressure rather than lifting fully, which suits liquid service and thermal relief duties. The set pressure is specified at the time of order. Certified to IBR, with the Form III-C documentation that a boiler inspector will expect to see. A forged brass body to IS 319 — dense, compact and economical in the smaller sizes. Parallel BSP threads — the usual small-bore connection, and quick to replace in service. Every size in the range is listed above with its catalogue number and price.
