Description
Covering 15 mm to 80 mm, this is Leader’s relief Valve (Non-IBR, Right Angle, Enclosed 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. IBR approved and supplied with the Form III-C certificate required for steam service under the Indian Boiler Regulations. Bronze construction suits continuous water duty and takes repeated cycling without the seats degrading quickly. Taper BSPT threads seal on the thread itself, which suits duties where a parallel thread and washer would be awkward. Every size in the range is listed above with its catalogue number and price.
