Description
This bronze Spring Relief Valve, Angle Type, Screwed from DRP covers 15 mm to 50 mm. 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. Bronze construction suits continuous water duty and takes repeated cycling without the seats degrading quickly. Screwed BSP ends keep installation simple at small bores and allow a valve to be changed with two wrenches. Used for thermal relief and liquid overpressure protection.
