Description
This bronze Spring Loaded Safety Relief Valve, Open Discharge (Screwed) from Zoloto 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. Gunmetal to IS 318 Grade LTB-2 holds up in continuous water service without the dezincification that shortens brass fittings. 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. Size-by-size catalogue numbers and pricing appear in the table above.
