Pressure valve PRD can be used in liquid-filled transformer and regulator vessels. It helps to reduce overpressure due to an internal fault and therefore contributes to the integrity of the boiler. The pressure valve can be installed in any position or inclination on the cover or on the wall of the boiler. If necessary, several pressure valves can be fitted to one transformer. The pressure valve has a G 1 threaded housing according to UNI-ISO 228. The cover and housing are made of MS 58, Viton O-rings and all other parts are made of A2 stainless steel.
