Sealed Heating System Pressure Relief Valve
Made from hot pressed brass, the Sealed Heating System Pressure Relief Valve (PRV), is predominantly used to protect closed-circuit water heating systems from overpressure. It has a separate seal seating from the diaphragm, giving improved scaling resistance, and a high grade glass fibre reinforced plastic twist cap.
Supplied with 1/2″ female connections and integral pressure gauge for system monitoring, it is set at 3.0 bar opening pressure which is indicated on the twist cap cover. The cartridge design also gives ease of service and replacement without the need to re-set the opening pressure.
