Brass Safety Valve
A brass safety valve with nickel-plated brass body and spring-loaded threaded safety valve. The safety valve automatically opens when the protected system’s pressure exceeds the set value, releasing excess pressure, and closes again when pressure returns to normal; it protects boilers, water heaters, compressors and pressure vessels against damage and accidents from overpressure.
Corner type (Italian type), straight type and diaphragm models are offered between 1/2″ and 3″. Standard models feature EPDM seals, adjustable 0–12 bar, pressure class PN16 and are used up to 130 °C; models suitable for steam operate up to 200 °C. Diaphragm models with adjustment ranges such as 3-4-5 bar and 7-8-9 bar are common in heating and hot water installations.
