513 Series Safety Relief Valves

Safety relief valves are typically used for pressure control on heat generators in heating systems, on hot water storage units in hydraulic and domestic water systems, and in hydraulic systems. On reaching the setting pressure, the valve opens and, by discharging into the atmosphere, prevents the pressure in the system from reaching dangerous levels for the generator and for the components installed in the system. 527 EST series valves are fail-safe devices, i.e. they are guaranteed to operate even in the case of wear or breakage of the diaphragm.
