[. . . ] SM150 Diaphragm safety valve for closed heating systems Product specification sheet Application Membrane safety valves of this type are used to protect closed hot drinking water systems according to DIN 1988 and DIN 4753-1. [. . . ] If the opening force exceeds the force exerted by the spring, then the valve disc is lifted off the valve seat and the valve discharges the medium. In accordance with the requirements of the standard, the full discharge capacity of the valve will be achieved when the system pressure climbs to no more than 10% above the set pressure of the valve. Full shutoff must be achieved if the system pressure falls to below 80% of the nominal set pressure of the valve. For valves rated up to 3. 0 bar, the closing pressure can be taken as 0. 6 bar minimum.
