[. . . ] SM180 Diaphragm safety valve for solar systems Product specification sheet Application The membrane safety valves of this type are used as last safeguard for solar systems when the stipulated control and safety devices fail. They must therefore be capable to discharge the entire boiler output as steam in case of emergency. [. . . ] Construction The safety valve comprises: · · · · EN0H-1368GE23 R0609 · Änderungen vorbehalten Medium Water or glycol-water mixture, according to VDI 2035 Liquids of the fluid group 1 and 2 (pressure device guideline, item 9) which do not affect the materials used. Technical Data Installation position Opening pressure Horizontal with safety cap pointing up Factory preset to 2. 5, 3. 0, 4. 0, 6. 0, 8. 0 or 10. 0 bar Subsequent alteration of the setting is not permitted and is impossible without destroying the security cap Operating temperature -20 °C. . . +160 °C Connection size Internal thread on inlet 1/2", 3/4", Internal thread on outlet 1/2", 3/4", 1" Angled housing Adjustment spring Diaphragm Security cap with part label Brass housing Spring steel adjustment spring High grade synthetic material security cap Hot water resistant elastomer diaphragm Materials · · · · Valve size is defined by the size of the inlet connection www. honeywell. de/haustechnik 1 SM180 Diaphragm safety valve Method of Operation Do Diaphragm safety valves of this type are directacting safety valves in which the disc is pushed up by the pressure from the system against a spring which is holding the valve closed. 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.
