Honeywell offers a reliable range of high performance safety products to ensure optimum safety in unvented hot water systems, water heaters and compressed air systems etc. From diaphragm safety valves through thermostatic mixing valves to complete safety groups. They require an extremely low level of maintenance and are service-friendly.
Safety Valves
High performance safety valves include diaphragm-type safety valves for pressurized water heaters through safety valve combinations for water heaters and direct loaded safety valves for compressed air vessels or silo tank vehicles.
Diaphragm Safety Valve for Closed Water Heaters - SM152
Type SM152 diaphragm-type safety valves are used to protect pressurized water heaters according to the requirements of DIN 4753, Part 1 and DIN 1988. In accordance with statutory requirements, the diaphragm safety valve is preset to the required fixed set pressure by the manufacturer and is sealed with an embossed security cap marked with the test badge and pressure rating to prevent unauthorized tampering with the setting. Subsequent alteration of the setting is not permitted and is impossible without destroying the security cap. The preset pressure is embossed on the security cap.

-Set pressure adjustment at factory
-Standard pressure settings between 0.9 and 4.3 bar in steps of 0.1 bar
Thermostatic Mixing Valves
Thermostatic Mixing Valves provide control of the water temperature and are used
- For centralized control on hot water supply units
- For localized control adjacent to point-use outlets
- For use with solar-heated hot water units
- In heating systems with underfloor heating
- For limiting boiler return temperatures
