Safety thermostats are on/off actuators, which together with a valve, is used for the protection of secondary pipe installations in heat exchanger systems, which on the primary side are connected to steam, district heating, high pressure hot water or hot oil supplies.
The safety thermostat can be used either separately or combined with a regulating thermostat, whereby the regulating valve will also serve as a safety valve. By activating the thermostat the valve will close, whereby unintended increases in temperature and pressure in the secondary installations are avoided. The appropriate possible combination of regulating valve and thermostat simplifies the total pipe installation and makes it cheaper. |
