Other Valves | LK 519 ThermoSafe 131 LK 519 ThermoSafe LK 519 ThermoSafe is a thermal safety relief valve for solid fuel boilers with built-in water heaters or cooling coils. The safety relief valve prevents the temperature of the boiler water from rising above the boiling point. When temperature levels are too high the valve opens to let cold water flow through water heater or cooling coil, thus reducing the temperature of the boiler. LK 519 ThermoSafe has two, separately functioning, temperature sensors for added safety. LK 519 ThermoSafe safety relief valve is installed on the outlet pipe of water heaters. The inlet pipe is recommended for cooling coils as such an installation would protect the armature from impurities caused by lime scale and other deposits. The arrow on the valve housing indicates the direction of the flow. The sensor pocket is screwed into the designated connection on the boiler. It is easier to install if the sensors are first removed from the pocket. The installation should be checked regularly. It is necessary to clean the valve seat in order to remove foreign particles and deposits. To activate the manual discharge and thereby cleaning the seal seat, press a few times on the red button on top of the valve.
