Thermal discharge safety device model 544, DN15 (½”) IT, with backfeed

The valve can be installed horizontally, vertically or in inverted position. The thermowell of the temperature sensor supplied with the valve must be installed on the supply line at a distance < 0.5 m from the heat generator or at the highest point in the boiler and in any case before the outflow line. Use of the thermowell supplied with the valve is prescribed.

• Used with a double sensor fuse as a safety device in heating systems that use a stove or fireplace as a heat generator. The device combines thermal flow protection and a filling valve in one block, which can be activated simultaneously with positive safety when controlled by a remote sensor.
