Watts STS 20 temperature safety relief valve, 2.0 m capillary tube The Safety Valve Watts STS 20 is a Thermostatic Protection that prevents any overheating of the water jacket in the fireplace insert. The valve is used in all types of chimneys or boilers, solid fuel such as coal, stone burns charcoal, wood or Koks heated, and protects against overheating of the water in the Zirconia in the case of interruption of power supplies. Advantages: – Look On Only A valve system, which is also in event of a two independent sensor system is the function of the STS 20 still. – The Dichtko lBen is controlled in the middle. A tilting motion making it completely eliminated. – No housing made of plastic, so not sensitive against external damage. – for Kurzzeitigem temperature increases to 125 °C it will cause no damage to the sensor. – If required, the Dichtko lBen be replaced very little effort. Area of application: the STS 20 temperature safety relief valve is required for use with fire pendant and heating systems with solid fuel. These systems can be designed for maximum 93 kW (yield 80000 kcal/h). The outlet Fuse Type STS 20 is a Druckunabhängiges valve that is the Flow Temperature of the heat Erzeugers upon reaching from 97 °C a water outlet on the household water warmer opens and therefore an increase in temperature above a maximum of 110 °C. Can be installed: The STS 20 temperature safety relief valve is connected to the hot water outlet of the hot water press. (image 1) it is the direction of the arrow to assemble. The immersion pipe with the sensors will be packed securely by our professional team in the AM Boilers screwed the socks. If Kettle with an approved safety heat exchanger the STS 20 in the cold water supply can be adornment.
