The TS131 temperature relief valve for heating systems according to EN 12828 is a self-acting valve which is activated by the flow temperature of the heat generator. It opens and discharges water from the heat generator or condensing coil at a flow temperature of 95 °C and thereby prevents a significant temperature rise in the heat generator.

Materials: Valve body, spring cover and brass temperature sensor well; double copper temperature sensor with capillary tube; copper capillary; valve piston made of brass; valve seat gasket of heat-resistant elastomer.

Features

• Separate double temperature sensor with capillary
• Capillary tube protected against kinking by steel sheath
• Immersion pocket with double heat sensors
• Pressure balanced construction
• Easy operation
