APPLICATION
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.

SPECIAL FEATURES
• Construction tested to EN 14597
• Immersion pocket with double heat sensors
• Test facility
• Capillary tube protected against kinking by steel sheath
• Immersion pocket with external thread
• Pressure balanced construction
