WATTS STS20.S 0232620 Thermal Safety Valve 1/2″ 97°C

Advanced thermal protection for solid fuel and pellet boiler systems.

The WATTS STS20.S Thermal Safety Valve 1/2″ 97°C protects solid fuel and pellet boilers by discharging sudden temperature rises in a controlled manner. In addition, its dual safety element design maintains system protection even in the event of a failure. Furthermore, this valve activates automatically when boiler water reaches the maximum temperature.

The valve operates precisely at a 97°C set point and handles a maximum working pressure of 10 Bar. Moreover, its discharge capacity of 6500 L/h at 8 Bar makes it ideal for medium-scale installations. Its heat-sensitive capillary tube mechanism dissipates residual thermal energy when combustion cannot be stopped immediately. In addition, the 1/2″ female-female valve connection and 1/2″ male probe connection ensure easy integration into standard boilers. With a 145 mm probe pocket and a 1300 mm capillary tube, it provides thorough temperature monitoring.
