TSV Thermal Shutoff Valve for High Temperatures

This valve ensures that you can shut down sample flow quickly when loss of coolant or sample flow surges occur. Withstanding temperatures up to 250°F (121°C), our Hi-Temp valve completely closes when sample temperature reaches up to 203°F (90°C) – all without operator intervention. The sensoe/actuator is directly exposed to the sample medium. High temperatures actuate the device in less than five seconds. Some of the causes og high temperatures include loss of cooling water, insufficient cooling water pressure or flow, high cooling water temperature, high sample flowo rate, a ruptured coil in the sample cooler, or a fouled or plugged sample cooler.

After each trip, an operator must manually reset it to ensure additional process safety and time for error correction. Each time the temperature shutoff valve is closed it will have a red visual indication of the postion and can even be added to an optional remote alarm via a switch.
