Sentry Thermal Shut-off Valve
The Sentry Thermal Shut-off Valve (TSV) is a fully mechanical valve designed to protect instrumentation and personnel from the damaging effects of excessive sample temperatures. The TSV unit is self-contained and automatically interrupts sample flow when the sample temperature reaches a preset limit. Prior to the introduction of the Sentry TSV, the most common means of high temperature protection was a senior (RTD or thermocouple) and a solenoid valve.
