Van bảo vệ quá nhiệt Sentry 7-01137E  SENTRY TSV THERMAL SHUTOFF VALVE

The Sentry TSV is a self-contained, mechanical device that protects operators, analyzers and sampling components from high temperature liquids. It is an economical and reliable mechanical replacement for a solenoid shutoff valve and temperature controller, requiring no external source of electricity, air or hydraulics.
The sensor/actuator is directly exposed to the sample medium. High temperatures actuate the device in less than five seconds. Some of the causes of high temperatures include loss of cooling water, insufficient cooling water pressure or flow, high cooling water temperature, high sample flow rate, a ruptured coil in the sampler cooler, or a fouled or plugged sample cooler.

TSV
BENEFITS
A reliable mechanical solution that requires no electricity to operate, the Sentry TSV
provides positive closure. It must be manually reset after a trip, which ensures that sample flow is not resumed before the cause of the system upset has been corrected.
The Sentry TSV should be installed downstream of the pressure-reducing device and upstream of analyzers, flowmeters and other low-pressure devices. After a trip, the upstream side of the Sentry TSV will be exposed to the full source pressure. A red indicator readily provides visual indication of valve position, and an optional switch is available to provide a signal for a remote alarm.
