Technical information

Operating principle
Mechanical thermal shut-off, manual reset
Set points
43, 49, 55, 60, 67, 71, 95 °C

SENTRY TSV (Thermal Shut-Off Valve) is used to protect analyzer sensors on the sample line from high temperature. If the sample temperature on the panel exceeds the set value, this mechanically operated valve automatically cuts off sample flow. This protects the cooler, flow indicator, BPRV and sensors from damage, prevents steam discharging to atmosphere and ensures operator safety.

Typical causes of a temperature rise are loss of cooling water, high sample flow rate, high cooling water temperature, a dirty or clogged sample cooler and operator error. The valve requires a manual reset and has a visual trip indicator.

TSV features

  • Mechanical, unpowered automatic shut-off valve
  • Listed set points: 43, 49, 55, 60, 67, 71 and 95 °C (depending on model code)
  • Requires manual reset; visual trip indicator
  • Helps protect the secondary cooling system (TCU) from overload
  • W-270 HTSO high-temperature shut-off valve option

If you state the shut-off temperature you want, Tetra will supply a TSV with a suitable set point.
