ThermOmegaTech® High Temperature Thermal Shut Off Valve HST

Description
Operation The High Sample Temperature (HST) Safety Thermal Shutoff Valve is used to sense the sample temperature after the sample cooler and control flow based on fluid temperature. This valve is normally open and allows the sample to pass through it. If the sample temperature exceeds the valve set point, the thermal actuator inside the HST will close the valve to protect expensive and delicate analyzers and other instruments from over-temperature damage. Once the fluid cools back below the set point, the valve will automatically reset open again. Benefits Self-operating – No outside power required Protects expensive and delicate sample analyzers Automatically resets when sample cools Easy installation Superior value vs. more expensive electric valves Design Features Exclusive self-actuating Thermoloid® sensor/controller Ram-type plug provides tight shutoff Operating temperatures unaffected by variable inlet pressures Wide choice of temperature set points available Corrosion resistant – all stainless steel construction

Datasheet Summary
Powered by GS/AI

The HST series is an in-line, self-operating thermal shut-off valve designed to protect sample analyzers by automatically closing when sample temperature exceeds a set point and reopening upon cooling. It features an exclusive Thermoloid® thermal actuator and all 300-series stainless steel construction with an EPDM or Viton® seal and PTFE seat ring. Available in 1/2 NPT size, it has a maximum operating pressure of 3000 PSIG at 300°F and a body rating of 3000 PSIG at 600°F. Operating temperatures are unaffected by inlet pressure variations, and closing temperature is typically 10°F above the opening set-point, with options including 100°F to 185°F.
