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
