The Sentry® high-temperature shut-off valve is designed for use with sampling systems to shut off flow when the sample temperature becomes too hot.

The valve is suitable for grab sample or instrument applications that could experience a loss of coolant or surges in sample flow rates, which would cause the sample temperture to rise suddenly.

BENEFITS

The valve can be installed directly downstream of the primary cooler to protect more

vulnerable components further down the line. This is advantageous for the protection of personnel and instruments that could otherwise be harmed by high temperature samples.

The valve responds only to temperature. Under normal operation the valve is fully open. If the sample temperature reaches 115°F (46°C), the thermal element within the valve begins to close the inlet orifice. The inlet orifice is fully closed when the sample reaches 125°F (52°C). The valve automatically opens as the element cools
