In labs across the country, hot samples are collected and cooled in a sample cooler before being deposited into analyzers to collect data. These sample analyzers are expensive and delicate pieces of machinery, so what would happen should the cooler fail to lower sample temperature to a safe range before entering the analyzer? Simply, nothing good.
Irreparably damaged parts, expensive repairs, and delayed projects can be easily avoided by adding a fail-safe in between the cooler and analyzer – a thermostatic emergency shut-off valve.
The High Sample Temperature HST valve is an in-line thermal shut-off valve that is installed to sense the sample temperature when it exits the cooler and automatically control flow based on fluid temperature.
The HST is normally open to allow samples to pass through it. The sample temperature is constantly monitored by the valve’s internal thermally-activated actuator.
Should the sample temperature exceed the valve’s set-point, the HST rapidly closes and remains closed until the sample has sufficiently cooled to prevent over-heated samples from entering analyzers.
Self-operating and designed with a ram-type plug for a leak-proof seal, the HST is offered in a wide range of temperature shut-off points from 100°F to 185°F (37.8°C to 85°C) to suit any application.
The HST valve is unaffected by inlet pressure variations and functions completely mechanically, requiring no source of electricity to operate. Our valves are 100% Made In America with stainless steels components for a guaranteed long service life with no maintenance requirements.
Install the HST valve to take the worry out of protecting your lab equipment.
