temperature sensing valves
The temperature sensing valves manufactured by Therm Omega Tech are stocked by Marspec Technical Products.
Therm-O-Tech valves are designed to sense temperature of ambient air and fluids and then operate a valve open or closed in response to the change in temperature. The heart of the valve is the wax thermoelement actuator that operates the valve.
A specially formulated paraffin and various adders to alter its operating characteristics are contained in a metal capsule. One side of the capsule is a flexible diaphragm that moves in response to the temperature-induced expansion and contraction of the paraffin mixture. As temperature changes, the wax thermoelement expands and moves a valve stem to either open or close a valve. This ingenious, self-powered system is used to operate a number of valve products:
- Freeze drain valves – Opens to drain water from eyewashes and safety showers to prevent freezing and pipe damage.
- Scald prevention valves – Opens to drain solar warmed water from outdoor water lines to prevent scalding.
- Ambient air temperature valves – Senses air temperature to turn steam tracing on and off. Saves energy and prevents product overheating.
- Fluid temperature sensing valves – Senses fluid temperature to operate steam tracing.
- Mixing valves – Precisely mixes hot and cold water or steam and cold water to provide a safe source of hot washdown water.
- Diverting valves – Senses fluid temperature and diverts the flow to an alternate flowpath.
