Snap acting thermostats - Snaps open or closed an electrical circuit when it senses the calibrated temperature - Rostra Vernatherm

http://www.vernatherm.com/snap_acting.html

Snap Acting and Open Air Thermostats. Sense heat through convection rather than conduction. Utilize a bimetallic, temperature-sensitive disc that snaps open/close switch contacts disrupting/re-estabishing continunity. Technical Drawing (PDF) - Horizontial Tabs. Technical Drawing (PDF) - Verticle Tabs. Open Air Thermostats are classified as our A-5011 series units and they are as versitile as our B200 closed body conduction type thermostats. The only difference between the conduction type. If you are unsu...

Thermal Valves - Rostra Vernatherm

http://www.rostravernatherm.com/pressure_relief.html

Are used to control pressure in a system. Pressure is relieved by forcing open a valve set to a specific limit which when met or exceeded allows the pressurized fluid to flow from an auxiliary passage out of the system. Once valve's reseating pressure is met the valve will close. Blowdown is quantified as a percentage of set pressures and refers to the reduction in pressure needed before the valve reseats. A poppet pressure relief valve is manufactured to be placed within a machined housing. Thermal Valv...
