Spartan Extra Compact Thermoelectric Actuator

Spartan ME1708 Compact Thermoelectric Spring Return Actuator. Spartan’s thermoelectric actuators (ME1708 normally closed) utilize a highly refined wax filled element with piston/stem and patented packless elastomer seal. They are silent, extremely compact, inherently fail safe and can operate on hot and cold water, and low pressure steam to 15PSI. A PTC (positive-temperaturecoefficient) semi-conductive disc is both temperature control and heat source, inherently controlling at 90°C (194°F). The wax is chemically refined to melt at 70°C (158°F). The element expands in direct proportion to the amount of wax melted, driving the stem through its travel to open the valve. No other…
