nnnn

These two-way, three-way and 4 ported zone control valves

nnnn

all use a simple time proven thermo-electric actuator

nnnn

operating on the principle of the expansion of refined wax

nnnn

when heated through its melting point They are silent,

nnnn

extremely compact, inherently fail safe (open or closed) and

nnnn

operate on steam to ISPSI temperatures.

nnnn

Principles of Operation

nnnn

Spartan's thermoelectric actuators utilize a highly refined

nnnn

wax filled element with piston/stem and patented packless

nnnn

elastomer seal. A PTC (positive-temperature-coefficient)

nnnn

semi-conductive disc is both temperature control and heat

nnnn

source, inherently controlling at 90°C ( 194°F).The wax is

nnnn

chemically refined to melt at 70°C (IS8°F).The element

nnnn

expands in direct proportion to the amount of wax melted,

nnnn

driving the stem through its travel to close (or open) the

nnnn

valve. No other travel or thermostatic switches are

nnnn

required. Life expectancy is therefore in multiple decades

nnnn

and unconditionally guaranteed by Spartan Peripheral

nnnn

Devices for 5 years. For 230Vac, 50/60Hz versions choose

nnnn

models ME-1625 and ME-1725.

nnnn

Spartan thermoelectric

nnnn

valves are silent and extra

nnnn

compact for installation in

nnnn

low profile cabinets.
