Control Valves with Thermoelectric Actuators
These two-way, three-way and 4 ported zone control valves all use a simple time proven thermoelectric actuator operating on the principle of the expansion of refined wax when heated through its melting point. They are silent, extremely compact, inherently fail safe (open or closed) and operate on steam to 15PSI temperatures.
Operating principle of a wax element with elastomer insert
Wax elements, their manufacturing processes and their application to regulation have been proven for decades. Even the most sophisticated requirements can be met using this simple yet extremely costeffective, precise and,above all, reliable technology.
This actuator is built on the tried and tested, totally silent wax expansion principle in conjunction with a unique intelligent position-encoding system.
The valve stroke responds precisely and reliably to the control signal within the shortest possible time.
