Increased safety and longer life

Increased safety and longer life
BEI Kimco Magnetics has introduced a new family of linear voice coil actuators that provides increased safety and long service life. The new family features two patented spring designs based on magnetic, rather than mechanical technology. This technology ensures constant and precise valve position in either the open or closed setting when electrical power is off. OEMs designing products for safety-critical applications such as medical apparatus and other equipment that depend on maintaining a constant valve setting, will find the new actuators an ideal, low-cost solution.

The new magnetic designs make use of a mechanical spring unnecessary. Each actuator incorporates either a magnetic 'extension' or a magnetic 'compression' spring inside a coil assembly. In effect, the entire actuator can be described as a controllable electromagnetic spring.
