A family of linear voice coil actuators from BEI Kimco Magnetics (Vista, CA) include two 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.

Each actuator incorporates a magnetic extension or compression spring inside a coil assembly.
