Abstract: A highly versatile drive arrangement that drives a linearly reciprocating piston of a water conditioning unit control valve without imparting any significant side loads on the support structure for the piston's drive rod or the associated seals. The drive arrangement includes a reversible electric motor and a motion converter, such as a lead screw arrangement, that converts the rotary motion of the electric motor's pinion or other output element to reciprocating linear motion of the piston.
