Abstract
A regulating valve having anti-seize characteristics provides a linear drive system intermediate a drive shaft connected to a motor and a lifter connected to the regulator spring. The linear drive system translates the rotational motion of the drive shaft into preferably, linear only motion of the lifter, thereby preventing binding internal to the valve.
