摘要： In a step motor driven cam valve a stem freely ascends and descends within a body having an in-flow passage, an out-flow passage, a valve chamber, and a valve seat. The stem is descended by an actuator, composed of a step motor and a cam mechanism located at a position above the stem, that changes a rotational motion of the step motor to a linear motion and transmits the linear motion to the stem. A diaphragm within a valve chamber or a valve body at a lower end part of the stem rests on the valve seat. A lift support mechanism that supports the actuator to freely ascend and descend is arranged at a bonnet that covers the valve chamber. A height fine-adjustment mechanism, arranged at the lift supporting mechanism, finely adjusts the height of the actuator relative to the stem so as to perform zero-point adjustment of the valve.
