    摘要: The invention prevents overshoot from occurring in flow rate on the output side of a flow rate regulator when output flow rate is changed or the gas type distributed is changed. Thus, an automatic pressure regulator is provided to supply gas pressure to a flow rate regulator that includes a piezoelectric element driving type pressure regulating valve, a control pressure detector provided on the output side of the pressure regulating valve, and a controller to which a detected value P2 of the control pressure detector and a set value Pst for control pressure are input, wherein the controller supplies a control signal to a piezoelectric element driving unit of the pressure regulating valve using a proportional control system to perform valve opening regulation in which the proportional control system of the controller is set to control to bring about a residual deviation in control pressure by disabling an integral action.

    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.
