ABSTRACT:
An integrated process control valve includes a fluid valve body having an inlet for receiving fluid, an outlet for discharging fluid, a fluid flow passage connecting the inlet and outlet, and a controllable throttling element which is moveable to selectively vary the flow rate of fluid through the fluid flow passage. The valve also includes an actuator coupled to the valve body and responsive to control signals for selectively moving the throttling element, a first pressure sensor disposed at the inlet of the valve body for producing a first signal representing the pressure of the fluid at the inlet, a second pressure sensor disposed at the outlet of the valve body for producing a second signal representing the pressure of the fluid at the outlet, a position sensor for producing a position signal indicating the position of the throttling element, and a utilization device for receiving the signals and either producing a display representing the signal values and/or producing control signals for supply to the actuator to cause the actuator to move the throttling element to thereby vary the fluid pressure at the inlet and outlet of the valve body. The control signals include pneumatic signals for developing pressures in the actuator to cause the actuator to move the throttling element. Sensors are provided for detecting the values of the pneumatic signals which may be displayed by the utilization device along with the display of representations of the other signal values, including the position signal values.
