Are there PID diagrams for double-acting and single-acting pneumatic valves that provide air supply and interlocking, as well as for the conversion of electrical signals to pneumatic signals?

For the air supply and interlock functions of double-acting and single-acting pneumatic valves, as well as the PID diagram for converting electrical signals into pneumatic signals, refer to the control process diagram below: 1. PID diagram for double-acting pneumatic valves: Input signals: Setpoint temperature, actual temperature feedback signal; Output signal: Input signal for the pneumatic actuator. 2. PID diagram for single-acting pneumatic valves: Input signals: Setpoint temperature, actual temperature feedback signal; Output signal: Input signal for the pneumatic actuator. Notes: 1. When connecting the pneumatic actuator, it is necessary to select the appropriate interface type (single-acting or double-acting) based on the valve type； 2. For continuous control, a PID control algorithm is required to achieve temperature control ； 3. During the control process, conversion between gas signals and electrical signals is required, and a conversion module can be used to accomplish this ； 4. Interlocking functionality can be achieved by configuring appropriate signal inputs/outputs and sensors. I hope the above information is helpful to you. .
