Control Valve Circuit Diagram

Schematics are generally easier to read and understand than wiring diagrams.

Control valve circuit diagram. Directional air control valves are the building blocks of pneumatic control. Valves are the most complicated symbols in fluid power systems. Pneumatic circuit symbols representing these valves provide detailed information about the valve they represent. Wiring diagrams wiring diagrams show components mounted in their general location with connecting wires.

Here is a brief breakdown of how to read a symbol. The idle air control valve also known as the idle speed control valve regulates the idle speed of your engine. Schematic diagrams schematic diagrams show components in their electrical sequence without regard for physical location. Schematic diagrams are used to troubleshoot and install control circuits.

Fluid power system diagrams require much more complex valve symbology than standard p ids due to the complicated valving used in fluid power systems. This is a very simple animated illustration on the basics of hydraulic schematic symbols. Symbols show the methods of actuation the number of positions the flow paths and the number of ports. This is controlled by the engine s computer.

A wiring diagram is. Valves provide the control that is required to ensure that the motive media is routed to the correct point when needed. The solenoid draws a continuous current of 700ma when energised and a peak of nearly 1 2a so we have to consider these things while designing the driver circuit for this particular solenoid valve. Sometimes parts go bad which results in your car idling strangely or stalling.

The complete circuit diagram for solenoid driver circuit is shown in the image below.
