Valve Control Circuit

Directional air control valves are the building blocks of pneumatic control.

Valve control circuit.

Pneumatic circuit symbols representing these valves provide detailed information about the valve they represent. Symbols show the methods of actuation the number of positions the flow paths and the number of ports. Three speed meter in flow control circuit using modular valves mounted on bar manifold. Extending at middle speed.

Here is a brief breakdown of how to read a symbol. The code p0007 indicates a potential problem with the shutoff solenoid or its electrical circuit. The solenoid we have picked for this tutorial is our plastic water solenoid valve perfect for controlling flow to a drip irrigation system but this tutorial can be applied to most inductive loads including relays solenoids and basic dc motors. Diagnostic trouble code dtc p0007 stands for fuel shutoff valve a control circuit high it is triggered when the powertrain control module pcm perceives a problem with the fuel shutoff valve or its circuit.

The circuit requires an input voltage vcc to actuate the solenoid as well as a control signal input from a controller function generator or timing circuit which switches a transistor. In this tutorial we will be controlling a solenoid with an arduino and a transistor. Code p0010 is defined as camshaft position cmp actuator intake left front bank 1 circuit malfunction and is set when a fault is detected in the electrical circuit that controls the variable valve cam timing system.
