Solenoid Valve Schematic Explained. The s36c closed centers solenoid valve is a specially designed solenoid valve made for spring return actuators in three position applications. During the mid position the air is trapped inside the solenoid valve keeping the springs from decompressing and keeping the actuator open or in a semi open position.
A 2 way normally closed solenoid valve has 2 pipe connections an inlet called the cavity port and an outlet called the body orifice port. This is the body of the valve to which the solenoid valve is connected. Solenoid valve is a control units which when electrically energized or de energized either shut off or allow fluid flow.
All solenoid valves no matter the design are specified to be one of two general types.
During the mid position the air is trapped inside the solenoid valve keeping the springs from decompressing and keeping the actuator open or in a semi open position. Pressure of air supply symbol. This symbol indicates that a port is closed and is neither passing or exhausting gas. The orifice closes and flow through the valve stops.
