A pneumatic circuit is an interconnected set of components that convert compressed gas (usually air) into mechanical work.
In the normal sense of the term, the circuit must include a compressor or compressor-fed tank.
In single-acting cylinders, the port extends using compressed air and retracts using an open coiled spring.
While passing through the restricted way of throttle, compressed air flow takes place.
This valve is used to delay the actuation of a cylinder after pressing the push button or pedal.
