DEMONSTRATION WORKING MODEL OF PNEUMATIC CIRCUIT OF SPEED CONTROL OF DOUBLE ACTING CYLINDER
Pneumatic Circuit for Speed Control of Double Acting Cylinders.
Pneumatic cylinders can be directly controlled by actuation of final directional control valve as shown in fig.
These valves can be controlled manually or electrically.
This circuit can be used for small cylinders as well as cylinders which operates at low speeds where the flow rate requirements are less.
When the directional control valve is actuated by push button, the valve switches over to the open position, communicating working source to the cylinder volume.
This results in the forward motion of the piston.
When the push button is released, the reset spring of the valve restores the valve to the initial position [closed].
The cylinder space is connected to exhaust port there by piston retracts either due to spring or supply pressure applied from the other port.
