Common Pneumatic Formulas. Air Valves help to regulate pressure in the cylinder and are sized for flow capacity (Cv). Cv is based on the specific cylinder stroke & travel time requirements, as well as piston size. Cv is a coefficient that measures the quantity of air a device can pass.
Flow-regulators. Actuators / cylinders. Tubes and fittings. In this chapter we will be looking at pneumatic cylinders. Cylinders are the most important means of actuation in pneumatics. The cylinder transfers the energy that is stored in the compressed air into movement. They can be classified by: Design. Cylinders with piston rods.
Pneumatic power transmission methods are often the best way to move parts and tooling in industrial machines. These pneumatic systems perform a myriad of tasks in automated equipment such as clamping, gripping, positioning, lifting, pressing, shifting, sorting and stacking.

In order to detect the position of the piston, sensors which are triggered by a magnetic field are assembled onto the pneumatic cylinder. The cylinder piston is equipped with a magnet so that the sensor can receive a signal. The sensor is assembled onto the cylinder in the position where the signal is required.
Pneumatics is the utilization of compressed air in science and industry in order to perform mechanical work and control. We can either talk about pneumatics or pneumatic systems. In this course we define pneumatics as the control and transfer of power by using compressed air.
Gear Displacement Calculation: The volumetric displacement of a gear pump or motor can be approximated by measurement of the internal parts and substituting the values in the following formula: V = 6.03 × W × (2 x D -L) × (L - D ÷ 2) Where. L. = displacement in in3/rev. = gear width in inches.
