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.
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.
All pneumatic systems will have certain basic components. The first is a compressor, and then a system to distribute the clean, dry air it produces. Common pneumatic components on automated machines include: • air preparation system (shut-off/lock-out, combination filter/regulator, soft start valve) • control valves and manifolds

BASIC PNEUMATIC FORMULAS. Basic Valve Sizing: Air valves are sized for flow capacity (Cv) based upon a given cylinder piston size, stroke and travel time requirements. Cv us actually a flow coefficient that measures the amount of air a device can pass. The following formula can be used for air valve sizing:
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. Rodless cylinders. Diaphragm cylinders. Rotary cylinders. Movement. Linear . Rotary = turning. Function. Single-acting.
