Directional valves such as Parker Hannifin's B3G-Series threeway (left) and four-way valves are often used to control pneumatic operations. Directional-control valves are vital in any pneumatic ...

Directional-control valves are common in pneumatic systems. They control compressed-air flow to cylinders, rotary actuators, grippers, and other mechanisms in packaging, handling, assembly, and ...

The paper investigates, by means of a 3D, steady-state, incompressible and isothermal CFD analysis, the influence of the notch shape and number on proportional directional control valves metering edge ...
