The Numatics 501 Series directional control valve is designed for directional control and piloting applications requiring compact size, high flow capability, and energy savings. The general automation valve delivers up to two times greater flow than previous models. Engineers can achieve the flow of a 15 mm to 20 mm valve in a more compact package, saving space, cost, and energy in their machine designs. The pressure shut-off option permits users to replace individual valves without stopping their production process — reducing line downtime and maintenance. The combination of the pressure regulator and the Numasizing engineering tool can dramatically minimize air and energy consumption. The valve’s modular design also permits easy configuration and modification.
