ASCO™ Numatics Series 501 Directional Control Valves
The Numatics Series 501 is a line of general purpose automation valves designed for directional control and piloting applications requiring compact size, high flow capability, and energy savings.
Engineers can achieve the flow of a 15 mm to 20 mm valves in a more compact package, saving space, cost, and energy in their machine designs. In addition, no other valve in its class offers such a broad range of pressure regulator, pressure shut-off, and exhaust flow control accessories. The 501 Series valve’s 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.
