The ASCO 520-00-190 provides 3/2 directional control with one supply, one outlet and one exhaust port. It is suitable for single-acting pneumatic cylinders, pilot signals and on/off air control applications. The valve uses pilot/pilot actuation and a 24 V AC coil for compatible control systems.
Typical applications include automated machines using single-acting cylinders and pilot circuits, control panels operating 24 V AC coils, and like-for-like replacement of an ASCO Series 520 valve. When selecting a directional control valve, confirm the function, actuation and return type, port size and coil voltage. For replacement applications, providing the existing valve part number helps confirm the correct variant.
