The ASCO 51900078 provides 5/2 directional control with one supply, two outlets and two exhausts, making it suitable for driving double-acting cylinders in both directions. Its pneumatic pilot operation can be used where electrical actuation at the valve is unwanted.
Typical applications include double-acting cylinders on automated machines, pneumatic control systems and like-for-like replacement of an ASCO Series 519 valve. When selecting a directional control valve, confirm the function, actuation and return type, port size and control requirements. For replacement applications, providing the existing valve part number helps confirm the correct variant.
