Product Overview
The Parker DX3-621-70 (part number 12152275) is a pneumatic directional control valve from Parker’s DX series, engineered to manage the start, stop, and direction of compressed air flow within industrial automation and process circuits. This valve operates on a solenoid-actuated spool principle, in which an electrical signal shifts an internal spool to route supply air to the selected outlet port while simultaneously exhausting the opposite port. As a directional control component rather than a fluid power generator, it functions as a switching and sequencing element within pneumatic control systems, providing reliable actuation of cylinders, rotary actuators, and air-operated process equipment. Its compact body, standardized porting, and robust sealing arrangement make it a direct-fit replacement for OEM installations requiring dependable pneumatic circuit control.
