Product Overview
The PARKER PCL401-04-HK24-110 (part number 20078904) is a high-performance pneumatic directional control valve engineered by Parker Hannifin for precise actuation and reliable switching of compressed air circuits in industrial automation systems. Featuring a robust 4-way, 2-position (4/2) spool configuration, this valve directs airflow to double-acting cylinders and pneumatic actuators with rapid response and minimal pressure drop. The HK24 solenoid pilot operator with a 110V AC coil ensures consistent, low-power actuation, while the PCL401 series body is constructed for demanding continuous-duty operation. As a direct-acting, poppet-and-spool hybrid design, it delivers leak-tight sealing, high cycle life, and dependable performance in process and pneumatic control applications.
