Product Overview
The CKD ADK11-20A-R3H is a pilot operated 2-port solenoid valve engineered for precise on/off control of compatible process and pneumatic media within industrial fluid systems. Manufactured by CKD Corporation, a globally recognized authority in fluid control technology, this valve utilizes a pilot-operated diaphragm/piston architecture that allows a compact solenoid coil to control significantly higher flow rates and line pressures than direct-acting designs. The ADK11 series is a mainstay in factory automation, pneumatic actuation circuits, and general process control, offering reliable switching performance, low power consumption, and long service life. Its 2-port (2/2-way) normally closed configuration makes it ideal for shut-off, isolation, and supply control duties in demanding industrial environments.

Engineering Features & Advantages
- Precision Pilot-Operated Performance: The pilot-assisted design enables reliable sealing and high flow capacity with minimal solenoid power, ensuring consistent actuation and precise media control across varying pressure differentials.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust coil insulation, durable diaphragm/piston sealing, and resistance to vibration and thermal cycling.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original CKD OEM standards, ensuring drop-in interchangeability without modification to existing manifolds or piping.
- Low Power Consumption: Pilot operation reduces the electrical load on control systems, allowing multiple valves to be driven from standard PLC outputs without additional relay hardware.
- Fast Response & Long Service Life: Optimized pilot orifice and spring return mechanism deliver rapid opening/closing cycles with minimal wear, extending maintenance intervals in high-cycle applications.
Typical Industrial Applications
The CKD ADK11-20A-R3H is widely deployed across heavy industrial sectors including plastic injection molding machines for mold cooling and air blast control, metallurgical presses for hydraulic clamping and lubrication circuits, construction and marine hydraulics for
