Product Overview
The CKD AMD21-X0574 is a precision-engineered air operated chemical liquid valve designed for reliable, leak-free control of aggressive and high-purity chemical fluids in industrial process systems. Manufactured by CKD Corporation, a globally recognized leader in fluid control technology, this pneumatically actuated valve utilizes a double-acting or spring-return air piston mechanism to drive a chemically resistant diaphragm or PTFE-lined sealing element. Unlike hydraulic pumps, this component functions strictly as a flow control device, providing accurate on/off isolation and directional control of chemical liquids without introducing contamination or pressure pulsation. Its robust construction and isolation design make it an ideal choice for automated chemical dosing, mixing, and distribution circuits where media compatibility and long service life are critical.

Engineering Features & Advantages
- Precision Performance: Fast-acting pneumatic actuator ensures rapid, repeatable open/close cycles with minimal response time, enabling accurate dosing and sequencing in automated chemical processes.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with chemically inert wetted materials that resist corrosion, swelling, and permeation from aggressive liquids.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, allowing drop-in replacement without modification to existing manifolds or piping.
- Leak-Free Isolation: Advanced diaphragm or bellows sealing technology prevents fugitive emissions and cross-contamination, ensuring operator safety and process purity.
- Compact & Modular Design: Space-saving footprint with optional position feedback, manual override, and NAMUR interface for seamless integration into PLC-controlled systems.
Typical Industrial Applications
This air operated chemical liquid valve is widely deployed in semiconductor wet processing equipment, chemical dosing and blending skids, pharmaceutical and biotech fluid handling systems, water treatment and wastewater neutralization plants, and automated laboratory analyzers. It is also suitable for use in printed circuit board (PCB) plating lines, surface treatment machinery, and any industrial process requiring precise, contamination-free control of acids, bases, solvents, or high-purity chemical reagents.
