Product Overview
The CKD AMD313R-10BUP-00N4F is a pneumatically actuated chemical liquid valve engineered by CKD Corporation for precise, contamination-free control of aggressive and high-purity process fluids. Operating on a normally closed (N.C.) air-operated piston/spring return principle, this valve uses instrument air pressure to actuate a flexible diaphragm or PTFE-sealed valve mechanism, isolating the working fluid from the actuator assembly. Its design prioritizes chemical resistance, bubble-tight shutoff, and clean operation, making it a critical component in semiconductor wet processes, chemical dosing lines, and high-purity fluid handling systems where media compatibility and leak integrity are paramount.

Engineering Features & Advantages
- Precision Performance: Pneumatic piston actuation delivers fast, repeatable open/close response with consistent sealing force, ensuring accurate chemical dosing and minimal dead volume in high-purity fluid circuits.
- Chemical Compatibility: Fluoropolymer wetted path and diaphragm isolation resist aggressive acids, bases, solvents, and high-purity chemicals, preventing media contamination and extending service life.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a robust spring-return fail-safe design that defaults to closed on loss of pilot air.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original CKD OEM standards, allowing drop-in replacement without modification to existing manifolds or piping.
Typical Industrial Applications
This air operated chemical liquid valve is widely deployed in semiconductor and electronics wet-bench processes, chemical dosing and blending systems, pharmaceutical and biotech fluid transfer lines, and high-purity industrial cleaning equipment. Its combination of pneumatic actuation, chemical-resistant construction, and leak-tight shutoff makes it suitable for any process requiring precise, automated control of aggressive or contamination-sensitive liquids.
