Product Overview

The CKD AMD513R-25BUP-00N4H 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, air-operated piston actuation principle, this valve uses an external pilot air signal to drive the valve element against a return spring, delivering positive shut-off and repeatable open/close cycling without exposing the solenoid or actuator to the media. The AMD series is purpose-built for fluid handling circuits where chemical compatibility, leak-tight sealing, and fast response are critical, making it a dependable control component in semiconductor wet processes, chemical dosing skids, and industrial fluid transfer systems.

Engineering Features & Advantages

  • Precision Performance: Air-operated piston actuation delivers fast, repeatable open/close response with positive shut-off, ensuring accurate metering and isolation of chemical liquids in critical process lines.
  • Chemical Compatibility: Wetted-path construction and chemical-grade sealing materials resist attack from aggressive process fluids, extending service life in corrosive media handling.
  • Industrial Reliability: Built for continuous operation under severe industrial conditions, with a robust actuator isolated from the media to protect the pilot circuit.
  • Direct Fit Replacement: Exact dimensional and functional compatibility with original CKD OEM standards for drop-in service and minimal downtime.

Typical Industrial Applications

Ideally suited for semiconductor and electronics wet-process
