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.
