Product Overview
The TOKYO KEIKI TGMDC-3-Y-PK-51 is a modular direct check valve engineered for seamless integration into ISO 4401 / CETOP sandwich valve assemblies. Manufactured by TOKYO KEIKI (Tokyo Keiki Inc.), a recognized leader in precision fluid power components, this modular check valve functions as a directional flow control element that permits free flow in one direction while positively blocking reverse flow. Its sandwich-style body mounts directly between a directional control valve and a subplate or manifold, eliminating the need for inline piping and reducing potential leak points. The “Y” designation indicates the specific port configuration and flow path arrangement, while the “PK” suffix denotes the sealing and interface variant. This valve is designed for reliable, maintenance-friendly operation in demanding industrial hydraulic circuits where compact stacking and precise flow control are essential.
