About this item

The Polyhydron Lever Operated Directional Control Valve (CETOP 03)-DL 06 is a lever-operated directional control valve designed for mounting on ISO 4401-03-02 standards. It features a completely encapsulated mechanism that protects against dirt and contamination, ensuring reliable performance.

The valve incorporates a five-chamber body and spool design, which reduces dynamic forces, minimizes pressure drop, and enhances overall performance and service life. Its balanced spool design ensures smooth shifting, high reliability, and long operational life.

Available in spring-centered, spring offset, and detented configurations, the DL 06 offers flexibility for various applications. The operating head can be rotated in 90° increments up to four positions, allowing convenient installation. Interchangeable spools and bodies simplify maintenance and reduce downtime.
