Hydraulic manifold-mounted directional control valves, as designated by CETOP standards like D03 (NG6), D05 (NG10), D08 (NG25), etc., are valves specifically designed to be mounted onto a manifold or subplate. These valves are commonly used in hydraulic systems to control the flow of fluid and direction of movement in machinery and equipment. The manifold mounting allows for the consolidation of multiple valves onto a single manifold block, simplifying installation, reducing space requirements, and minimizing potential leak points. This configuration enhances system efficiency, reliability, and ease of maintenance, making it a preferred choice in various industrial applications.
