D03 Manual (Lever) Valve – D03M-4A

The D03 Manual (Lever) Valve, part D03M-4A, is a compact D03‑size directional control valve actuated by a manual lever and sold as a ready-to-install unit for mobile and industrial hydraulic systems (see product listing). It delivers robust performance with a nominal flow rating around 7 GPM and a maximum operating pressure up to 3000 PSI, and the D03 series is offered in multiple spool configurations and durable construction for heavy-duty use.

Built for dependable, hands‑on directional control, the D03M-4A enables precise actuation and load‑holding for cylinders and motors, making it ideal for implements, lift/tilt functions and auxiliary circuits on construction, agricultural and mobile equipment. Its compact footprint and high pressure/temperature ratings simplify installation in inline or manifold configurations where electric or pilot signals are impractical, while the proven D03 design offers long service life and field serviceability for demanding hydraulic applications.
