D03 Manual (Lever) Valve – D03M-2B

The D03 Manual (Lever) Valve — part D03M-2B — is a compact NFPA D03‑pattern, 4‑way directional control valve with manual lever actuation and a 3‑position spring‑center closed spool. It is rated to 3000 psi maximum and is commonly specified for approximately 7 GPM service (with higher flow capability noted at lower pressures), with an operational temperature range typically around 40–160°F, making it suitable for standard mobile and industrial hydraulic systems.

Because of its compact D03 footprint and robust high‑pressure capability, the D03M-2B provides reliable, low‑cost manual control for cylinders, motors and auxiliary circuits where simple operator control, low pressure drop and predictable neutral behavior are required; the spring‑center closed spool prevents unintended load motion in neutral for safer operation. Typical applications include mobile equipment controls, small industrial machines, material‑handling units and service/auxiliary hydraulic circuits where compactness and ease of manual operation are priorities.
