D03 Manual (Lever) Valve – D03M-4C

The D03 Manual (Lever) Valve, part number D03M-4C, is a D03‑series lever‑operated directional control valve (manual/lever actuation) built to the NFPA D03 interface; the D03M-4C is typically offered as a 3‑position spool (detent) with a tandem center and nominal D03 size, rated to 3000 psi with nominal flows around 7 GPM @ 3000 psi (10 GPM @ 1000 psi) and a broad operating temperature range—specifications and spool options are documented by the manufacturer and distributors.

Designed for rugged mobile and industrial hydraulic systems, the D03M-4C delivers simple, reliable manual control of cylinders and motors where electrical or pilot operation is not required; its NFPA D03 mounting, durable spool construction and industry‑standard porting make it easy to install and service, and it’s commonly used on construction equipment, agricultural implements, material‑handling machinery, trailers and other implement controls where dependable, low‑complexity directional control is needed.
