D05 Manual (Lever) Valve – D05M-4B

The D05 Manual (Lever) Valve D05M-4B is an NFPA/ISO D05 (NG10) pattern manual lever directional control valve configured as a 3-position detent closed-center (configuration 4 = 3-position detented; function B = all ports blocked) with nominal flow ratings of 12 gpm at 3000 psi and 18 gpm at 1000 psi, a maximum operating pressure of 3000 psi, ISO 4401-05/NFPA subplate mounting, robust construction rated for long life (designed for ~30 million spool shifts), approximate weight 8.8 lb, and an operating temperature range of 40–160°F; recommended fluids are petroleum-based ISO VG32–68 with 25 micron or better filtration.

Built for industrial and mobile hydraulic circuits, the D05M-4B delivers stable manual positioning via detent, a zero-flow closed center for reliable load-holding and safe neutral, low internal leakage, and straightforward NFPA D05 interchangeability for easy integration into machine controls, lifting/transport equipment, and other applications requiring manual directional control up to 3000 psi; it is serviceable, compact, and optimized for high-pressure, moderate-flow hydraulic systems.
