Product Overview
The OMFB HDS ISO 34 D(R) directional control valve (part number 601-001-10343) is a high-performance, sectional-type hydraulic directional control valve engineered by OMFB, a recognized manufacturer of precision hydraulic components for mobile and industrial applications. This valve operates on a spool-and-bore principle, where a precision-machined sliding spool is displaced within a honed valve body to route, block, or divert pressurized hydraulic fluid between the pump, actuator, and tank ports. Configured to ISO 4401 / CETOP 03 (NG6) interface standards, the HDS series valve serves as a central control element in hydraulic circuits, enabling precise directional control of single- and double-acting cylinders, hydraulic motors, and rotary actuators. Its robust sectional construction and D(R) spool configuration make it a reliable choice for demanding industrial and mobile hydraulic systems requiring dependable flow direction and load-holding capability.
