Walvoil Sd4/1 Directional Control Valve

What is a Directional Control Valve?

It’s essential to first know the role of a directional control valve before we get into the SD4/1. Directional control valves are integral components in hydraulic circuits and are utilized for directing the direction of fluid flow in the circuit. By manipulating the route the hydraulic fluid flows, directional valves are central to controlling actuator movement, pressure, and the responsiveness of the system.

Introduction to the Walvoil SD4/1 Valve

Walvoil SD4/1 is a monoblock directional control valve, where all the sections are formed in one block. It gives the unit a leak-proof, more compact, and easier-to-fit design. Specifically designed for the middle range of flow rates and pressures, the SD4/1 can be found on agricultural machinery, construction machines, and lifting systems.
