Introduction General Description Features and Benefits These valves are generally used to Suitable for the most demanding control the direction of flow in a industrial applications with flow hydraulic circuit. This, in turn, would capacities up to 380 l/min (100. control the direction of movement of a USgpm) and rated pressure of hydraulic cylinder, or the rotation of a 210 bar (3000 psi). fluid motor. High pressure and flow capability for DG17S-8 Lever Operated maximum cost-effectiveness.

3 DG17S4-10 Lever Operated Low shock characteristics to maximize machine life. Solid cast body and core passages for maximum strength and minimal pressure drop. Designed and backed by Vickers , with over 70 years as the global leader in fluid power and motion control . 3.
