Speed valves

Hi-Tech Marketing Services offers Speed valves manufactured by Mini-Booster Hydraulic A/S, Denmark. Product features: high flow and full force; compact design, higher-pressure rating, faster operation, and power saving techniques. These products are ideal for presses, injection moulding machines, excavators, loaders, cranes, waste compactors, etc. The speed valve series is a range of re-generative valves increasing the speed of the forward movement of a double acting cylinder. This is achieved by diverting the oil from the B-side of the cylinder to the A-side. The total flow used to move the cylinder forward is then QA = Qpump + QB. The speed-valves will not affect the return speed of the cylinder. As an option an unique built in control valve automatically changes from speed to force when the cylinder meets resistance in the forward direction. The speed-valves are designed as in-line valves, easily installed into any hydraulic circuit. No additional controls are needed, as the control valve controls the speed-valves in the system.
