MiniBOOSTER Hydraulic Intensifier HC25-6.6-A-1

Product Description

The HHC25 – 6.6 – A – 1 is a compact, 2.3 kg/5.0 lbs unit designed for applications requiring high pressure. It features a counterbalance valve for rapid cylinder movement and automatic stall at the high-pressure side. Continuous pressure maintenance is ensured through oil consumption compensation. Outlet pressure adjustment is achieved by varying the supplied pressure, with an optional orifice available for overspeed prevention at the R-port.

Function description

The basic operation is illustrated in the function diagram. Oil is fed through the directional valve (in the customer system) to the IN port, flowing freely through the internal check valves to the high-pressure side H. When pump pressure is reached on the high-pressure side H, the internal check valves will close. The end pressure will be achieved by the oscillating pump unit OP. The unit will automatically stall when the high-pressure side H is reached. If a pressure drop on the high-pressure side exists due to consumption or leakage, the OP valve will automatically operate to maintain the end pressure.
