The HC5 is a double-acting miniBOOSTER incorporating two separate intensification circuits. As the function diagram indicates, changing the position of the control valve CV switches intensification from one circuit to another.
It is ideal for use in applications where high pressure is required in separate activation steps such as double-acting cylinders, combination cutter spreader tools, etc. Like the HC2, the HC5 is a compact unit weighing only 3.0 kg.
The basic operation is illustrated in the function diagram. Oil is fed through the directional valve CV to the IN port, flowing freely through the check valves KV1, KV2 and DV to the high-pressure side H. In this condition maximum flow through the booster is achieved giving a fast-forward function.
When pump pressure is reached on the high-pressure side H, valves KV1, KV2 and DV will close. The end pressure will be achieved by the oscillating pump unit OP. The unit will automatically stall when end pressure on 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.
