The HC5 miniBOOSTER


Photo: HC5 miniBOOSTER

HC5 versions: 11 different intensification factors

PIN: 20 – 200 bar (inlet pressure)

PH: 800 bar maximum (outlet pressure)

PRETURN: As low as possible (Return pressure to tank)

Intensification ratios: PH = (PIN – PReturn) i (Intensification)

Mounting: Inline tube

Accessories: Pilot operated dumpvalves incorporated
High Pressure in two directions



Image-link: Back to top of page.  Description

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.

Image-link: Back to top of page.  Functions

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 high pressure side H is reached. If there is a pressure drop on the high pressure side due to consumption or leakage, the OP valve will automatically operate to maintain the end pressure.
