Description

The HC25 is a compact unit weighing only 2.3 kg. It is ideal for use in a variety of applications where building and maintaining high pressure is required.

The HC25 incorporates a counterbalance valve, which allows fast forward movement of a cylinder by directing the full inlet flow to pass directly through the booster section until the set pressure has been reached. Hereafter the counterbalance valve opens, and the booster starts oscillating.

The HC25 booster will automatically stall when the high pressure side H is reached. The booster will continuously compensate for oil consumption to maintain the high pressure. Adjustment of the outlet pressure is carried out by varying the supplied pressure.

An optional orifice can be mounted in the booster to reduce inlet flow to the maximum allowed for the intensification ratio selected.

Functions

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 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.
