MiniBOOSTER Hydraulic Intensifier HC65-1.9-B-1

Product Description

The HC65 – 1.9 – B – 1 is a lightweight unit at 11.0 kg/ 24.2 lbs, designed for applications requiring high-pressure maintenance. It features a counterbalance valve, facilitating rapid cylinder movement by directing full inlet flow through the booster until the set pressure is achieved. Upon reaching high-pressure side H, automatic stall occurs, with continuous compensation for oil consumption to maintain pressure. Outlet pressure adjustment is achieved by varying the supplied pressure, with an optional orifice available to prevent overspeeding.

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.
