MiniBOOSTER Hydraulic Intensifier HC75-7.6-B-12

Category: Tag:

Product Description

The HC75 – 7.6 – B – 12 is a lightweight unit at 2.8 kg/ 6.1 lbs, designed for applications requiring high-pressure maintenance. Featuring a counterbalance valve, it facilitates rapid cylinder movement by directing full inlet flow through the booster until reaching the set pressure. Automatic stall occurs upon reaching the high-pressure side, with continuous compensation for oil consumption. Outlet pressure adjustment is achieved by varying the supplied pressure, with an optional orifice available to prevent overspeeding.

Additional information

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.
