MiniBOOSTER Hydraulic Intensifier HC225-2.5-B-1

Product Description

The HC225 – 2.5 – B – 1, weighing up to 3.3 kg/ 7.2 lbs, is a compact unit ideal for high-pressure applications. It incorporates a counterbalance valve for swift cylinder movement and a pressure reducing valve (PRV) to maintain stability despite tank line pressure fluctuations. An optional orifice prevents overspeeding. It raises supplied pressure to higher levels and compensates for oil consumption automatically, allowing precise outlet pressure adjustment by varying supplied pressure, ensuring efficient and controlled system performance.

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 PRV (pos. 5) and the internal check valves 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, the internal check valves 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.
