Product Description

The HC425 – 1.3 – B – 1, weighing just 5.5 kg/ 12.1 lbs, is an ideal solution for applications requiring high-pressure maintenance. Featuring both a counterbalance valve and a pressure reducing valve (PRV), it ensures swift cylinder movement and controls inlet pressure to protect the booster and high-pressure tools. An optional orifice prevents overspeeding. This compact unit raises supplied pressure to a higher outlet pressure, automatically compensating for oil consumption. Outlet pressure adjustment is achieved by varying the supplied pressure, guaranteeing stable high pressure regardless of tank line pressure changes.

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.
