HC225 versions: 15 different intensification factors
PIN: 20 – 207 bar
PH: 800 bar maximum
PRETURN: As low as possible (return pressure to tank)
POUTLET: PH = (PIN – PRETURN) x i (intensification)
Mounting: Inline tube
Weight: 3.0 kg. / 3.3 kg.
The HC225 is a compact unit weighing max. 3.3 kg. It is ideal for use in a variety of applications where building and maintaining high pressure is required.
The HC225 incorporates both a counterbalance valve and a pressure reducing valve (PRV).
The integrated counterbalance valve 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. Then the counterbalance valve opens, and the booster starts oscillating.
The integrated pressure reducing valve controls inlet pressure to the booster section. It protects both booster and high-pressure tool against too high pressure. It secures a stable high pressure regardless of changes in the tank line pressure.
An optional orifice can be mounted in the R-port of the booster to prevent overspeeding.
The HC225 raises supplied pressure to a higher outlet pressure and automatically compensates for oil consumption to maintain the high pressure. Adjustment of the outlet pressure is carried out by varying the supplied pressure.
|Max. intensified outlet flow|
|Max. inlet flow|
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.
