Description

The HC3-I is a variant of the HC3 providing high-pressure on the B port. It is designed for use in NG6 (D03) stacking manifold systems. The unit is compact weighing only 2.5 kg.

Maximum outlet pressure is 500 bar in standard versions. Adjustments of the outlet pressure is carried out by varying the supplied pressure.

Functions

The basic operation is illustrated in the function diagram. The oil is fed through the connecting plate to the control valve to the IN port of the HC3 flowing freely through check valves KV1, KV2 and DV to the high-pressure side H.

From the high-pressure side H, oil is fed to port B on the connecting plate. 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, valves KV1, KV2 and DV 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 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.

Ordering an HC3-I

Ordering example of an HC3 – I with i = 4.0, DV incorporated: HC3 – 4.0 – B – I

Attention note!
The G-model is available in 2 variants, when ordering please specify accordingly:

  • Dynamic – low hysteresis: Ordering example of an HC3 with i = 4.0 RV incorporated and BSPP connections: HC3 – 4.0 – G – I
  • Fail safe – high hysteresis: The RV valve opening ratio is to be determined on individual basis. Contact our technical support. Ordering example of an HC3 with i = 4.0 RV with opening ratio x.x incorporated and BSPP connections: HC3 – 4.0 – G – x.x – I
