Description

The HC6DW is a high flow dual-acting stainless steel 316 L unit which is capable of delivering up to 47.1 l/min flow on the high-pressure end. Like other miniBOOSTER models, the HC6DW raises supplied pressure to a higher outlet pressure and automatically compensates for consumption of oil to maintain the high pressure.

Adjustment of the outlet pressure is carried out by varying the supplied pressure. Relative to its flow capability, the HC6DW is a compact unit weighing 34.8 kg.

Functions

The basic operation is illustrated in the function diagram. Oil is fed through the directional valve CV to the IN port, flowing freely through the check valves 2x KV1, 2x KV2 and DV 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, valves KV1, KV2 and DV will close. The end pressure will be achieved by the oscillating pump units OP1 and OP2 by turns. 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 OP1 and OP2 units will automatically operate to maintain the end pressure. It is possible to change the high-pressure connection H to the opposite end of the booster.

Ordering an Ordering an HC6DW

HC6DW-…………..: with Bypass Valve (BPV) without Sequence Valve and Pressure Reducing Valve

HC6DWA-………..: with Bypass Valve (BPV) with Sequence Valve and Pressure Reducing Valve

HC6DWB-………..: without Bypass Valve (BPV) without Sequence Valve and Pressure Reducing Valve

Ordering example of an HC6DW with i = 4.0, DV incorporated, BSPP connections and H-PUR dynamic seals:

HC6DW – 4.0 – B – 1HH for media < 5 cSt (mm2/s) tested in water
HC6DW – 4.0 – B – 1SHH for media > 5 cSt (mm2/s) tested in hydraulic oil

Attention notes!
High-pressure adapter is required, please specify ordering code – see high-pressure adapter table.
High-pressure adapters will be factory mounted.

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

  • Dynamic – low hysteresis: Ordering example of an HC6DW with i = 4.0 RV incorporated, BSPP connections and H-PUR dynamic seals: HC6DW – 4.0 – G – 1SHH
  • Fail safe – high hysteresis: The RV valve opening ratio is to be determined on individual basis. Contact our technical support. Ordering example of an HC6DW with i = 4.0 RV with opening ratio x.x incorporated, BSPP connections and H-PUR dynamic seals: HC6DW – 4.0 – G – x.x – 1HH
