The HC3 - H is a variant of the HC3 with the topside and the B port closed, not needing a top plate. It is designed for use in NG6 (D03) stacking manifold systems. Like the other HC3 units, the HC3-H is a compact unit. The HC3 has the pilot-operated dump valve incorporated as a standard feature. Maximum outlet pressure is 500 bar in standard versions. Adjustments of the outlet pressure is carried out by varying the supplied pressure.
The basic operation is illustrated in the function diagram. The oil is fed through the connecting plate and the filter 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 A 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.

Without Dump Valve
High pressure is relieved externally. This is achieved in most cases by the use of a pilot operated check valve.
With Dump Valve
Allows the high pressure side to be relieved. When port 'R' is pressurised and port 'IN' is open to tank.
With RV Valve
The RV valve allows you to control the high-pressure side proportionally controlled directly from the low-pressure side.
As shown in the chart Minibooster has a dual flow/pressure feature. Initially when fluid is supplied to the booster it flows straight through to the high pressure side. At this point all the supplied flow (up to the max. allowed inlet flow) goes to the actuator allowing it to operate fast in the desired direction. As soon as inlet pressure is reached in the actuator, the flow will then be supplied via the high pressure piston until intensified pressure is reached.

Typical clamping circuit
0-103 Model - Example with single-acting cylinder
The HC2 is used to boost the pressure in an existing hydraulic circuit, e.g. in a machining centre to ensure a sufficient clamping force. As the HC2 can be directly fitted into the workholding system, high-pressure connections can be avoided.
Applications with larger flowrates
0-104 Model - Example with external pilot-operated check valve
In applications where the pump supplies a flow exceeding the maximum permissible supplied flow to the HC2, the HC2 is installed in parallel with a pilot-operated check valve. This check valve is dimensioned to allow for all the flow supplied from the pump. The inlet flow to the HC2 is limited to the maximum permissible flow for the particular intensification ratio.
As the cylinder moves forward, all the flow from the pump is used. When the pump pressure is established in the cylinder the check valve closes, and the end pressure builds up through the HC2. The cylinder is retracted by changing the position of the directional valve, whereby the pump is connected to the other side of the cylinder and the DV opens, allowing the fluid to return to the tank.
