Shop MiniBooster HC3-G Hydraulic Intensifiers with Direct Proportional Control
The miniBOOSTER HC3-G hydraulic intensifier, also called a hydraulic pressure booster, is a compact NG6 (D03) stacking-manifold unit with direct proportional RV pressure control. The RV valve allows high-pressure output at port A to be controlled proportionally from the low-pressure inlet side. HC3-G boosters are available in two variants: the standard G Dynamic model, which provides low hysteresis and fast response for applications such as hydraulic braking, and the G-__ Fail-Safe model, which uses higher hysteresis to keep high pressure stable until inlet pressure falls below approximately 50% of normal working pressure. The fail-safe version is suited to offshore safety circuits and other systems requiring controlled pressure retention and release without trapped high pressure. HC3 intensifiers offer ratios from 1.2:1 to 25:1, accept inlet pressures from 20 to 207 bar (290 to 3,000 psi), and produce outlet pressure up to 500 bar (7,250 psi), depending on the selected ratio.
The HC3-G integrates proportionally controlled high-pressure generation directly into an NG6/D03 valve stack, reducing external piping and eliminating the need for a separate high-pressure pump and control circuit. Applications include hydraulic braking, precision clamping and workholding, machine tools, testing equipment, industrial automation and offshore safety systems. Warning: The Dynamic G model requires stable inlet pressure and a supply line with a minimum inside diameter of 5 mm. Unstable inlet pressure, undersized lines, return backpressure or an incorrectly selected RV opening ratio can cause unreliable pressure control. The fail-safe G-__ variant must be selected for the specific application, with its RV opening ratio determined using qualified technical guidance. Never assume the high-pressure side has been relieved; verify zero pressure before service. All manifolds, valves, gauges, seals and actuators must be rated for the maximum possible intensified pressure.
