Shop MiniBooster HC6-G Hydraulic Intensifiers with Direct Proportional Control
The miniBOOSTER HC6-G hydraulic intensifier, also called a hydraulic pressure booster, is a high-flow inline unit with direct proportional RV pressure control. The RV valve allows high-pressure output to be controlled proportionally from the low-pressure inlet side. HC6-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. The HC6 family offers nine intensification ratios from 1.3:1 to 8.2:1, accepts inlet pressures from 20 to 207 bar (290 to 3,000 psi), and produces outlet pressures up to 800 bar (11,600 psi), with intensified flow up to 28.3 L/min (7.5 GPM), depending on the selected ratio.
The HC6-G supplies proportionally controlled high pressure at substantial flow without requiring a separate high-pressure pump or control circuit. Applications include hydraulic braking, heavy-duty clamping and workholding, presses, large cylinders, pressure-testing equipment, mobile machinery, 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, excessive return backpressure or an incorrectly selected RV opening ratio can cause unreliable pressure control. The fail-safe G-__ variant must be specified for the 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 hoses, fittings, valves, gauges, seals, manifolds and actuators must be rated for the maximum possible intensified pressure, and installation must be performed by qualified hydraulic personnel.
