Milwaukee Cylinder Dual-Pressure Booster Model BA

In Milwaukee Cylinder's Model BA Booster, the high pressure output is applied only after the ram has entered the secondary, or high pressure seal. This allows a low pressure approach stroke and a high pressure work stroke where the working ram travels only a short distance under high pressure, as when a part needs to be clamped in position for another operation. Model BA boosters are self bleeding and an external valve in the inlet is not required. RAPID TRAVERSE, AUTOMATIC SEQUENCING WITH BA BOOSTER Below the circuit shows the use of a double-acting cylinder with rapid traverse at low pressure and sequencing to high pressure when the load is picked up. When the air valve is shifted, the left air-oil tank forces oil through the booster and extends the cylinder. When the load is picked up, the timer valve ports air to the booster for a high pressure output to the cylinder. On the return stroke, the right air-oil tank retracts the cylinder.
