REXA’s two REXA MEGApac Rotary Electraulic™ Actuators have been commissioned into production for slurry isolation control on severe service ball valves at a nickel processing plant in Palawan, Philippines.
These MEGApac Rotary Electraulic™ Actuators, which replaced underperforming pneumatic actuators, are specifically designed to withstand the harsh High Pressure Acid Leach (HPAL) service – a technology that enables the recovery of nickel metal from laterite ores that traditionally were difficult to process. The MEGApacs use 400,000 in. lbs. of torque and rapid speeds to turn severe service ball valves 90 degrees in under ten seconds for reliable slurry isolation control.
Electraulic™ actuators and drives offer a self-contained, positive pressure, hermetically sealed system that requires minimal power consumption. There are no filters, large reservoirs or routine oil maintenance needed.
