Sizing a Reservoir
A system with a single acting cylinder, power up/gravity down, requires enough fluid in the reservoir to fill the cylinder when fully extended. A double acting cylinder, power up/power down, requires a much smaller reservoir because fluid is transferred from one side of the cylinder piston to the other as it extends and retracts. Call our sales department with the bore and stroke of your cylinder and we’ll size the correct reservoir saving you space and money.
