The electro-hydraulic Power Drive is a closed-loop, self contained unit used for controlling dampers and valves. The electro-hydraulic Power Drive is available in both rotary and linear models and includes such standard features as limit switches, manual overrides and a variety of voltages. The electro-hydraulic Power Drive goes through a rigorous testing process in our Loveland Ohio facility and are machined to required dimensions, holding design tolerances.

Power Drive® Features

• The mounting hardware, support column, and lever arm are made from carbon steel or stainless steel.
• The drive shaft is stainless steel and is supported by flanged ball bearings.
• The lever arm is infinitely adjustable, both radially and axially.
• Teflon tubing is shielded with braided stainless steel. The fittings are stainless steel.
• Field retrofits are designed to match the critical dimensions of the old drive unit. Remove the old unit, bolt in and connect the Power Drive.
• The control characteristic has superior positioning accuracy, typically within ¼ % of supply signal.
• Torque output up to 14,000 ft-lbs

Power Drive® Design

• The Power Drive design assures high quality and structural soundness.
• Lower torque output units utilize a stand design, while large units have a frame design.
• Each design is modeled in a 3D modeling program.
• The stainless steel drive shaft is supported by bearings, to prevent actuator side loading.
• The lever arm position is infinitely adjustable through the use of the shaft locking device.
• The design of the field retrofit unit ensures exact interchangeability with the unit being replaced.
• This design significantly simplifies the change out. Merely unbolt and disconnect the linkage and power of the old unit, inspect the linkage for reuse, then simply install the new Power Drive.
