RCS Actuators

FloSource is an stocking Distributor for RCS electric actuators. Since 1966 RCS has been making electric quarter turn actuators in America. RCS electric actuators can be found in the most challengining and demanding environments including: Oil & Gas, Water & Wastewater, Power Generation, Pulp & Paper, Steel Processing, Aluminum Processing, Chemical, Automotive, and Tunnel Ventilation. These units offer the end user a long service life, outstanding value, and a custom solution when required. RCS makes electric actuators in 2 distinct styles. The traditional type and a spring return electric design. FloSource has years of experience with both. Outlined below and the attached links the end user should find information that will help in the selection of unit. Please contact us for assistance.

All RCS electric actuators are powered by an extended duty, high-torque, reversible motor. These motors are suitable for both on/off and modulat- ing applications, with many models rated for extended duty. Each motor is Class “B” insulated and has an internal thermal overload protective device. This device protects the motor if a “stall” condition occurs thus preventing the motor from overheating which results in premature motor failure.
Permanent Lubrication. Each gear and spring assembly is permanently lubricated with a high quality lubricant selected to meet a wide range of operational and environmental conditions. Periodic lubrication is not required.

Versatile Installation. All RCS actuators can be installed and operated in any position. This allows flexibility for installation in confined locations or in retrofit applications

Manual Override. MAR/DCR10, 50 and 90 models feature a declutchable manual override. The actuator gearing is disengaged from the motor thus the actuator cannot be operated electrically while in manual operation. MAR100 through 4000 feature a manual override with an automatic electrical safety lockout switch. When the handwheel is engaged, the electrical switch isolates the motor from the supply voltage to prevent electrical operation.

Environmental. With electroless nickel plated output shafts and stainless steel external bolting, RCS actua- tors will stand up to a broad range of environmental conditions. Optional marine epoxy paint systems or electroless nickel plated enclosures are also available to meet most onshore or offshore conditions.

Position Indication. Mechanical position indicators are standard on every model. These devices provide an external position reference for the actuator or driven equipment
