Product Information

bullet Proven dependability
bullet Ideally suited for automated or computer controlled systems
bullet Wide range of optional features and related control equipment
bullet Feature for feature, the most economical high performance electric actuators on the market CSA approved models

These RCS actuators have rugged, high-torque, integral, single-phase, reversible capacitor run motors and are equipped with travel limit switches which are factory set for O deg. to 90 deg. Other settings from O deg. to 360 deg. and multi-turn are available.

All units are ideally suited for automated and computer controlled systems and will accommodate all of the new RCS solid state controls.

Models MAR100, 120, 160, 250 and  800 have an electrical lock-out switch to prevent electrical operation while handwheel is engaged.

These units feature rugged, high-torque, integral, single phase, reversible, capacitor run motor Actuators are equipped with travel limit switches which are factory set for O deg. to 90 deg. Other settings from O deg. to 360 deg and multi-turn are available.

All units are ideally suited for automated and computer controlled systems and will accommodate all of the new RCS solid state controls.

These actuators are designed for ball valves 3 inches through 8 inches, butterfly valves from 8 inches through 20 inches and plug valves through 16 inches.

 Applications

bullet Ball, butterfly, plug and choke valves
bullet Dampers, power switches, safety and flow monitoring devices
bullet Automatic door and braking operations
bullet Machine and fixture indexing
bullet Combined with optional RCS DigilineTM products, these actuators can perform an almost limitless range of functions, including multi-turn applications and precision process control operations
