About Bernard Controls

Bernard Controls is a manufacturer of electric actuators (servomotors) for valves. The products are based on a worm gear transmission (roue et vis sans fin) that combines a high gear ratio with self-locking. The portfolio includes intelligent integrated controls (INTELLI+), absolute sensors for position and torque, limit switch systems with a patented cam block, torque limiters, manual emergency operation as well as functions such as emergency shutdown (ESD), fieldbus connectivity and SIL-compliant design. The motors are designed as asynchronous motors with high starting torque and are specified according to duty cycle S4 (IEC 60034). The group maintains locations in Europe, Asia, the Middle East, America and Australia. Core markets are the nuclear industry as well as oil and gas.
