Overspeed control system CTo

protectionfor electrical applicationspositioning

The Voith CTo overspeed protection system consists of an electronic signal pro­cessing unit that detects overspeed and an electrohydraulic assembly that actuates a hydraulic positioning cylinder directly. This positioning cylinder opens or closes a trip valve that releases or blocks the mass flow needed to drive machinery. The CTo is a compact assembly and is intended for direct mounting to the actuator of the trip valve. This keeps signal paths short, making the unit immune to inter­ference. The CTo features a simple design. This ensures reliable operation. The Mean Time Between Failures (MTBF) for the Voith CTo is over 200 years.
