Electric Actuator - Modulating Range | Bernard Controls

The Electric Actuator - Modulating Range by Bernard Controls is designed for seamless integration with all types of modulating valves, including quarter-turn, multi-turn, and linear configurations. It offers two types of controls: an electromechanical switch and the advanced Integrated INTELLI+®(v2) system. Classified under BC Duty & Modulating as Class II for continuous modulating per EN15714-2 Class D, this actuator is built to withstand harsh environments with an IP 68 rating and temperature tolerance from -20°C to +60°C, with an optional low-temperature version down to -40°C. Explosion-proof versions (SQXM/STXM) are also available. Bernard Controls leverages its extensive expertise in continuous modulating applications to provide solutions that meet rigorous performance criteria, including resolution, dead band, response time, and linearity, ensuring precise and reliable operation tailored to specific process requirements.

PRODUCT BENEFITS

BERNARD CONTROLS’ PROVEN EXPERTISE FOR CONTINUOUS MODULATING

EN15714-2 Standard defines a duty classification for an electric actuator to operate the valve: On-Off, Inching/Positioning, Modulating and Continuous modulating. This duty classification defines basic design requirements. However, in order to define practically and precisely the appropriate solution corresponding to your own process requirements, you need to qualify each duty type with key criteria.

Modulating applications require specific expertise to define the most appropriate solution. Duty PERFORMANCE is the main criterion to fully address process requirements, but needs to be specified and completed with additional performance criteria, notably RESOLUTION.

For many years, BERNARD CONTROLS has been a leader in these applications. Our modulating classification is now well-know from our customers and has, in fact, inspired the European Norm EN15714-2. Therefore, BERNARD CONTROLS chooses to set key additional performance criteria – RESOLUTION / Dead band / Response Time / Linearity – to determine end-users’ solution.
