CVA range linear and part-turn precision modulating actuators provide an electrically powered process control operator suitable for most control valve types and sizes. Designed for continuous, unrestricted modulation to S9 (IEC 60034), Class D duty (ISO 22153) with watertight IP68, NEMA 4 & 6, and explosionproof enclosures, the CVA sets a new standard for process control accuracy and valve actuation. High reliability and ultra-low energy consumption mean CVA is perfectly suited for solar-powered applications in remote locations. Comprehensive control valve performance information is delivered to the user via the built-in data logger for asset management and predictive maintenance software analysis.
