CVP2000-3
The CVP2000-3 Compact Flameproof Valve Positioner is a high-performance intelligent control device engineered for EPC contractors, plant operators, and industrial system integrators requiring robust valve control in high-risk hazardous areas. Delivering comprehensive flameproof protection (Ex db/ia/tb) and TÜV SIL2 certification, this positioner packs enterprise-grade functionality into a compact, lightweight footprint (205×141×155.5mm, 2.9kg), making it the ideal solution for space-constrained installations without compromising safety or performance. Supporting APL, HART, and FF communication protocols, it integrates seamlessly with existing industrial automation systems, while its -40°C rated OLED display and built-in predictive maintenance features deliver unmatched operational reliability in harsh industrial environments. Designed to regulate control valve opening with precision, it sets a new standard for flameproof valve positioners for hazardous areas with low air consumption, modular maintainability, and industry-leading safety credentials.
At the core of this SIL2 certified valve positioner is its comprehensive flameproof certification (Ex db/ia/tb), validated to meet the strictest global standards for operation in explosive hazardous areas. Unlike bulkier flameproof models, it delivers full safety protection without sacrificing installation flexibility.
With a footprint of just 205×141×155.5mm and 2.9kg total weight, this compact flameproof valve positioner solves a critical pain point for facilities with limited valve mounting space. Its streamlined form factor fits into tight enclosures while retaining all functionality of larger flameproof models.
Equipped with a standard pressure gauge module for continuous supply and output pressure monitoring, the positioner enables full predictive maintenance without external sensors. Its rugged OLED display operates reliably at temperatures as low as -40°C, ensuring full control in extreme cold environments.
With a steady state air consumption of less than 0.024Nm³/h, this low air consumption valve positioner minimizes compressed air usage, a major ongoing industrial expense. Its high flow rates ensure fast, responsive valve actuation without unnecessary air waste.
