Product Description:
The Masoneilan SVI series valve positioners are advanced electro-pneumatic devices engineered specifically for use with pneumatic control valves in industrial automation systems. These intelligent positioners are capable of receiving 4-20mA analog signals as well as digital communication protocols, including HART and FOUNDATION Fieldbus, to accurately manage valve positioning.
By precisely controlling the valve positions, the SVI series helps maintain stable regulation of critical process parameters such as flow, pressure, and temperature. This ensures optimal performance and enhances the reliability of automated processes within various industrial environments.
Equipped with high-precision sensors, embedded microprocessors, and adaptive control algorithms, these valve positioners offer sophisticated functionality. They also provide capabilities for remote monitoring and diagnostics, enabling effective and precise control even under complex and demanding operating conditions.
Features:
High Precision Control
The system offers an outstanding positioning accuracy within ±0.1% of the full scale. It maintains hysteresis and deadband values at or below ±0.3%, which guarantees precise and stable flow regulation under various operating conditions.
Smart Communication
Equipped with support for the HART communication protocol, available in versions 5 and 7, this device seamlessly integrates with DCS and PLC systems. It allows for remote parameter adjustments, diagnostic data retrieval, and firmware updates through ValVue software, enhancing operational efficiency and ease of management.
Modular Design
The product features a modular construction allowing for the rapid replacement of key components such as circuit boards and sensors. This approach significantly reduces maintenance expenses. Additionally, the inclusion of a "one-touch tuning" function helps minimize system downtime during servicing.
Environmental Adaptability
Designed to withstand harsh industrial environments, the device has an IP66/NEMA 4X protection rating. It operates efficiently across a wide temperature range from -40°C to +85°C and can tolerate relative humidity levels between 10% and 95% (non-condensing), ensuring reliable performance in extreme conditions.
Explosion-Proof Certification
The product is certified by leading standards organizations including ATEX, IECEx, FM, and CSA. It supports explosion-proof designs identified as Ex d IIC T6 as well as intrinsically safe configurations designated Ex ia IIC T4, making it suitable for use in hazardous and potentially explosive atmospheres.
Integrated Pressure Gauge
Certain models, such as the SVi1000/PR/G/IM, come equipped with built-in pressure gauges that display input and output air pressure directly. This feature simplifies field commissioning by providing immediate, on-site pressure readings without the need for additional instruments.
