Product Description:
The Masoneilan SVI series valve positioners are advanced electro-pneumatic instruments created specifically for pneumatic control valves used in industrial automation systems. These devices are capable of interpreting 4-20mA analog signals as well as digital communication protocols like HART and FOUNDATION Fieldbus, enabling them to accurately adjust valve positions.
By maintaining precise control over valve positioning, the SVI series helps to ensure the consistent regulation of critical process variables, including flow, pressure, and temperature. This precise modulation is essential for optimizing industrial processes and maintaining product quality.
Equipped with high-precision sensors and powerful microprocessors, the valves utilize adaptive control algorithms to deliver reliable performance even in complex and demanding operating conditions. Furthermore, they support remote monitoring and diagnostic functions, allowing for enhanced control and maintenance capabilities from a distance.
Features:
High Precision Control
This device offers exceptional positioning accuracy within ±0.1% of the full scale. It also maintains hysteresis and deadband values at or below ±0.3%, guaranteeing consistent and reliable flow regulation under various operating conditions.
Smart Communication
Equipped with support for the HART protocol, including optional versions 5 and 7, the system seamlessly integrates with DCS and PLC platforms. This capability allows users to remotely configure parameters, access diagnostic data, and perform firmware upgrades conveniently via the ValVue software.
Modular Design
Designed with modularity in mind, key components like circuit boards and sensors can be quickly swapped out to lower maintenance expenses. Additionally, the device features a "one-touch tuning" function, which helps to minimize equipment downtime during adjustments.
Environmental Adaptability
Built to withstand harsh industrial environments, the device boasts an IP66/NEMA 4X protection rating. It operates reliably across a wide temperature range from -40°C to +85°C and tolerates humidity levels between 10% and 95% RH without condensation.
Explosion-Proof Certification
The product is certified by multiple international standards such as ATEX, IECEx, FM, and CSA. It supports explosion-proof designs (Ex d IIC T6) as well as intrinsically safe designs (Ex ia IIC T4), making it suitable for use in hazardous industrial environments.
Integrated Pressure Gauge
Certain models, including the SVi1000/PR/G/IM, feature integrated pressure gauges that allow for direct monitoring of input and output air pressures. This integration simplifies on-site commissioning and enhances operational efficiency.
