Product Description:
The Masoneilan SVI series valve positioners represent advanced electro-pneumatic devices specifically engineered for use with pneumatic control valves in the field of industrial automation. These positioners are capable of receiving 4-20mA analog input signals as well as various digital communication protocols, including HART and FOUNDATION Fieldbus.
By accurately interpreting these signals, the SVI series ensures precise manipulation of valve positions, which is critical for maintaining stable control over essential process parameters such as flow, pressure, and temperature. This precise regulation helps optimize the overall efficiency and reliability of industrial processes.
Incorporating high-precision sensors, powerful microprocessors, and adaptive control algorithms, the SVI series offers robust performance even in complex operating environments. Furthermore, these devices support remote monitoring and diagnostic capabilities, enabling operators to maintain optimal control and quickly respond to any anomalies from a distance.
Features:
High Precision Control
The device offers an outstanding positioning accuracy of ±0.1% of the full scale. It maintains hysteresis and deadband values within ±0.3%, ensuring precise and stable regulation of flow.
Smart Communication
Equipped with support for the HART protocol, available in versions 5 and 7, this product seamlessly integrates with DCS and PLC systems. It facilitates remote configuration of parameters, reading of diagnostic data, and firmware upgrades through the ValVue software.
Modular Design
Key components such as circuit boards and sensors are designed for quick replacement, significantly reducing maintenance expenses. Additionally, the "one-touch tuning" feature helps minimize downtime during servicing.
Environmental Adaptability
With an IP66 and NEMA 4X protection rating, the product is built to withstand harsh conditions. It operates reliably across a wide temperature range from -40°C to +85°C and tolerates humidity levels between 10% and 95% relative humidity, non-condensing, making it ideal for extreme industrial environments.
Explosion-Proof Certification
Certified by renowned authorities including ATEX, IECEx, FM, and CSA, the product supports explosion-proof designs (Ex d IIC T6) and intrinsically safe designs (Ex ia IIC T4), ensuring safety and compliance in hazardous locations.
Integrated Pressure Gauge
Certain models, like the SVi1000/PR/G/IM, come equipped with integrated pressure gauges. These gauges provide a direct display of the input and output air pressure, simplifying the process of field commissioning.
