Product Description:
The Masoneilan SVI series valve positioners represent advanced electro-pneumatic technology specifically engineered for pneumatic control valves used in industrial automation systems. These intelligent devices interpret 4-20mA analog input signals as well as various digital communication protocols, including HART and FOUNDATION Fieldbus, to accurately adjust valve positions.
By precisely controlling the valve's position, the SVI series enables consistent regulation of critical process parameters such as flow rate, pressure, and temperature. This level of control helps maintain optimal performance and stability throughout different industrial processes.
Equipped with high-precision sensors and state-of-the-art microprocessors, the valve positioners utilize adaptive control algorithms to enhance responsiveness and accuracy. Additionally, the series offers capabilities for remote monitoring and diagnostics, allowing operators to ensure reliable operation even in challenging and complex conditions.
Features:
High Precision Control
The system offers exceptional positioning accuracy within ±0.1% of the full scale. It maintains hysteresis and deadband values at or below ±0.3%, which guarantees stable and precise flow regulation in various applications.
Smart Communication
Equipped with support for the HART protocol, including optional versions 5 and 7, this device ensures seamless compatibility with DCS and PLC systems. Users can remotely configure parameters, access diagnostic data, and perform firmware updates effortlessly through the ValVue software.
Modular Design
Key components such as circuit boards and sensors are designed for quick replacement, significantly reducing maintenance efforts and costs. The inclusion of "one-touch tuning" functionality further minimizes downtime, allowing for efficient system adjustments.
Environmental Adaptability
With an IP66/NEMA 4X protection rating, this device withstands harsh environmental conditions. It operates reliably within a temperature range from -40°C to +85°C and tolerates humidity levels between 10% and 95% RH (non-condensing), making it suitable for extreme industrial environments.
Explosion-Proof Certification
The product holds certifications from ATEX, IECEx, FM, CSA, and others. It supports explosion-proof configurations (Ex d IIC T6) as well as intrinsically safe designs (Ex ia IIC T4), ensuring safe operation in hazardous environments.
Integrated Pressure Gauge
Certain models, such as the SVi1000/PR/G/IM, feature built-in pressure gauges. These allow direct display of input and output air pressures, simplifying the commissioning process in the field and enhancing user convenience.

Applications
Petrochemical Industry
Valves are extensively utilized in refinery reactors and natural gas pipelines to ensure precise flow control of high-temperature and high-pressure substances such as crude oil and steam. These applications often occur in hazardous environments, demanding robust and reliable valve performance.
Power & Energy
In the power generation sector, valves play a critical role in regulating steam turbines, condensers, and boiler systems. Their ability to operate efficiently under high-temperature and vibration conditions contributes significantly to optimizing the overall efficiency of power plants.
Water Treatment
For municipal water supply and wastewater treatment facilities, valves assist in managing large-diameter flow control. They help optimize the distribution of water as well as the precise dosing of chemicals necessary for water purification processes.
Pharmaceutical & Food Processing
These industries demand strict hygienic standards. Valves used here are designed for sterile valve control within cleanroom environments, ensuring that production maintains safety and cleanliness throughout the manufacturing process.
Metallurgical Industry
In metallurgical applications, valves provide accurate regulation of atmospheric conditions and fluid transfer during smelting operations. Their capability to function continuously under high-temperature and high-pressure environments supports uninterrupted industrial processes.
