Product Description:
The Masoneilan SVI series valve positioners are advanced electro-pneumatic devices created specifically for use with pneumatic control valves within the realm of industrial automation. These intelligent positioners receive input signals in the form of 4-20mA analog signals or various digital communication protocols, including HART and FOUNDATION Fieldbus. This allows them to accurately adjust valve positions to maintain optimal control.
By ensuring precise valve positioning, the SVI series helps achieve stable regulation of critical process parameters such as flow rate, pressure levels, and temperature. This precise control is essential for maintaining the safety, efficiency, and reliability of industrial processes.
The design of the Masoneilan SVI series incorporates high-precision sensors combined with powerful microprocessors and advanced adaptive control algorithms. These features enable the devices to perform exceptionally well even under complex and demanding operating conditions. Furthermore, the series supports remote monitoring and diagnostic capabilities, which facilitate proactive maintenance and enhance overall system performance.
Features:
High Precision Control
The device offers exceptional positioning accuracy within ±0.1% of the full scale. Additionally, it maintains hysteresis and deadband values at or below ±0.3%, guaranteeing stable and reliable flow regulation throughout its operation.
Smart Communication
It supports the HART communication protocol, with optional versions 5 and 7 available. This compatibility ensures seamless integration with DCS and PLC systems, allowing users to remotely configure parameters, access diagnostic data, and perform firmware updates using the ValVue software platform.
Modular Design
The product features a modular design that enables quick replacement of key components, such as circuit boards and sensors. This approach effectively reduces maintenance costs and downtime. Furthermore, the inclusion of a "one-touch tuning" feature facilitates rapid adjustments for enhanced operational efficiency.
Environmental Adaptability
Designed to withstand harsh industrial environments, the device has an IP66/NEMA 4X protection rating. It operates reliably within a wide temperature range of -40°C to +85°C and tolerates humidity levels from 10% to 95% RH, provided there is no condensation.
Explosion-Proof Certification
The product is certified by renowned safety standards including ATEX, IECEx, FM, and CSA. It supports explosion-proof designs (Ex d IIC T6) as well as intrinsically safe configurations (Ex ia IIC T4), making it suitable for use in hazardous environments requiring stringent safety measures.
Integrated Pressure Gauge
Certain models, such as the SVi1000/PR/G/IM, come equipped with integrated pressure gauges. These gauges provide direct readings of input and output air pressure, simplifying the process of field commissioning and enhancing user convenience.
