Product Description:
The Masoneilan SVI series valve positioners represent advanced electro-pneumatic devices specifically engineered 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 adjust valve positions.
By precisely controlling valve movements, the SVI series helps maintain stable regulation of crucial process parameters such as flow, pressure, and temperature. This ensures optimized performance and improved efficiency in various industrial applications.
Equipped with high-precision sensors, integrated microprocessors, and sophisticated adaptive control algorithms, the valve positioners offer reliable and consistent operation. Furthermore, the series supports remote monitoring and diagnostics, enabling operators to achieve precise control even under complex and challenging operating conditions.
Features:
High Precision Control
The system guarantees positioning accuracy within ±0.1% of the full scale, accompanied by hysteresis and deadband values kept at or below ±0.3%. This high level of precision ensures consistent and stable flow regulation throughout operation.
Smart Communication
Supporting the HART protocol (with optional versions 5 or 7), the device seamlessly integrates with DCS and PLC systems. This capability allows for remote parameter adjustments, easy retrieval of diagnostic data, and straightforward firmware updates through the ValVue software platform.
Modular Design
Designed with a modular approach, critical components such as circuit boards and sensors can be swiftly replaced, significantly cutting down maintenance expenses. Additionally, the "one-touch tuning" feature helps minimize equipment downtime.
Environmental Adaptability
Boasting an IP66/NEMA 4X protection rating, the device operates reliably in harsh conditions with temperatures ranging from -40°C to +85°C. It also tolerates humidity levels between 10% and 95% RH (non-condensing), making it suitable for extreme industrial environments.
Explosion-Proof Certification
The product is certified by multiple recognized authorities including ATEX, IECEx, FM, and CSA. It supports both explosion-proof (Ex d IIC T6) and intrinsically safe (Ex ia IIC T4) designs, ensuring safe use in hazardous and potentially explosive environments.
Integrated Pressure Gauge
Certain models, such as the SVi1000/PR/G/IM, feature built-in pressure gauges. This integration allows for the direct display of input and output air pressure, greatly simplifying field commissioning and ongoing monitoring.
