Product Description:
The Masoneilan SVI series valve positioners are advanced electro-pneumatic devices specifically engineered for controlling pneumatic valves within industrial automation systems. These intelligent positioners accept 4-20mA analog input signals as well as various digital communication protocols, including HART and FOUNDATION Fieldbus, to accurately adjust valve positions.
By precisely managing valve movements, the SVI series ensures stable and reliable regulation of critical process variables such as flow rate, pressure, and temperature. This functionality is essential for maintaining optimal performance and safety across diverse industrial applications.
Moreover, the valve positioners incorporate high-precision sensors and powerful microprocessors, combined with adaptive control algorithms. This integration allows for enhanced control accuracy and responsiveness. In addition, the SVI series supports remote monitoring and diagnostic capabilities, enabling users to oversee valve performance and troubleshoot issues effectively even under complex operating conditions.
Features:
High Precision Control
This product offers outstanding positioning accuracy, achieving ±0.1% of full scale. It maintains a hysteresis and deadband within ±0.3%, which guarantees stable and reliable flow regulation under various operating conditions.
Smart Communication
Equipped with support for the HART protocol, including optional versions 5 and 7, this device seamlessly integrates with DCS and PLC control systems. It allows users to perform remote configuration of parameters, access diagnostic data, and update firmware conveniently through the ValVue software platform.
Modular Design
The modular design facilitates quick replacement of essential components such as circuit boards and sensors, significantly lowering maintenance costs. Additionally, the "one-touch tuning" feature ensures that downtime is minimized, enhancing overall operational efficiency.
Environmental Adaptability
Built to withstand harsh industrial environments, the product carries an IP66/NEMA 4X protection rating. It operates reliably across a wide temperature range from -40°C to +85°C and can tolerate humidity levels between 10% and 95% relative humidity without condensation.
Explosion-Proof Certification
The device is certified by multiple authoritative bodies including ATEX, IECEx, FM, and CSA. It supports explosion-proof configurations (Ex d IIC T6) as well as intrinsically safe designs (Ex ia IIC T4), making it suitable for use in hazardous atmospheres where safety is paramount.
Integrated Pressure Gauge
Certain models, such as the SVi1000/PR/G/IM, come equipped with an integrated pressure gauge. This feature allows for the immediate display of input and output air pressure, simplifying field commissioning and enhancing user convenience.
