Product Description:
The Masoneilan SVI series valve positioners represent advanced electro-pneumatic devices engineered specifically for pneumatic control valves used in industrial automation. These positioners are capable of receiving 4-20mA analog signals as well as digital communication protocols such as HART and FOUNDATION Fieldbus, allowing for highly accurate valve positioning.
By precisely controlling valve positions, the SVI series helps maintain stable regulation of crucial process parameters including flow, pressure, and temperature. This precision contributes significantly to improving the overall efficiency and reliability of automated industrial systems.
Equipped with high-precision sensors, powerful microprocessors, and sophisticated adaptive control algorithms, the SVI valve positioners offer enhanced performance. Additionally, they support remote monitoring and diagnostic capabilities, enabling operators to achieve precise control even under challenging and complex operating conditions.
Features:
High Precision Control
The device offers exceptional positioning accuracy at ±0.1% of the full scale. It maintains stability in flow regulation by keeping hysteresis and deadband within ±0.3%, ensuring reliable performance in various applications.
Smart Communication
Supporting the HART protocol with optional versions 5 and 7, this equipment is fully compatible with DCS and PLC systems. It allows for remote configuration of parameters, access to diagnostic information, and firmware upgrades through the ValVue software platform.
Modular Design
The modular architecture permits quick replacement of critical components such as circuit boards and sensors, thereby reducing maintenance costs. Additionally, the device features a "one-touch tuning" function that helps minimize downtime during operation.
Environmental Adaptability
Designed to operate in harsh industrial conditions, the device boasts an IP66/NEMA 4X protection rating. It can function within a wide temperature range from -40°C up to +85°C and tolerates humidity levels between 10% and 95% RH without condensation.
Explosion-Proof Certification
Equipped with certifications from ATEX, IECEx, FM, CSA, and more, the product supports explosion-proof designs (Ex d IIC T6) as well as intrinsically safe configurations (Ex ia IIC T4). This makes it suitable for use in hazardous environments.
Integrated Pressure Gauge
Certain models, including the SVi1000/PR/G/IM, come with built-in pressure gauges. These gauges provide direct readings of input and output air pressure, greatly simplifying the commissioning process in the field.
