Masoneilan SVI2 Valve Positioner: A Precise Partner for Industrial Fluid Control
Product Introduction
The Masoneilan SVI2 valve positioner is an intelligent digital valve positioning device that plays a crucial role in the field of industrial automation. With a 32 - bit microprocessor at its core, it accurately controls the pneumatic actuator through a two - wire 4 - 20mA control signal to precisely adjust the opening of the valve. This positioner uses advanced non - contact Hall - effect sensors to monitor the valve stem position in real - time and feedback the adjustment signal, ensuring accurate valve positioning. In addition, with the HART communication protocol, the SVI2 has two - way communication capabilities, which is convenient for integration with various control systems to achieve remote monitoring and parameter adjustment.
Features
High - Precision Positioning: With adaptive PID algorithms and fuzzy logic controllers, the positioning accuracy can reach ±0.1%. It can customize curves according to valve characteristics and effectively compensate for flow deviations caused by factors such as changes in medium viscosity, ensuring precise and stable fluid control.
Long - Life Design: The non - contact position sensing technology avoids mechanical moving parts from entering the main housing cavity, reduces wear and tear, significantly extends the service life of the equipment, and reduces maintenance costs.
Multiple Communication Support: It supports multiple communication protocols such as HART 7.0, PROFIBUS - PA, and FOUNDATION Fieldbus, and can be easily connected to different control systems to meet the needs of diverse industrial scenarios.
Intelligent Diagnostic Function: It collects more than 20 parameters such as valve friction, air source pressure, and coil temperature in real - time, generates an equipment health index (0 - 100 points), and warns in advance of faults such as valve sticking and air source leakage. The predictive maintenance accuracy is as high as 92%, ensuring production continuity.
Convenient Operation: It is equipped with an LCD display and buttons and can be operated in certified hazardous environments. It has automatic stop and automatic tuning functions, which can quickly and accurately complete the debugging and reduce the operation difficulty.
Strong Environmental Adaptability: It has passed explosion - proof certifications such as ATEX Zone 1/21 and IECEx and is suitable for inflammable and explosive hazardous environments. Its protection level reaches IP66/IP67, which is dust - proof and waterproof and can operate stably in harsh industrial environments.
Applications
Oil and Gas Industry: In the oil and gas exploration, transportation, and processing sectors, high precision and safety are required for fluid control. The SVI2 valve positioner can accurately regulate various valves, ensuring the safe and efficient transmission of oil and gas, preventing leaks, and guaranteeing smooth production.
Chemical Industry: Chemical production involves many corrosive and dangerous media. This positioner can reliably regulate the flow of chemicals in chemical pipelines, ensuring the stability of the chemical production process and is widely used in fields such as petrochemicals, fine chemicals, and chemical pharmaceuticals.
Power Industry: During power generation, it is necessary to accurately control the flow of media such as steam, water, and fuel. The SVI2 valve positioner helps related valves achieve precise control, ensuring the stable operation of power generation equipment and improving energy conversion efficiency. It is suitable for various power generation scenarios such as thermal power, hydropower, and nuclear power.
Water Supply and Sewage Treatment Systems: In urban water supply and sewage treatment systems, precise control of water flow and pressure is crucial. The SVI2 positioner enables precise control of water pumps, valves, and other equipment, ensuring stable water supply, normal water pressure, optimizing the sewage treatment process, and improving water resource utilization efficiency.
