LN81 Series Single - Seat Control Valve and Masoneilan SVI2 Valve Positioner
Product Introduction
The LN81 series single - seat control valve, a key device for industrial fluid control, precisely regulates parameters such as fluid flow rate and pressure by driving the valve core to move linearly through the valve stem. With its single - core and single - seat design, it offers excellent sealing performance, with a standard leakage rate ≤0.01% of the rated flow coefficient, suitable for strict shut - off requirements. The Masoneilan SVI2 valve positioner, with a microprocessor at its core, accurately converts control signals into pneumatic signals to drive the control valve and monitors the valve stem displacement in real - time to ensure precise opening. Together, they provide a reliable fluid control solution for industrial production.
Features
- Precise Control: The SVI2 positioner enables the LN81 control valve to achieve high - precision adjustment with an accuracy of ±0.5%, ensuring stable production.
- Rapid Response: Reduces signal lag and accelerates valve stem movement, quickly responding to control commands to meet dynamic adjustment needs.
- Strong Adaptability: The LN81 control valve features a simple structure for easy maintenance, while the SVI2 positioner supports multiple communication protocols and adapts to various industrial environments. The combination can handle complex working conditions.
Applications
Widely used in industries such as chemical, oil and gas, power, water supply, and sewage treatment, it precisely controls various fluid media to ensure stable and efficient process operation.
