Symmetrical Membrane Valve Smart Valve Positioner With Nozzle Baffle C41FY-LSA
Nozzle Baffle + Symmetrical Membrane Valve Smart Valve Positioner
Intelligent valve positioner, with built-in microprocessor and advanced control algorithm, has obvious advantages compared with mechanical positioner.
Product application field
TORLEO brand TOP-5879F1 series smart valve positioner are used in conjunction with pneumatic control valves, and are widely used in metallurgy, power generation, paper-making, environmental protection and other industries where process control is required.
Typical valve application
Double-acting ball valve, double-acting butterfly valve, V-shaped ball valve, yellow valve, damper valve
Technical features of the product
- Based on nozzle baffle + symmetrical membrane valve technology, it has strong resistance to moisture and oil pollution on site and high reliability;
- One-key auto-tuning, fool-like operation, easy for users to use and debug;
- Without external solenoid valve and power-off comparator, it can easily realize the function of fault blocking, and cooperate with the air lock valve to achieve three-break position retention;
- Built-in PST short-stroke test function to monitor the mechanical state of the shut-off valve online to ensure reliable action of the shut-off valve;
- On-line replacement of locator faults to ensure stable production process and equipment safety during maintenance;
- Modular structure design, convenient for users to choose feedback output and HART function;
- Built-in valve upper and lower limit contact output, convenient for on-site chain control;
- LCD screen and keyboard design, no need for a manual operator, easy debugging and tuning;
- Adopting advanced control algorithm, the control accuracy can reach within 0.3%.
