TOP-5879F1-C41 Flameproof Type/Dustproof (Intelligent Valve Positioner) - Product

The TOP-5879F1-C41 series intelligent valve positioner adopts nozzle baffle technology and is used in conjunction with pneumatic control valves (such as diaphragm control valves, ball valves, butterfly valves, etc.). It is widely used in the precise control of flow and other aspects in the production process of industries such as petroleum, chemical, metallurgy, electric, power, and paper-making.

Product features:

- IP adopts nozzle baffle + membrane valve structure, static air consumption is less than 25L/h, and has strong ability to resist dust, moisture and oil on site

- In addition to conventional reset control, users can choose to only equip the air lock valve to easily achieve power off, signal off, and air off three-break position control

- The product has built-in buttons and a large-size LCD screen for users to operate on site

- HART7 version communication and 4~20mA valve position feedback output, users can choose to configure

- The valve can be set to linear, fast opening, equal percentage and user-defined flow characteristics at will, which is convenient for valve control

- One-button self-tuning operation, fool-style operation

- Using advanced composite control algorithm, it can achieve 1-0.3% control accuracy

- Simple menu operation setting to solve the problem of on-site application of intelligent positioners and maintenance and exchange in online production

- Built-in PST partial stroke test to facilitate SIS control of shut-off valves
