PRODUCT OVERVIEW

Electric wafer type fluorine lined butterfly valve is a common anti-corrosion valve in chemical transmission pipeline. The flow channel, butterfly plate and valve stem of wafer type fluorine lined butterfly valve are fully lined with Teflon, which has good corrosion resistance. Electric wafer fluorine lined butterfly valve can be applied to pipelines with corrosive media such as sulfuric acid, alkali, hydrochloric acid, oxidant and reductant, and can replace gate valve, stop valve and other types of cut-off and regulating valves. Driven by (220V, 380V) power supply voltage and receiving (4 ~ 20mA) industrial signal output by automatic instrument, the valve stem is driven to drive the rotation of butterfly plate to complete the switching and adjustment of butterfly valve.


PRODUCT FEATURES

1. Novel design, light structure, quick opening and closing, small operating torque, and can be installed at any position. The seals can be replaced, and the sealing performance is reliable. It has the characteristics of two-way sealing without leakage, aging and corrosion resistance of sealing materials, long service life and so on.

2. The electrical installation features can be intelligent, adjustable and switch type. It adopts single-phase power supply with simple wiring, double limit, overheating protection and overload protection. The full travel time is 15 seconds, 30 seconds, 45 seconds and 60 seconds, and has manual function.

3. The built-in module adopts intelligent control software to directly receive the output signals of industrial instruments (4-20mA DC / 1-5vdc) to realize the intelligent control and adjustment of valve opening.
