JONENG
Stainless steel gearbox indicator lug SS316L butterfly valves are available in manual, electric, or pneumatic types, sizes DN50–DN600, lug or wafer style, 316L stainless steel body, reliable sealing, corrosion-resistant, visual position indicator, durable, and suitable for industrial flow control.
The butterfly disk is installed in the diameter direction of the pipeline. When the butterfly valve in the pipeline, the disk rotates around the axis line, and the rotation angle range is between 0-90 degree. When the valve does not rotate at 0 degree, the valve disk is closed. When the valve rotates to 90 degree, the valve disk is opened absolutely.

Constructed from 316L stainless steel, providing excellent corrosion resistance, mechanical strength, and long-term durability for industrial and chemical applications.
Lug-type body allows secure flange installation, enabling easy maintenance and partial pipeline disassembly without affecting the entire system.
Gearbox operation amplifies manual torque, making it easier to operate large-diameter valves with minimal effort.
Visual position indicator provides clear feedback on valve status, helping operators quickly confirm open or closed positions.
The disc and seat design ensures reliable sealing, low leakage, and stable flow control under varying pressure and temperature conditions.
Sanitary Butterfly valve widely use in low and medium viscosity liquid for food and beverage, beer, dairy, pharmaceutical etc with high precision and purity requirements industries.
Working Principles
The butterfly disk is installed in the diameter direction of the pipeline. When the butterfly valve in the pipeline, the disk rotates around the axis line, and the rotation angle range is between 0-90 degree. When the valve does not rotate at 0 degree, the valve disk is closed. When the valve rotates to 90 degree, the valve disk is opened absolutely.
