Sanitary three-way LL flow regulating control valves are designed to provide precise flow regulation in hygienic processing systems, allowing operators to accurately control the flow rate of liquids or gases in sanitary pipelines.
Manufactured from high-quality stainless steel (SS304 or SS316L), the valve offers excellent corrosion resistance, hygienic construction, and reliable sealing performance. Its advanced pneumatic and electric control system supports 4–20 mA signal integration, enabling precise automation and stable process control.
These valves are widely used in food processing, beverage production, pharmaceutical manufacturing, biotechnology processing, and water treatment systems, where accurate flow control and hygienic operation are essential for maintaining product quality and system efficiency.
