The STAINLESS STEEL Butterfly Valve is a sanitary electric-actuated valve that prevents fluid mixing, ideal for dairy and food-grade pipelines with hygienic stainless steel construction and reliable flow control.
The stainless steel electric wafer-type anti-mixing milk butterfly valve operates by using an electric actuator to drive the valve shaft and control the butterfly disc position. When a control signal is received, the actuator converts electrical energy into rotary motion, opening or closing the disc to regulate or isolate flow. The anti-mixing design incorporates a special sealing and chamber structure that prevents different fluids from mixing, even during valve switching or cleaning cycles. This is especially important in milk and dairy processing, where product purity and hygiene are critical. The wafer-type connection allows the valve to be clamped securely between pipe flanges, ensuring compact installation and easy maintenance. Smooth internal surfaces and stainless steel materials support effective cleaning, reliable operation, and compliance with sanitary processing requirements.
