STAINLESS STEEL DN200 Electric Actuator Bolei Rotary Butterfly Valve

The stainless steel DN200 electric actuator Bolei rotary butterfly valve operates by converting electrical energy into mechanical rotary motion to control fluid flow. When an electrical signal is sent to the actuator, the internal motor drives a gear mechanism that rotates the valve shaft. This rotation turns the butterfly disc inside the valve body between fully open, partially open, and fully closed positions. As the disc aligns parallel to the flow direction, resistance is minimized and fluid passes through smoothly; when rotated perpendicular, the flow is shut off. Position feedback devices inside the actuator ensure accurate angle control and repeatable operation. This working principle allows precise flow regulation, remote control, and reliable automation in industrial piping systems.

Valve parts

• Constructed from high-grade stainless steel, providing excellent corrosion resistance, hygiene compliance, and durability for food, beverage, and pharmaceutical applications.
• Diaphragm-actuated design ensures precise valve control with minimal leakage, enabling smooth and reliable opening and closing.
• Solenoid operation allows fast response and integration with automated systems for remote or timed control.
• Sanitary design with smooth internal surfaces prevents contamination and ensures easy cleaning and maintenance.
• Compact and lightweight structure simplifies installation in pipelines with limited space while maintaining stable and efficient operation

The Hastelloy Sanitary Light Rotary Powder DIN Butterfly Valve is commonly used in industries handling corrosive or high-purity powders. Typical applications include pharmaceutical manufacturing for powder dosing, chemical processing for corrosive materials, and food or nutritional supplement production where sanitary, precise, and contamination-free powder flow control is essential.
