STAINLESS STEEL Aluminum Groove Type Demco Gearbox Butterfly Valve

The Demco gearbox butterfly valve, featuring a grooved design on stainless steel and aluminum alloy, opens and closes pipeline media by pneumatically or manually rotating the valve stem. The gearbox amplifies the operating torque, allowing the butterfly plate to easily open and close within the pipeline. When opening, the butterfly plate rotates away from the valve seat, allowing for smooth media flow; when closing, the butterfly plate presses against the valve seat, achieving a reliable seal and preventing media leakage. The butterfly plate can be designed eccentrically or standardly to reduce friction and wear, extending service life. The grooved valve body facilitates quick installation and disassembly, making it suitable for automated control and frequent opening/closing conditions in water, gas, steam, and chemical liquid pipelines.

• Pneumatic Actuation – Provides fast, automated operation for precise flow control, reducing manual intervention and improving process efficiency.
• Split Rotary Disc Design – Ensures smooth, stable flow modulation with minimal pressure drop and accurate control.
• Stainless Steel Construction – Durable and corrosion-resistant, suitable for hygienic and high-purity applications.
• Leak-Free Sealing – Precision-engineered seats ensure reliable shutoff and maintain sanitary integrity.
• Sanitary Surface Finish – Smooth, crevice-free interior surfaces support cleaning-in-place (CIP) and minimize contamination risks.
• Compact and Versatile – Space-saving design allows easy installation in pipelines and integration with automated systems

The Stainless Steel Sanitary Pneumatic Split Rotary Butterfly Valve is widely used in industries requiring precise, automated, and hygienic flow control. Typical applications include beverage production for controlled liquid distribution, pharmaceutical manufacturing for sterile fluid handling, biotechnology for media transfer, and food processing where contamination-free, accurate flow regulation is essential
