Stainless Steel Sanitary Weld Pneumatic Actuated Switch Butterfly Valve
The Stainless Steel Sanitary Weld Pneumatic Actuated Switch Butterfly Valve is an automated valve designed for rapid flow control. Its welded stainless steel body ensures durability and hygiene, while the pneumatic actuator allows precise, leak-free switching suitable for sanitary and industrial fluid systems
Working Principles
The Stainless Steel Sanitary Weld Pneumatic Actuated Switch Butterfly Valve operates using a pneumatic actuator to rotate a disc mounted on a central shaft within the welded valve body. When compressed air is supplied, the actuator turns the disc 90 degrees, aligning it with the pipeline to allow flow or positioning it perpendicular to stop flow. The disc seals against elastomeric or metal seats, ensuring leak-free shutoff. Its welded construction provides a smooth, sanitary flow path with minimal dead space, reducing contamination risk. This design allows rapid, precise switching, making it ideal for sanitary, food, pharmaceutical, and biotech applications requiring automated flow control
