Stainless steel aseptic manual U-shaped diaphragm valve
The Stainless Steel Aseptic Manual U-Shaped Diaphragm Valve is a sanitary valve designed for manual flow control. Its U-shaped diaphragm ensures full drainage and leak-free operation, making it ideal for aseptic processes in pharmaceutical, biotech, and high-purity fluid systems
Working Principles
The Stainless Steel Aseptic Manual U-Shaped Diaphragm Valve operates by manually turning a handwheel or lever to press the U-shaped diaphragm onto the valve seat, controlling the flow of liquids or gases. The U-shaped design ensures complete drainage of the valve body, preventing fluid retention and contamination. When the diaphragm is lifted, the flow path opens, allowing media to pass through. The diaphragm forms a sterile barrier between the fluid and the mechanical components, ensuring aseptic operation. This design provides reliable, leak-free shutoff and smooth manual regulation, making it ideal for pharmaceutical, biotech, and other high-purity applications where hygiene is critical
