Manual Diaphragm Valve Description
Manual Diaphragm Valve is operated by turning the handwheel, which drives the valve stem up and down to control the opening and closing of the diaphragm. The high-quality diaphragm system features a smooth, crevice-free flow path with no dead zones, ensuring easy cleaning and compliance with sanitary standards. The valve installation length meets the ≤3D requirement, making it suitable for hygienic applications such as food, beverage, pharmaceutical, and biotechnology processes.
