Glass lined weir diaphragm valve`

The manual weir-type glass-lined diaphragm valve is a premier fluid control solution designed for highly corrosive, hazardous, or sensitive chemical media. Featuring a standard weir structure, the valve uses a resilient internal diaphragm to completely separate the flow channel from the upper bonnet and stem assembly. The valve body's wet parts are fully covered with a high-durability glass-enamel lining, offering a smooth, non-stick, and contamination-free surface that stands up to severe acids, alkaline solutions, and chemical solvents.
