Glass lined diaphragm valve

The manual glass-lined diaphragm valve is specifically engineered for regulating and isolating highly corrosive, hazardous, or high-purity fluids. Utilizing a classic weir-type design, the flexible elastomer diaphragm completely seals off the internal bonnet assembly from the media path. The valve body's interior is fully protected by a smooth, non-reactive glass-enamel layer, preventing metal contamination and providing outstanding resistance against acidic compounds, chemical solvents, and abrasive slurries.
