Pneumatic glass lined diaphragm valve

The pneumatic diaphragm glass-lined diaphragm valve is an advanced fluid control solution designed for automated regulation and isolation of aggressive, hazardous, or high-purity media. Equipped with a high-performance multi-spring pneumatic actuator, the valve ensures rapid and reliable automated switching or throttling. The internal wet parts feature a smooth, non-reactive glass-enamel lining combined with a flexible elastomer diaphragm, completely isolating the valve bonnet from corrosive chemicals, acids, and abrasive slurries while avoiding metal contamination.
