Asahi manual diaphragm valve type 72 DN200-250
Manual shut-off or control valve for corrosive, viscous, contaminated or abrasive media. Especially suitable in applications where the valve is frequently operated. The valve is sealed in both flow directions at low tightening torques. The valve is operated by handwheel (lockable as an option) with visual indication, providing a safe indication of the valve position. For diffusing liquids, a PVDF diffusion protection is recommended. This prevents corrosive gases from attacking the valve stem.
