Diaphragm valve V402

with handwheelpneumaticfor control

Ideally suited to be installed as a tight shut-off or control valve in lines particularly containing abrasive or corrosive chemicals,slurries,powders,gases and high viscosity liquids with suspended solids which tend to clog conventional valves.Face to Face dimensions are according to BS 5156(short-pattern) or DN3202-F1(long-pattern). Available as unlined or lined with flanged or threaded end connections. Weir in the flow passage is designed to reduce the flexing of the diaphragm to a minimum,while providing a smooth and streamlined flow passage. Permits the use of a great variety of construction materials such as PTFE for the diaphragm. Unlike "Weir Type" diaphragm valves , valves with "Straight Through" flow passage require a more flexible diaphragm,therefore the construction material for diaphragms is restricted to elastomers.    Optional Accessories/Configurations   • Threaded End Connections • Pneumatic Actuator Operated • Lockable Handwheel
