Hayward Industrial Diaphragm Valves

 

Suitable for water, corrosive fluids and slurries
Precise flow control

These valves can be used for on/off and precise throttling. The valve controls flow by varying the space between a stationary weir and a moveable flexible diaphragm. By compressing the diaphragm against the weir, all flow is shut off. The only wetted components are the lower half of the valve body and the diaphragm. The diaphragm's stroke adjustment feature allows précising "tweaking" of diaphragm movement for very precise flow control. Hayward diaphragm valves are self-draining on one side so that little to no dead volume remains in the valve.

A large hand wheel makes it easy to operate the valve, and a beacon-type indicator provides highly visible position indication at the top of the valve's rising stem. Valves listed below are PVC with your choice of EPDM or FPM (comparable to VitonT) diaphragms. CPVC, Polypropylene and PVDF construction and PTFE diaphragms are available, as are flanged end connections in all sizes. Sizes 1/2" through 2" are true union with both socket and threaded connectors included.
