Product Details

• 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
• 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
• CPVC, polypropylene and PVDF construction and PTFE diaphragms are available, as are flanged end connections in all sizes
