584 Series Flex-Check Valve

[584 Series]

Certified by the Water Quality Association to be in compliance with NSF/ANSI 61 Drinking Water Components Health Effects Requirements.

The Cla-Val Model 584 Series Flex-Check Valve is designed for long service life and maintenance free check valve operation compared to traditional swing check valves.  e During system flowing conditions the disc flexes up to the open position allowing unrestricted flow through the valve.  When system reverse flow conditions occur the disc flexes down to the closed position for drop-tight seal preventing reverse flow. It has a full-flow area body with integral seat at 45° angle to reduce head loss.  This minimizes disc travel to 35° degrees for improved no-slam check action and for reliable vertical up flow operation even on slurry applications.  The body and cover are fusion bonded NSF-61 epoxy coated for long service life on potable and non-potable systems.
