Backwash Valves

Yardney Backwash Valves are manufactured in-house. All three Yardney backwash valve models (1-1/2", 342 & 454) are manufactured from cast iron and CNC machined for proper and effective sealing of all wetted surfaces in order to achieve the lowest documented pressure drop in the industry. The Yardney Backwash Valve is designed as standard equipment to be 100% field serviceable with basic hand tools and includes a grease fitting for valve shaft lubrication and replaceable brass bushing and all sealing and gasketed surfaces.
