Backwash Valves

Field Serviceable

Yardney Water Filtration Systems utilize backwash valves patented and manufactured in-house by Yardney. All three Yardney backwash valve models (1.5″, 342, 454) are manufactured from cast iron and CNC machined to achieve the lowest pressure drop in the industry. The Yardney Backwash Valve is the only valve in the industry designed as standard equipment to be 100% field serviceable with basic hand tools and includes a grease fitting for valve shaft lubrication.
