Repair of flush valve components, rather than replacement of the entire unit, saves money and resources. Lasting up to 10x longer than standard batteries, these lithium-ion batteries (Part no. PTR6200-BAT-LITH) work with EcoVantage® ZTR battery sensor flush valves, reducing maintenance costs and application downtime. EcoVantage® ZTR flush valves feature a piston-type design with clog-resistant components and a chemical-resistant GO BLUE® internal seal for an extended lifespan and lower maintenance costs. When you need a replacement part for repair or maintenance of a flush valve, trust Zurn for genuine, reliable parts.
