Repair of flush valve components, rather than replacement of the entire unit, saves money and resources. Zurn’s plunger assembly (Part no. PH6000-HYM) is designed for AquaVantage® and AquaFlush® hydraulic series flush valves. Zurn hydraulic flush valves have a non-hold-open type hydraulic push-button actuator that can be located up to 36 inches away from the valve. They feature a quiet GO BLUE® diaphragm with a clog-resistant bypass and chloramine-resistant seals 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.
