Spill Resistant Pressure Vacuum Breaker

The 460XL Spill Resistant Pressure Vacuum Breaker is utilized in high health hazard, indoor and outdoor point of use applications for protection against backsiphonage of contaminated water into the water supply. As opposed to standard pressure vacuum breakers, the 460XL reduces or even eliminates spillage during start-up and operation, as the separate diaphragm effectively seals the air inlet from the water supply. Designed for use under constant pressure, its modular design reduces repair time and labor costs. Features include a cast bronze valve body, FDA approved silicone elastomers and polypropylene polymers, and quality 300 series stainless steel springs.
