Spill Resistant Pressure Vacuum Breaker Assembly
Page 1 of 2
Application
Ideal for use where Lead-Free* valves are required. De-
signed for installation on indoor and outdoor point of use
applications to protect against backsiphonage of contami-
nated water into the water supply. During start-up and
operation a separate diaphragm seals the air inlet from the
water supply preventing spillage. The assembly is designed
for use under constant pressure and provides protection
where a potential health hazard exists.
