Marketing InformationThe Apollo® model PVB4A pressure vacuum breakers prevent contamination of the potable water supply due to back-siphonage. An integral freeze protection relief valve serves to reduce the possibility of damage due to intermittent freezing conditions. The modular check valve cartridge provides a captured spring, a replaceable seat and a reversible silicone seat disc. This made in America assembly features Apollo® ball valves with stainless steel handles and nuts as standard and carries the five years Apollo® factory warranty.
