During normal flow conditions, the check valve remains open and the float seals on the cap assembly. As the line pressure falls to 1 psi, the spring loaded atmospheric vent valve opens, breaking the vacuum and thereby preventing back-siphonage. In the event of exposure to freezing temperatures, a spring loaded relief valve in the cap assembly protects the PVB body and internal components from damage. As the ambient temperature increases above freezing, the relief valve automatically reseats. During normal conditions, the relief valve will not discharge.
The Series 4V-500 is approved under ASSE 1020, CSA B64.1.2 and USC's FCCC&HR. Contact local water authorities for installation/service requirements.
