DESCRIPTION
Rain Bird manufactures only the highest quality valves. Use DV/DVF series valves in locations where the use of a separate pressure vacuum breaker (PVB) or a double-check valve is required by city codes to protect against back flow. Check your local city codes to determine what type of valves are required.
