3/4-inch FPT Manual Anti-Siphon Sprinkler Valves | 51016

• For controlling the flow of water while also protecting a culinary water system
• Combines a manual irrigation valve with an atmospheric vacuum breaker
• Valve features flow control which can be operated by hand or with a sprinkler key
• Atmospheric vacuum breaker features a reliable poppet and seal design
  

NOTE: The valve is designed to operate continuously at up to 80 PSI for individual zone control. However, the vacuum breaker (anti-siphon) component should not be pressurized for more than 12 hours per day—extended pressure can cause the seal to stick to the seat, preventing the atmospheric vent from breaking the vacuum when needed. This valve is designed for scheduled zone control with regular on/off cycles, not as a continuously pressurized main line valve.
