Anti-siphon valve with freeze protection
An anti-siphon system for use with an irrigation system, such as lawn sprinkling system is disclosed. The system includes a backflow prevention valve with a bonnet- and poppet valve system with a conical spring that biases a lower poppet valve head, and engages the valve body. The use of the conical spring simplifies the mechanism, while providing reliable backflow prevention.
