Jones® J7000 Series Break Check Valve Brochure

Designed for ease of installation and superior infrastructure protection, the Jones J7000 Break Check provides “install and forget” passive protection. When struck by a vehicle, the J7000 closes automatically and slowly over an extended period, up to 15 seconds, minimizing water hammer, property damage and water loss.
