The air blow check valve is designed to pressurize lines with air to clean out product or cleaning solutions. It is fail-safe because the simple air-to-open, spring-to-close mechanism prevents backflow. Can be used with a ball check valve. The valves are available with three different end configurations to allow quick assembly and disassembly when replacing filter media, cleaning or inspecting. Conforms to 3A accepted practice 604-05 for supplying air under pressure in contact with milk products and product contact surfaces with optional filter disc.

Features
  • EPDM seat and gasket
  • Conforms to 3A practice 604-05
