TruDesign® Non-Return Valves are designed for marine, farming, horticulture and mining industries. Made from UV stabilised glass reinforced Nylon, these composite material fittings are designed for the harsh marine and agricultural environments. They can be used in line to prevent water backflow or siphoning and have a very low cracking pressure. Threaded non return valves are used for outlets only to avoid backflow.
