View Our Range Of Non Return Valves

Darwen Diesels stock a range of Non return or one way valves varying from 6mm – 13mm. One way valves can be used for a multitude of problems, mainly where the fuel has drained back to the fuel tank due to the system drawing in air overnight. This has been a problem for many years. Come the morning and the engine is turning over….. and over…… on the ignition key. We also do NON RETURN VALVES built into a filter, please check out our filter section for more information
