Non-return & water supply valves

Non-return valves

There are several circumstances in the mixture transport process that require that the return of material must be avoided. This is the task for the non-return valve. They are commonly used on board dredgers and after booster stations. The occasionally necessary opening of a pump for inspection, repair or removal of obstructions must be done without risk of the mixture spilling through the open pump. The use of a non-return valve in such a situation avoids this risk and reduces maintenance and repair time. Non-return valves are fully self-operating so no manual or hydraulic operation is necessary.
