Non-Return Valve.

The picture on the left shows the cheaper 1" F-F NRV c/w strainer basket already attached - A strainer basket is not supplied as standard with the more expensive 1" F-F NRV and has to be ordered separately.

Non-Return Valves are fitted in the end of the fuel line to prevent fuel running back out of the hose line. These are essential for use where the pump requires an initial prime to get it working and you wish to maintain the prime thereafter.

There is a separate strainer basket available for the 3/4" and 1" F-F NRVs - please add to cart separately if required.  These Strainer Baskets are Male threaded to fit into the inlet of the Female threaded NRVs.

All threads are BSP and the flow direction is either Female In and Female Out or Male In and Female Out,

Sizes available from 3/8" to 2" with Female to Female ports and 1/2" to 2" with Male to Female ports.

Tip: Do not fit a NRV where a piece of equipment in the line already has an integral NRV, such as a Tigerloop, because the pump will be struggling to overcome the resistance of two NRVs.

Tip: If you require a 1" female to female NRV with a filter basket already attached then we can supply this for less than buying a 1" NRV on its own (Note: The NRV sold on its own with a separate basket is of a stronger construction that the NRV sold complete with basket attached).
