The non-return valve is designed for use in Seawater
Reverse Osmosis (SWRO) membrane systems. In case
the high-pressure pump stops momentarily, the
volume of water in the membrane vessel may work
as an accumulator and will send ow backwards.

When using multiple pumps in parallel, the
non-return valve prevents the water from one
pump to run into the parallel-coupled pumps at
start-up. The valve is prepared for easy installa­tion on the high-pressure outlet of APP 53-92
series 08 or higher.

Use only Style 77DX coupling or equivalent.
