The non-return valve is designed for use in Seawater					When using multiple pumps in parallel, the
Reverse Osmosis (SWRO) membrane systems. In case the					non-return valve prevents the water from one
high-pressure pump stops momentarily, the volume of					pump to run into the parallel-coupled pumps at
water in the membrane vessel may work as an accumula-					start-up. The valve is prepared for easy installa-
tor and will send flow backwards.					tion on the high-pressure outlet of APP 53-86
					series 07 or lower.
					Use only Style 77DX coupling or equivalent.
