The ASV2000N is development and manufactured in the US by US company HYDRONAMIC ENGINEERING INC. The ASV2000N is a compact valve with four fully integrated 1/4" tubing connections. This valve is designed for a reverse osmosis system with a capacity of up to 50gpd product water(50gpd membrane). The valve shuts off when the tank pressure reaches 60% of the line or feed water pressure. The ASV2000N has earned the Gold Seal for material safety and structural integrity from the Water Quality Association.

Below is an installation schematic showing the correct installation position in a Reverse Osmosis system.

The diaphragm which shuts off the flow of water in the shutoff valve is located in the large band around the middle of the shutoff valve. The water actually goes into the valve and then comes out of the connection beside it (not across from it). This is the same for the low pressure side (after the membrane).
