The ASV-4000QK Automatic Shutoff Valve is one of the essential parts of any Reverse Osmosis system to prevent unnecessary waste water drainage. This shut- off valve is activated when the tank pressure reaches a certain percentage of incoming feed water pressure. The valve automatically shuts off incoming water to RO (reverse osmosis) system, when the tank pressure reaches approximately 60% of the incoming line pressure.
