Our auto shut off valves are used with reverse osmosis water systems and they're incredibly simple but can be really effective. These valves automatically turns off the water production when the unit reaches a full tank. These parts monitor the pressure inside the tank and when the tank is already full, it shuts off the water that goes into the reverse osmosis membrane.
The auto shut off valve uses the back pressure amount created by the float valve. That pressure is used to shut off water production. If your reverse osmosis system has this feature it's a great option because it automatically works and doesn't rely on electricity since it's pressure based.
