Automatic Shut Off Valve for Reverse Osmosis Water Purification Systems

The device features a 4-way valve designed to regulate the inlet flow of reverse osmosis (RO) membrane based on the RO tank's water pressure. It has quick-connect ports that are essential components for most under-sink reverse osmosis (RO) water purification systems. The device automatically cuts off the membrane inlet water once the tank pressure reaches approximately 60% of the incoming line pressure, saving water and preventing leaks.

This product is easy to install with its quick-connect ports that fit standard OD water filter tubing. It is durable and reliable, with an operating pressure range of 30-100 PSI and a maximum temperature of 120 °F (50 °C). The device is also accurate and consistent, with a shut-off pressure of 40 PSI at 60 PSI feed water pressure (Accuracy +/- 20%).

In summary, this device is a crucial component for under-sink reverse osmosis (RO) water purification systems. It automatically regulates the inlet flow of the RO membrane based on the tank's water pressure, ensuring efficient water usage and preventing leaks. Its quick-connect ports and durable construction make it easy to install and reliable in operation, with consistent performance even in varying water pressure and temperature conditions.
