FILTER 4-WAY VALVE (AUTO SHUT-OFF) QUICK FIT 6MM

The 4-way shut-off valves are used on under-the-counter Reverse Osmosis (RO) and Nano Filtration water filtration systems. The 4-way shut-off is responsible for automatically shutting the supply water to the RO system off and on. The 4-way shut-off valve will turn off the water supply (which also stops the drain water), once the storage tank has been filled and the tap is closed. The 4-way shut-off valve is also responsible for turning the water supply back on, this will happen once enough the water level in the tank drops to below a certain level.
