4-way automatic flushing valve for 1/4'' tubing

4-way valve for water tubing ∅ 1/4'' (6.35 mm) with quick-connect mounting for domestic reverse osmosis systems.
This 4-way valve acts as an automatic shut-off when the storage tank is full and the internal pressure rises; the valve automatically cuts the raw water supply to the membrane, preventing the system from running continuously. It operates mechanically by pressure difference, without electricity, and helps protect the membrane and reduce water consumption.
