Water purifier valve

Water purifier valve

Water purifier valve is a control valve for controlling the operation of the water purifying system. The valve is provided to automatically stop the outflow of squeeze water while the faucet is in open condition. This saves additional water and also makes it possible to build up a relatively high pure-water pressure even when the inlet pressure is less than average.

Water purifier valve controls the operation of the system according to the water pressure present in the system's pure water delivery line. The control valve comprises four individual diaphragm valves linked together by hydaulic passages. The first of these diaphragm valves is a check valve inserted in the pure water delivery line that maintains pressure in the line between the check valve and the spigot when the spigot is closed. The second diaphragm valve is a pilot valve hydraulically linked to the pure water delivery. The third diaphragm valve is a squeeze water valve which opens in response to opening of the pilot valve and controls the flow of pressurized waste water from the reverse osmosis unit to a pure water tank in which the pure water is maintained in a bladder. Finally, the fourth diaphragm valve is an inlet water valve which controls the inflow of water from the main water line to the system.
