A direct acting reverse osmosis water purifier valve is disclosed. The purifier valve has a single diaphragm valve responsive to the pure water pressure to shut off the tap water inlet when the pure water pressure approaches the tap water line pressure, indicating that the pure water storage tank is full. This shut-off valve, in conjunction with the venting of the tap water line to drain within the system upon shut-off, results in a self actuating effect causing the shut-off valve to close in a positive manner once closing is initiated. Similarly, a direct acting pilot valve is used to control the squeeze water control valve to respond as desired to the pure water pressure to control the squeeze water for the purification and dispensing cycles. Functioning of the valve is very similar to that of the prior art though with a much simplified and more reliable structure.
