An automatic flow regulator valve designed to regulate water pressure from a liquid source outlet in the event of pressure surges and/or fluctuations. In an “open” position, the predetermined water flow pressures are not sufficient to overcome a spring force of a spring. Therefore, a sealing plate is maintained separated from a step by the spring force, thus allowing water to flow around the outmost perimeter edge of sealing plate. In operation under water flow pressure surges and/or fluctuations, the automatic flow regulator valve is “closed”. In the “closed” position, the water flow pressure surges and/or fluctuation pressures are sufficient to overcome the spring force of spring. Therefore, the sealing plate is biased against the step and the water does not flow around the outmost perimeter edge of sealing plate since sealing plate is biased against the step.
