An automatic flow regulator valve (10) 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 ( 130). Therefore, a sealing plate (102) is maintained separated from a step (36) by the spring force, thus allowing water to flow around the outermost perimeter edge of sealing plate (102). In operation under water flow pressure surges and/or fluctuations, the automatic flow regulator valve (10) is "closed". In the "closed" position, the water flow pressure surges and/or fluctuation pressures are sufficient to overcome the force of spring (130). Therefore, the sealing plate (102) is biased against the step (36) and the water does not flow around the outermost perimeter edge of sealing plate (102). Instead, water only flows through hole (104).
