Provision introduced in the pilot valve allowing reduction in the time of opening and closing of the valve or pressure differential.As well as allowing an adjustment made from the body of the pressure regulator (16) and the variation of pressure necessary for the opening of the valve, for various systems.With the use of only one spring (15), (without the need of replacement parts).As well as avoiding subsequent adjustments and benchmarking in the field (7) and the body regulating pressure differential (10), built in parts only, monobloc,Forming a perfect guide for regulating stem (13) of the sphere (7),Which is aligned with the body unit (10) without blocking and allowing the pilot valve to fulfill its function effectively to control the opening or closing of a second valve or Vu00e1lvula of relief, so that the air reservoir, a compressor is maintained at constant pressure for the system in use.
