The pressure regulator independently sets the required pressure in the pipeline, and no complex electrical equipment is required for this. At the input and output, the pressure regulator must have either branches with a threaded, coupling or flange RD-110 with a flange connection, in addition to the two main branches, the pressure regulator, as a rule, has branches for a pressure gauge and a screw pressure regulator. The regulator allows you to protect equipment during a sudden change in pressure or water hammer.
