D02 Pressure relief regulators or we can call it excess pressure regulators provide a desired and constant upstream pressure.The upstream pressure which the regulators matain we call it setting pressure.For the pressure relief regulators the valve opens when the upstream pressure rises.Pressure relief regulators are necessary for the pipeline system to get free of overpressure damages.

D13 Pilot operated regulators are typically used for these applications which need large flowrate or precise pressure control is required.Pilot operated pressure relief regulators are consisted of main valve and pilot valve,when the pilot valve detected the upstream pressure rises,it will respond quickly and accurately to open the pilot valve,after the pilot valve opening,the main valve will also been opened by the upstream pressure.Through above two paths,the regulator achieve the purpose of pressure relief.
