MAKE SEVERE SERVICE FLOW CONTROL EASY
English
D04 Differential pressure regulators are widely used for industrial applications.Such as city heating systems, large building heating networks and etc.The pressure differential regulators can matain a constant differential pressure between inlet and outlet pressure point.
The valve opens when the differential pressure rises.The typical application is the indirect connection of district heating systems(Installation of return flow pipe).

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.
