The pilot operated regulator can adjust pressure remotely via a pneumatic command.
The two rolling diaphragms offer several advantages:
● increased stroke, which allows greater opening of the valve and hence increased flow rate;
● reduced dynamic and pickup friction, which results in increased response speed and high sensitivity;
● high precision in maintaining the set pressure, both with variable flow rates and different inlet pressures.
The design features the same construction characteristics as those used for a standard regulator, so the advantages are the same, namely: compensation of the regulated pressure varies with the upstream pressure; presence of a relieving valve and downstream pressure quick relieving.
