Description
The RB 4700 and RB 4700 D is a pilot-operated regulator with an integrated optional safety shut-off
device The balanced compensation system ensures constant outlet pressure when the upstream pres-
sure varies This regulator has a very high operating performance
Applications
It is designed for use in industrial and distribution applications: such as gas supply networks, district sta-
tions, heating plants and industries
It can also be used for all installations with continuous consumption and rapid variations of flow-rate
The accurate pressure control and fast response of the regulator are ensured by the perfect operating
performance of the pilot
