Description
The RB 4700 and RB 4700 D is a pilot-operated regulator with an integrated optional safety shut-off device. The bal-
anced 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.
