The RB 4700 Series is designed to provide extremely accurate gas regulation over a wide range of flows and outlet pressures. Typical applications include large commercial and industrial installations, and district stations. The RB 4700 features a compact, multi-range pilot system that is easy to use, including strainer and feeder. The RB 4600 version can perform all the functions of conventional monitor and active regulators, integrated in a single device.
The RB 4700 is optionally fitted with a built-in safety shut-off valve for over-pressure and under-pressure protection: SSV 8500 offers a cost-effective solution for moderate inlet pressure, while SSV 8600 is a versatile safety valve with lever reset; both types are equipped with a mistake-proof SSV by-pass. The RB 4700 also incorporates a robust and efficient noise abatement cage (optional).
