Regulator is designed for reduction of high or medium pressure, automatic keeping of output pressure on preset level, automatic gas feed cut under emergency increase and decrease of output pressure beyond allowable preset values.
Is installed in gas control points and gas control plants of the gas-supply system of the cities and other settlements. Is manufactured in variations: RDG-50-N, -80-N (for low pressure), and RDG-50-V, -80-V (for high pressure).
