GAS PRESSURE REGULATOR RDM 50-150-К04 Russian National product classification code 37 4250 SPECIFICATION No. 3742-017-12317765-97

DESCRIPTION

Gas pressure regulator RDM 50/150-К04 is used in gas supply systems and is designed to reduce high gas pressure to a set average value, as well as for automatic maintenance of output pressure within set parameters irrespective of input pressure differential and consumption, for stopping automatic gas supply when input pressure rises to an emergency level over acceptable set paraments.

Use permit No. РРС 00-24987. Compliance certificate No. РОСС RU.МЕ55.В01646.
