ITT Controls RMG 330 Owner's manual

Brand: ITT Controls

Model: RMG 330

Type: Owner's manual

ITT Controls RMG 330 is a direct-acting gas pressure regulator designed for commercial and industrial gas installations and local supply systems. It can be used for a variety of gases, including natural gas, propane, and butane. The RMG 330 has a wide inlet pressure range of up to 16 bar and can regulate outlet pressures from 20 mbar to 1000 mbar. It is also equipped with an integrated safety shut-off valve (SSV) that can be triggered manually or remotely.

The RMG 330 is a versatile and reliable gas pressure regulator that is suitable for a wide range of applications.
