ITO NBG Range AA/ AB Governor
Manufacturer: I.T.O Corporation
Model: NBG Range
AA Governor
Incorporated: Strainer
- The NBG-50-MA range is a direct-operated governor from Medium Pressure A to Medium Pressure A.
- The NBG-50MA with a higher outlet capability of 0.30~0.55 MPa is newly added to our product line. This product can correspond to the co-generation system incorporating a 2000~5000 kW gas engine, which are used in factories or large-scale commercial use, such as hospitals and hotels.

AB Governor
Incorporated: AR-OPSO*, Strainer. (*NBG-50H only)
- The NBG range is a direct-operated governor from Medium Pressure A to Medium Pressure B, which provides outstanding quick response and easy maintenance.
- The NBG-50 incorporates the ITO balancing piston system, which minimises any outlet pressure fluctuations caused by differing inlet pressures. This system allows the NBG range to give accurate and stable pressure control.
- Since this model has the simple structure of a direct-operated regulator, it gives quick responses and is easy to handle and maintain.
