I.T.O Corporation
ITO REGIT-AB Range AB Governor Unit
Manufacturer: I.T.O Corporation
Model: REGIT-AB Range
Incorporated: AR-OPSO, Relief, Strainer.
Japan Gas Association Technical Prize
- The REGIT-AB range is a unit of pressure reducing governors from Medium Pressure A to Medium Pressure B and multiple safety devices into one same compact body regardless of the single (REGIT-AB-S) or double unit (REGIT-AB-W).
- Widely used as an Exclusive Governor or small-scale District Governor.
- Only direct-operated governors used, which provides outstanding quick response and easy maintenance.
- The REGIT-AB-W has a double line structure, which allows its use without suspending gas supply during maintenance and so does not require installation of temporary governors.

Auto-Reset OPSO (AR-OPSO)
The ITO “AR-OPSO”, an inner auto-reset type over pressure shut-off valve incorporated additionally, works to avoid outlet pressure rises if any foreign object is caught between the main valve disc and the main orifice, inner sealing failed.
Safety Relief Valve
A valve that opens and releases overpressure into the air to prevent abnormal pressure increases.
| Mounting pipework and storage box are available as separate accessories. |
