NISSAN TANAKA NT50B, NT50S Industrial Pressure Regulator
Manufacturer: Nissan Tanaka
Model: NT50B, NT50S
Widely compatible with various gas supply facilities and devices.
Integrated old model: Prince 35/Prince 100
Features
- Adopted a SUS (stainless steel) pressure gauge cover, reducing the occurrence of rust from the pressure gauge.
- Incorporated a filter, reducing internal leak troubles.
- The direction of gas inlet can be selected.
- Products with the same face-to-face dimension (157mm) as the Prince 35 series can also be manufactured.

＜Notes for Selection＞
- If you choose the ‘P: Plug’ option without a discharge valve, please install a separate valve with similar functions to the discharge valve (such as a safety valve).
- If you select ⑤ outlet pressure gauge scale “02 (0 to 0.25MPa)”, you can only select ② discharge valve “P: Plug”. In that case, ③ inlet pressure gauge scale can only be selected as “16 (0~1.6MPa)” or “25 (0~2.5MPa)”.
- There are restrictions on the outlet side usage pressure depending on the gas used. For acetylene, it’s up to 0.13MPa, and for LPG, it’s up to 0.19MPa.
- When using with carbon dioxide, please take measures such as installing a heater.
- The scale of the outlet pressure gauge cannot be set to a larger range than the scale of the inlet pressure gauge. (Example: Inlet pressure gauge: 1.6MPa, Outlet pressure gauge: 2.5MPa)
- It is possible to produce high-pressure gas equipment test products. Please contact us for more details.
