Manufacturer: Nissan Tanaka
Model: TORR-80

Low-pressure, standard model for the primary side low-pressure use: TORR-30

Features

• The TORR series, synonymous with “semiconductor gas pressure regulators” due to its long track record, has earned high reliability.
• Technicians perform assembly in a Class 1000 cleanroom to a 0.3μm standard.
• A built-in filter in the primary chamber’s flow path reduces internal leaks.
• We conduct a helium leak test on every unit as part of our comprehensive shipping inspection.
• We can also produce specifications for electrolytic polishing (contact gas metal part surface roughness Ra0.25μm).
• You can use the TORR-80 series as a medium flow model for primary low-pressure applications, suitable for primary pressure reduction of liquefied gases or in piping that requires flow rate control.

Designated Attention

※1 If a 4-port specification is selected, please choose the symbol for the primary side pressure gauge from below and replace it with the number 30 in the product name assembly.

Primary side pressure gauge symbol	Maximum operating pressure
03	-0.1～0.3MPa（0.2MPa)
06	-0.1～0.6MPa（0.4MPa)
10	-0.1～1.0MPa（0.6MPa)
15	-0.1～1.5MPa（1.0MPa)
30	-0.1～3.0MPa（2.0MPa)

※2 If there is no secondary pressure gauge, the symbols for each operating pressure are as follows:

Operating Pressure	Symbol
～0.2MPa	03
～0.4MPa	06
～0.6MPa	10

※3 In the case of other shapes, different symbols are used.
※4 When using slant connectors, the structure is basically a welded connection for structure ②. For other types of connectors, structure ② is essentially a threaded connection.
※5 Only joint types S (SwageLock) and F (FineLock) are available for selection.

⚠️Warning: For correct usage, please make sure to read the ‘Instruction Manual’ carefully before use.
