Manufacturer: Nissan Tanaka
Model: S-TORR V 30

For inlet low-pressure, standard model: S-TORRⅤ30 / 30SH

Features

• The S-TORR regulator is a high-purity gas pressure regulator developed based on the highly trusted TORR regulator used in semiconductor process gas lines.
• By eliminating the screw structure of the gas contact part and applying standard electropolishing, it achieves very high moisture displacement characteristics and reduces particles.
• The body and fittings are connected by welding, and the external seal of the diaphragm part employs a metal seal structure. Due to its high external sealability, it can be used with confidence, especially with high-purity gases.
• It incorporates a filter in the flow path of the primary chamber, reducing internal leaks.
• Including helium leak tests, all products undergo thorough shipment inspections.
• The STⅤ30 series is a standard model for low-pressure primaries and is widely used in low-pressure piping, outlet panels, and cylinder cabinets of gases with low filling pressure.
• For corrosive gases, we offer the SH series using Ni-Cr-Mo alloy, a material with high corrosion resistance for the main metal parts in contact with the gas.

Designated Attention

※1 If you choose the 4-port specification, please select the symbol for the primary-side pressure gauge from the options below and replace it with the product name assembly “30X”

※2 In the case of not having a secondary pressure gauge, the symbols for each operating

※3 In the case of 2 ports, please select “X.” “X” refers to a product without a pressure gauge (unprocessed port). If you have only fittings without a pressure gauge and want to protect the fitting with a resin cap, select “F.” If you want to secure it with a metal plug, select “B.”
※4 In the case of other types of joints, different symbols are used.
※5 In the case of other shapes, different symbols will be used.
※6 We have selected the optimal resin for each type of gas used in the gas connection part (nozzle).
※7 This is an example of additional specifications. In the case of specifying interfacial dimensions or other special requirements, different symbols or numbers will be used. Please inquire for more details.

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