千代田精機 List of Products and Services

Our company offers a wide range of minister-certified products, including "pressure regulators and valves." We have a lineup that includes single-cylinder "pressure regulators" suitable for airtightness and pressure testing, as well as "valves (spherical valves)" with a special spindle structure that separates the valve body and valve rod. High-pressure gas manufacturing facilities, storage facilities, sales facilities, and specific high-pressure gas consumption facilities require notification to the relevant prefectures and permission from the governor, and they must undergo completion inspections and safety inspections. In this regard, certified products simplify the completion inspection process as "pressure tests" and other requirements can be omitted. 【Benefits of Using Certified Products】 ■ Pressure tests and other requirements can be omitted ■ Completion inspections become easier *For more details, please refer to the PDF materials or feel free to contact us.

We handle the dry safety device for hydrogen, "Save Point-L type." The "LH-15 type" is a dry safety device that can be used in hydrogen gas supply equipment for industries such as cutting and welding using hydrogen gas, glass and ceramics, metal reduction and metallurgy, and petrochemical industries. In addition to the newly developed (PAT.) pressure-sensing cutoff mechanism, it incorporates a thermal-sensing cutoff mechanism, creating a dual safety mechanism that responds to backfire at the unique low pressure of hydrogen, cutting off gas supply and preventing backfire propagation. 【Features】 ■ The main body and other materials are made of brass. ■ Pressure-sensing cutoff mechanism: Cuts off the gas flow path when backfire occurs. ■ Thermal-sensing cutoff mechanism: Cuts off gas supply when gas continues to burn inside the safety device. *For more details, please refer to the PDF document or feel free to contact us.

The "SRO-A/SRA-A" is a stout pressure regulator equipped with a dry safety device. It includes models for oxygen gas, the "SRO-A," as well as for acetylene gas, the "SRA-A." According to the High-Pressure Gas Safety Act, the installation of a backfire prevention device (dry safety device) is mandatory for acetylene consumption equipment used for welding or cutting. We also recommend pressure regulators with built-in dry safety devices for oxygen. 【Features】 ■ For acetylene and oxygen ■ Built-in dry safety device ■ With gauge protector ■ Compliant with the Ministry of Health, Labour and Welfare's technical guidelines for dry safety devices (SRA-A model) *For more details, please refer to the PDF document or feel free to contact us.

The "CVR type" is a carbon dioxide vaporizer that stably supplies carbon dioxide gas vaporized through warm water heated by an electric heater. For cylinder and LGC applications, the adoption of the vaporizer allows for the minimum necessary number of carbon dioxide containers, requiring less installation space. It comes standard with a water level low alarm device, which, when the water level of the warm water drops, triggers an alarm and cuts off the heater circuit to prevent the heater from running dry. 【Features】 ■ Uses an electronic temperature control device ■ Comes standard with a water level low alarm device ■ Uses a dedicated heater ■ Uses certified parts for high-pressure components (excluding CVR-25 type) *For more details, please refer to the PDF materials or feel free to contact us.
