Features:

• Utilizes a two-stage pressure reduction structure, allowing for the maintenance of high-precision output pressure unaffected by changes in cylinder pressure.
• Ideal for situations requiring a constant pressure supply over an extended period.
• Suitable for fine pressure and flow rate adjustments.
• Equipped with a Teflon-coated diaphragm, making it suitable for use with H2 and He gases.
• Includes an integrated filter to reduce internal leakage issues.
• Applicable for various purposes by utilizing a free-entry specification for both input and output.
• All items are available as standard stock.

※The set pressure and the maximum allowable pressure may differ depending on the gas type.
※The flow characteristics do not apply to water, oil, or other liquids.

• It is a flow meter compatible with JETV.
• Connection with JETV is simple because it uses an M16×1.5 connection (the same as a hose mouth).
• It is a standard stock item.

Other fittings

In addition to the standard fittings, custom-made fittings for JETV are also available.

⚠️Warning  Before using, be sure to read the instruction manual carefully to avoid incorrect use that may cause accidents or damage.
