FUJIKURA FMNV1 Precision Needle Valve without Multi Dial

• Precise flow adjustment: The non-rotating needle structure enables about 13 rotations for fine and smooth flow control.
• Without multi dial: The no-multi-dial design is suitable for applications where flow is confirmed by equipment conditions, tools, or external monitoring.
• Wide needle lineup: Needle numbers N1 to N10 are available, covering maximum Cv values from 0.00021 to 0.25.
• Angle and straight types: Angle and straight body types are available for different piping directions and installation spaces.
• Gas and liquid applications: The valve supports gas and liquid that do not corrode wetted parts, including machine tools, medical equipment, analyzers, water-treatment equipment, and gas generators.

Q1: What is the FUJIKURA FMNV1 Series?
A: The FMNV1 Series is a precision needle valve without a multi dial, used for fine flow adjustment in gas or liquid piping.

Q2: What is the difference between FMNV1 and FMNV2?
A: FMNV1 is the type without a multi dial, while FMNV2 includes a multi dial for applications requiring position reading, repeatable settings, or visual adjustment reference.

Q3: Why is FMNV1 suitable for precise flow control?
A: The non-rotating needle structure provides about 13 rotations, allowing smooth flow changes for small-flow and fine-adjustment applications.

Q4: What fluids can the FMNV1 Series handle?
A: It supports gas and liquid that do not corrode wetted parts. Special liquids, solvents, or corrosive fluids require material compatibility confirmation.

Q5: What body materials are available?
A: Brass and stainless steel types are available. The brass type is nickel plated, and the stainless type uses SUS316.

Q6: What connection types are available?
A: The standard pipe port is Rc1/4. Φ1/8, Φ1/4, Φ4mm, and Φ6mm tube joint options are also available, but tube joint specifications correspond only to stainless steel models.

Q7: What needle numbers are available?
A: Needle numbers N1 to N10 are available, with maximum Cv values from 0.00021 to 0.25.

Q8: What is the maximum working pressure?
A: The maximum working pressure is 1.0MPa, and the pressure resistance is 1.5MPa.

Q9: Is no oil treatment available?
A: Yes. Add N0 at the end of the model number for no oil treatment, suitable for equipment conditions sensitive to oil content.

Q10: What applications is the FMNV1 Series suitable for?
A: It is suitable for machine tools, industrial furnaces, medical equipment, analyzers, fuel cells, batteries, water-treatment equipment, gas generators, compressors, and other precise flow-adjustment lines.
