FUJIKURA FMNV2 Precision Needle Valve with Multi Dial

• Multi-dial flow adjustment: The multi-dial display helps confirm rotation count and adjustment position for easier flow setting.
• Precise flow adjustment: The non-rotating needle structure enables about 13 rotations for fine gas and liquid flow control.
• One-touch dial locking: The multi dial can be locked by one touch to help maintain the set position and reduce unintended adjustment.
• Wide needle lineup: Needle numbers N1 to N10 are available, covering maximum Cv values from 0.00021 to 0.25.
• Panel mount support: The standard specification supports panel mounting, while option code F adds a lock ring for piping use.

Q1: What is the FUJIKURA FMNV2 Series?
A: The FMNV2 Series is a precision needle valve with a multi dial, used for fine flow control, flow adjustment, and repeatable flow setting in gas or liquid piping.

Q2: What is the difference between FMNV2 and FMNV1?
A: FMNV1 is the type without a multi dial. FMNV2 includes a multi dial that shows rotation count and adjustment position, making it better for repeatable settings or recorded flow positions.

Q3: Why is FMNV2 suitable for precise flow control?
A: The non-rotating needle structure provides about 13 rotations, and the multi-dial display makes fine adjustment easier to confirm and repeat.

Q4: What does the multi dial do?
A: The multi dial displays the rotation count, helping users record the adjustment position and repeat the same or similar flow condition later.

Q5: Can the FMNV2 multi dial be locked?
A: Yes. The multi dial can be locked by one touch to help maintain the set position and reduce unintended adjustment.

Q6: What fluids can the FMNV2 Series handle?
A: It supports gas and liquid that do not corrode wetted parts. Special liquids, solvents, or corrosive fluids require material compatibility confirmation.

Q7: 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.

Q8: What needle numbers are available?
A: Needle numbers N1 to N10 are available, with maximum Cv values from 0.00021 to 0.25.

Q9: What is the standard mounting method?
A: The standard specification is for panel mounting. For piping use, select option code F, which adds a lock ring.

Q10: What applications is the FMNV2 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 lines requiring precise and repeatable flow adjustment.
