Gas Process Flow Control Solution — PORTER LB-366 NVL-003F | Thermal Mass Flow Controller Series
Where This Product Is Used
The PORTER LB-366 NVL-003F thermal mass flow controller (MFC) is engineered for precision gas flow regulation in demanding industrial and high-tech environments. Typical deployment scenarios include:
- Semiconductor Fabrication: CVD, PVD, and etch process chambers requiring stable, repeatable gas delivery (SiH₄, N₂, Ar, O₂, HCl, and specialty gases).
- Chemical Vapor Deposition (CVD): Precise precursor gas metering for thin-film deposition uniformity and yield control.
- Analytical Instrumentation: Carrier and calibration gas control in GC, mass spectrometry, and emissions analyzers.
- Industrial Gas Blending: Multi-component gas mixing skids for specialty gas production and quality assurance.
- R&D Laboratories: Bench-scale reaction studies, catalyst testing, and combustion research requiring traceable flow accuracy.
- Fuel Cell & Hydrogen Systems: Hydrogen and reformate gas metering in fuel cell test stands and electrolyzer rigs.

Why Engineers Specify This Model
- Proven Thermal Sensing Architecture: PORTER’s capillary-bypass thermal sensing delivers stable, drift-resistant measurement across a wide range of process gases.
- Normally Closed Fail-Safe Valve (NVL): The NVL suffix confirms a normally closed valve — critical for safety-critical gas systems where loss of power must default to flow shutoff.
- Drop-In Compatibility: LB-366 series units conform to industry-standard footprint and connector pinouts, simplifying replacement in existing tool sets without re-engineering gas panels.
- Long Service Life: Robust stainless steel construction and PORTER’s quality manufacturing heritage support multi-year service intervals in continuous-process environments.
- Broad Gas Compatibility: Suitable for inert, reactive, and mildly corrosive gases when appropriate wetted materials are selected.

Application-Specific FAQ
Q: What does “NVL” mean in the PORTER part number?
A: NVL designates a Normally Closed Valve. When de-energized (power off), the control valve closes, stopping gas flow. This is the preferred fail-safe configuration for most semiconductor and hazardous gas applications.
Q: Can this MFC control corrosive gases such as HCl or Cl₂?
A: The standard LB-366 uses 316L SS wetted surfaces with Viton seals. For aggressive corrosive gases, confirm wetted material compatibility and consider PORTER’s corrosive-service variants. Contact us for application review.
Q: Is recalibration required after long storage?
A: PORTER recommends recalibration after extended storage (>12 months) or if the unit has been exposed to contamination. Konmask can advise on local calibration service providers.
Q: What signal interface does the LB-366 NVL-003F use?
A: The standard interface is 0–5 VDC analog (setpoint and readback). Some configurations support 4–20 mA or RS-232/RS-485 digital. Confirm your specific unit’s interface from the label or calibration certificate.
Q: Can I replace an existing PORTER MFC with this unit without modifying my gas panel?
A: Yes — the LB-366 series uses a standard industry footprint. Verify port size, flow range, and connector pinout match your existing installation before swapping.
