Gas Distribution Solution – VERIFLO 0050-36242 | 3-Valve Manifold Series
Where This Product Is Used
The VERIFLO 0050-36242 3-Valve Manifold with Gas Line Weldment is engineered for high-purity gas distribution in the most demanding process environments. Typical deployment sites include:
- Semiconductor Fabrication (Fabs) – Integrated into gas panels for CVD, ALD, etch, and diffusion processes where precise, contamination-free gas delivery is critical.
- Specialty Gas Cabinets & VMBs – Used as the primary isolation and distribution manifold within valve manifold boxes (VMBs) handling toxic, pyrophoric, or corrosive process gases.
- Photovoltaic (PV) & LED Manufacturing – Deployed in MOCVD and PECVD reactors requiring ultra-clean gas switching with minimal dead volume.
- Research & Analytical Laboratories – Installed in gas chromatography supply lines and mass spectrometry carrier gas systems.
- Industrial Gas Distribution Panels – Applied in high-pressure manifold assemblies for inert, oxidizing, and flammable gas services.

Why Engineers Specify This Model
- Zero Dead-Leg Design – The integrated weldment eliminates tube stubs and dead legs that trap contaminants, ensuring process gas purity from source to point-of-use.
- Multi-SKU Interoperability – Cross-referenced as 944AOPLPNC3PWTS4275, 615-00325-000, and 0200-01271, making it a direct drop-in replacement across multiple OEM BOM revisions.
- Electropolished Flow Paths – Internal Ra ≤ 15 µin finish minimizes particle generation and moisture adsorption, critical for sub-10nm node processes.
- Helium Leak-Tested at Factory – Every unit ships with documented leak test certification, reducing commissioning time on-site.
- Compact Weldment Assembly – Pre-assembled gas line weldment reduces field installation complexity and eliminates potential leak points from field-made tube connections.

Application-Specific FAQ
Q: Is this manifold compatible with corrosive gases such as HCl, HF, or Cl₂?
A: The 316L SS body with electropolished finish provides good resistance to many corrosive gases at low concentrations. For highly aggressive chemistries, consult VERIFLO’s material compatibility guide or contact our engineering team.
Q: Can this unit be used with oxygen service?
A: Yes, provided the unit is cleaned for oxygen service (O₂ clean) per ASTM G93 / CGA G-4.1. Confirm cleaning status with your procurement team before installation.
Q: What is the difference between part numbers 615-00325-000 and 0200-01271?
A: These are internal cross-reference numbers used across different OEM and fab documentation revisions. Both refer to the same VERIFLO 0050-36242 assembly. Our team can provide a formal cross-reference letter upon request.
Q: Is pneumatic actuation available for this manifold?
A: Yes. Pneumatic actuator kits are available as accessories. Contact us with your actuation pressure and signal requirements.
Q: Do you provide a Certificate of Conformance (CoC)?
A: Yes. A CoC is available upon request at time of order. Please note this in your purchase order or email us after checkout.
