Stainless Steel Needle Valve – 3/8" Tube OD | Union Bonnet | PTFE Packing | 6000 PSI (SUNV2-S-6)
The SUNV2-S-6 is a 3/8" union bonnet needle valve designed for precise flow control in high-pressure, high-purity systems. With a 6000 PSI rating, non-rotating stem tip, and PTFE packing, it delivers reliable, leak-tight sealing and chemical resistance in instrumentation panels, analyzer setups, and sanitary gas systems.
This valve offers smooth, low-torque operation and minimal fugitive emissions—ideal for Clean-in-Place (CIP) applications, lab builds, and OEM skids. The SUNV Series supports straight or angle flow configurations, and integrates cleanly with Swagelok® style compression fittings and stainless steel process lines.
Whether you’re managing gas delivery, sampling fluids, or designing tight-space process systems, the SUNV2-S-6 gives you consistent metering, rugged reliability, and sanitary-grade compatibility.
Key Benefits
- Control: Non-rotating stem tip allows for precise metering and shutoff
- Sealing: PTFE packing provides leak-tight performance and chemical resistance
- Durability: Handles pressure surges, system cycling, and corrosive media
- Compatibility: Works with 3/8" stainless tubing and instrumentation-grade fittings
- Material: 316 stainless and Alloy 400 body supports clean and regulated environments
Typical Applications
- Clean-in-Place (CIP) instrumentation systems
- Analyzer panels and sampling stations
- OEM gas and liquid control systems
- Sanitary stainless fluid processors
- High-purity lab or industrial skids
