Description

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
