What is a Compression Ball Valve?

A Compression Fitting Ball Valve is a quarter-turn shut-off valve with tube connection ends that use single or double ferrule compression fittings to create a strong, vibration-proof seal on metal or plastic tubing—no welding or threading required.

These are ideal for:

  • 1/4” to 1” OD tubing lines
  • Instrumentation & analytical systems
  • Chemical injection skids
  • High-purity or clean process setups

Key Features of Our Compression Ball Valves

  1. Tube Sizes: 1/4”, 3/8”, 1/2”, 3/4”, 1” (or 6mm–25mm OD)
  2. Tube Sizes: 1/4”, 3/8”, 1/2”, 3/4”, 1” (or 6mm–25mm OD)
  3. Material: SS316, SS304, Brass, Monel, Hastelloy
  4. Leak-tight design with PTFE or PEEK seats
  5. 2-way and 3-way flow configurations
  6. Blowout-proof stem, compact handle
  7. Factory tested for 100% leak integrity under pressure

Applications of Compression-End Ball Valves

  1. Gas sampling and analyzer systems
  2. Lab-scale chemical processing
  3. Instrumentation panels and impulse lines
  4. Skid-mounted chemical dosing units
  5. High-purity water and air systems
  6. Food and beverage quality testing setups
  7. Hydrogen, nitrogen, and inert gas lines
  8. Semiconductor and pharma cleanroom utilities

Installation & Maintenance Tips

  • Ensure tube end is clean, burr-free, and properly chamfered
  • Use appropriate ferrule alignment tools for perfect sealing
  • Avoid overtightening; follow manufacturer torque specs
  • For stainless steel tubing, use pre-swaging tools to ensure proper grip
  • Test for leaks using nitrogen or helium in sensitive systems

FAQs

Yes—our fittings are dimensionally compatible with industry-standard double ferrule systems.

Yes—with SS316 construction and PEEK seats, they can handle gas services up to 6000 PSI.

Yes—electropolished and degreased versions are available on request for high-purity or pharma environments.

For small-bore valves, manual operation is standard. However, panel-actuated or compact automation options are available.
