• Compact, maximum-flow design
• Low operating torque
• 2- or 3-way flow patterns
• Panel mounting
• Heavy-duty handle indicates flow direction.
• Bottom-loaded stem:
  • prevents stem blowout
  • enhances system safety.
• Trunnion-style ball:
  • prevents ball blowout
  • contributes to low operating torque.
• Spring-loaded seats:
  • provide leak-tight integrity in both low and high-pressure systems
  • contribute to low operating torque
  • reduce seat wear from pressure surges.
• Low-temperature and high-pressure, low-temperature service trunnion ball valve models available
• ECE R110-type approval valves available

Testing
Every Swagelok trunnion ball valve is factory tested with nitrogen at 1000 psig (69 bar). Seats have a maximum allowable leak rate of 0.1 std cm³/min. Shell testing is performed to a requirement of no detectable leakage with a liquid leak detector.

Cleaning and Packaging
All Swagelok trunnion ball valves are cleaning and packaged in accordance with Swagelok Standard Cleaning and Packaging (SC-10). Cleaning and packaging in accordance with Swagelok Special Cleaning and Packaging (SC-11) is available.
