Features
- 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.
