Description
The Hansen AW500C is a 5" (125 mm) butt weld angle shut-off valve with a seal cap, built for industrial refrigeration piping. It welds directly into steel pipe, so there are no flanged or threaded joints, and it uses Hansen's non-leak seal plus stem packing design to minimize stem leakage.
Service kits listed by Hansen for 5" butt weld valves: gasket kit 50-1082, bonnet assembly kit 50-1080, disc kit 50-1086 and seal cap kit 50-1091.

Common questions
What is the difference between the AW500C and the AW500H?
Both are 5" butt weld angle valves. The C suffix means this valve ships with a seal cap, while the AW500H ships with a handwheel. Hansen notes that the handwheel and seal cap are interchangeable.
Which refrigerants is it suitable for?
Hansen lists the butt weld shut-off valve line for R717 (ammonia), R22, R134a, R507a, R404a, R744 (CO2) and other Hansen-approved refrigerants.
Specifications are based on Hansen Technologies Bulletin G359d (Butt Weld Shut-Off Valves, Nov 2019). Confirm fit, ratings and application requirements before ordering.
