Description
The Hansen GW800H is an 8" (200 mm) butt weld globe shut-off valve with a handwheel, 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 8" butt weld valves: gasket kit 50-1084, bonnet assembly kit 50-1085, disc kit 50-1088 and handwheel kit 50-1090.

Common questions
What is the difference between the GW800H and the GW800C?
Both are 8" butt weld globe valves. The H suffix means this valve ships with a handwheel, while the GW800C ships with a seal cap. 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.
