Description
The Hansen GW301C is a 3" (80 mm) butt weld globe 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 3" butt weld valves: gasket kit 50-1043, bonnet assembly kit 50-1044, disc kit 50-1045 and seal cap kit 50-1038.

Common questions
What is the difference between the GW301C and the GW301H?
Both are 3" butt weld globe valves. The C suffix means this valve ships with a seal cap, while the GW301H 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.
