Description
The Hansen AWE301H is a 3" (80 mm) butt weld angle shut-off valve with a handwheel and an extended neck bonnet, 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.
Hansen lists extended neck gasket kit 50-1166 and extended neck bonnet assembly kit 50-1167 for 3" extended neck valves, plus handwheel kit 50-1037.

Common questions
What is the difference between the AWE301H and the AWE301C?
Both are 3" butt weld angle valves. The H suffix means this valve ships with a handwheel, while the AWE301C ships with a seal cap. Hansen notes that the handwheel and seal cap are interchangeable.
Why choose an extended neck valve?
Hansen states its extended neck bonnets (1/2" through 4") meet or exceed the recommended low temperature insulation thickness dimensions of the IIAR Piping Handbook, and the stainless steel trim is recommended where severe corrosive conditions exist.
Specifications are based on Hansen Technologies Bulletin G359d (Butt Weld Shut-Off Valves, Nov 2019). Confirm fit, ratings and application requirements before ordering.
