Description
The Hansen GW1000H is a 10" (250 mm) butt weld globe shut-off valve with a handwheel, built for industrial refrigeration piping. It welds directly to Schedule 40 steel pipe, avoiding the leak points of flanged or threaded joints, and uses Hansen's non-leak seal plus stem packing design to minimize stem leakage.
The straight-through globe flow path and low pressure drop design suit main and branch lines. Typical uses include ammonia system suction, liquid, discharge, recirculated liquid, hot gas, thermosyphon and oil lines.

Common questions
What is the difference between the GW1000H and the GW1000C?
Both are 10" butt weld globe valves. The H suffix means this valve ships with a handwheel, while the GW1000C ships with a seal cap. Hansen notes that the handwheel and seal cap are interchangeable.
Can this valve be used with CO2 or halocarbon refrigerants?
Hansen lists the butt weld shut-off valve line as suitable 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.
