Description
The Hansen AS200H is a 2" (50 mm) socket weld angle shut-off valve with a handwheel for industrial refrigeration systems. It socket-welds directly to steel pipe, eliminating flanged or threaded joints, and uses Hansen's non-leak seal plus stem packing design to minimize stem leakage.
Typical uses include ammonia system suction, liquid, discharge, recirculated liquid, hot gas, thermosyphon and oil lines.
