Description
The Hansen ASB075C is a 3/4" (20 mm) socket weld angle shut-off valve with a seal cap 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.
Hansen lists bonnet assembly kit 50-1094 for 1/2" and 3/4" socket weld shut-off valves.
