The advanced design and materials of Hansen refrigerant shut-off and hand expansion valves make them far superior to commonly available products. The extended neck of the bolted bonnet design greatly simplifies insulation, and allows compliance with industry guidelines for insulation thickness. In addition, non-leak seats, stems, and bonnets virtually eliminate the possibility for refrigerant leakage. Anyone who has experienced the failure of a shut-off valve at a crucial time will take care to insist upon these highly reliable valves.
