The advanced design and materials of Hansen threaded refrigerant shut-off valves make them far superior to commonly-available products, especially in regard to non-leakage of seats, stems, and bonnets. 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.
Socket Weld Shut-Off Valve
Butt Weld Shut-Off Valve
Hansen low pressure drop refrigerant shut-off valves are designed to be butt-welded directly to steel piping, thereby eliminating potential leaky flanges or threaded joints and simplifying installation. Cast steel bodies are lightweight, yet have substantial wall thickness to overcome corrosion potential.
