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.
Applications
Typical uses include:
Refrigeration system suction, liquid, recirculating liquid, hot gas, thermosyphon, and oil lines, using handwheel or seal cap models.
Steel pipe portions of halocarbon, commercial, industrial, and air conditioning systems, using seal cap models.
Valves are also available for other fluids such as propane, propylene, and glycol with compatible seals. Contact factory with specific fluid and application details for written approval.
The low friction, non-leak stem seal design permits low torque valve operation without the need to retighten the packing.
