GSB051H Hansen 1/2" Shut-off Valve, Globe, Bolted Bonnet, Socket Weld, Handwheel, T-Style

The advanced design and materials of the Hansen Steel Body Socket Weld Refrigerant Valves make them stronger and far superior to other commonly available products. This is especially true in regard to leakage from seats, stems, bonnets, and piping connections. Socket weld steel bodies permit these valves to be quickly and easily welded directly into piping without the inconvenience of pipe threading or using bulkier iron-flanged valves with socket weld steel flanges requiring bolts, nuts, and gaskets. Compared to butt weld valves, the Hansen socket weld bodies allow quicker welding, easier pipe alignment, and cleaner pipe and valve interiors.

Applications:

Typical uses include:

• Ammonia refrigeration system suction, liquid, discharge, 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 avilable 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 permit  the use of chain actuation for crossover applications without the need to retighten the packing.
