Socket Weld Shut-Off Valve

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.
  • Also available as Hand Expansion Valve
  • Chain actuators available 1½”–2½” (40mm–65mm)
  • Suitable for R717 (ammonia), R22, R134a, R507, R404a, R744 (CO2) and other Hansen approved refrigerants
  • Valves for 600 psig (41 bar g) SWP available
  • Extended neck available for additional insulation clearance

Advantages

Compared to conventional stem seal designs, Hansen’s patented non-leak seal plus stem packing virtually eliminates stem seal leakage. In addition, the stem is polished to avoid packing wear. The precision stem threads avoid stem wobble and the packing nut is close fitting to remove dirt particles and frost from the stem. This results in infrequent maintenance or tightening and almost no refrigerant loss.

Hansen valves are designed with anti-spin seat discs. High velocity gas can sometimes cause ordinary seat discs to fail over time. Hansen adds a snubber to prevent the seat disc from freely rotating when valve is in the open position.
