Hansen ASB075H, 3/4 Shut-off Valve, Angle, Bolted BLT, Socket Weld, Handwheel

These  low  pressure  drop  refrigerant  shut-off  valves  are  designed  to  be  socket-welded  directly  to  steel  piping, thereby eliminating potential leaky flanges or threaded joints and simplifying installation. Forged and cast steel bodies are lightweight, yet have substantial wall thickness to help overcome corrosion loss. The cast steel body is rigid, reducing the potential for seat leakage due to flexing of the valve body under abnormal conditions. The “heart” of Hansen shut-off valves is the patented non-leak seal plus packing design. This seal design is used exclusively on Hansen shut-off valves and virtually eliminates stem seal leakage.

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 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 the use of chain actuation for crossover applications without the need to retighten the packing.
