Hansen ASB050H, 1/2 Shut-off Valve, Angle, 4 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.Key Features:Non-leak Seal Plus PackingPolished Stainless Steel StemBackseat for Seal ReplacementBall BearingsTaper SeatAnti-spin Seat DiscAdditional Features:Globe and angle valves availableLow pressure drop designInterchangeable handwheel or seal capTeflon seat discAlso availbel as Hand Expansion ValveChain actuators available 1-1/2" to  2-1/2" (40mm-65mm)Suitable for R717 (ammonia), R22, R134a, %507, R404a,, R744 (CO2) and other Hansen approved refrigerantsvalves for 600 psig (41 bar g) SWP availbleExtended neck availble for additional insulation clearance
