Anderson Greenwood hand valves are suitable for all instrument isolation duties, giving you bubble tight shut-off time after time. With metal or soft seats for gas, vapor or liquid applications, rated up to 10,000 psig [690 barg] and available in a range of standard and exotic materials, there is a hand valve for even the most severe service.

Features & Benefits:

  • Replaceable soft seat allows replacement of the soft seat insert without removing the valve from the line. It operates in dirty service with repetitive bubble-tight shut-off.
  • Packing below threads prevents lubricant washout, thread corrosion, and keeps solids from entering the thread area, which can cause galling. It also prevents process contamination.
  • Adjustable Teflon® packing adjusts easily: loosen jam nut, tighten bushing slightly, then retighten jam nut. Decreases packing replacement downtime and increases valve life.
  • Dust cover prevents lubricant washout and keeps contaminants (dirt, rain, etc.) out of bonnet assembly.
  • Safety back seating prevents stem blowout or accidental removal while in operation and provides a metal-to-metal secondary stem seal while in the full open position.
  • Chrome plating of 316 SS stem prevents galling or freezing of stem threads when similar metals mate. CS valves use a 303 SS stem.
  • Rolled threads provide additional thread strength. The stem, bonnet, and male NPT threads are rolled, not cut.
  • Mirror stem finish burnished to a 16 RMS finish in the packing area enables smooth stem operation and extends packing life.
  • Straight-through flow path provides high flow capacity, bi-directional flow, and rodding capabilities.
  • Body-to-bonnet seal is metal-to-metal in constant compression below the bonnet threads. Prevents bonnet thread corrosion, eliminates possible tensile breakage of bonnet, and gives a reliable seal point.
