Don-Nan Gas Valve

Orientation-maintaining gas valve for sucker rod pumps

Maintain proper valve orientation

The gas valve helps maintain proper valve orientation by allowing a small amount of fluid to reenter the pump and aide the standing valve ball in reseating itself on the downstroke. By maintaining proper valve orientation throughout the pumping cycle, the pump is less likely to incur damage due to working with sufficiently full fluid levels.


  • Increases pump fillage
  • Improves fluid production
  • Reduces component damage


  • Pressure tested to 5,000 psi [34.5 MPa]
  • Barrel and plunger mount options
  • 316 stainless steel for corrosion resistance
