The Cameron WHEATLEY Series 822 check valve is designed to safely prevent backflow of liquid or gas in pipeline applications. The valve's beveled, self-aligning clapper and seat design incorporates a molded seal in the clapper for a bubble-tight primary seal and metal-to-metal secondary seal.


  • WCC, LCC, and CF8M models designed in accordance with ASME Spec B16.34
  • Materials of construction conform to NACE MR0175/ISO 15156 
  • Solid 316 stainless steel clapper and hanger that reduce the need for separate pins, bushings, and rollers
  • Compact valve geometry for reduced weight and space
  • Peroxide-cured Buna-N seals (FKM and HNBR optional)
  • Generous wrench area on body and hex-head threaded cover for easier installation and maintenance
  • Full opening
  • Horizontal or vertical flowup
