Design Features

•  Standard trim is API trim 8 for carbon steel valves, API trim 5 for chrome alloy valves, and API trim 10 for CF8M (T316) valves for optimal performance under normal conditions. Other trim materials are available on request.
•  Seat faces lapped for smooth finish and superior sealing.
•  Wall thickness per heavy wall API 600 requirements.
•  Swivel disc for improved seat alignment and longer life.
•  Each valve is shell and seat pressure tested per industry standard API 598.
•  Check valves are suitable for service in horizontal line with cap vertical or in a vertical line with flow upward.
•  Carrier Pin is confined within the body wall and is not accessible from the exterior, thus no side body penetrations, eliminating a common leak path, on classes 150 through 600.
•  End Flanges have the following raised faces per ASME B16.5: 
          Classes 150-300: 1/16” (2mm).
          Classes 600-1500: 1/4” (7mm).
•  Each valve has a unique certification number that is traceable to the valve certification sheet which includes MTR data, pressure test, inspection result and certificate of conformance.
•  Other available options as follows:
  -Alternate valve materials such as chrome and stainless steel alloys
  -Alternate trim materials
  -Drain and other auxiliary connections
  -NACE service
  -Special cleaning for applications such as oxygen or chlorine
 -Other options available as specified
