Meet Swagelok 83 DXL

The Long lasting 3 way ball valve for your CNG station needs.

CNG dispensers located at filling stations represent a very challenging application requiring high pressures and frequent cycling. These conditions can result in costly premature failure in many 3-way valves. We have used our design experience and knowledge of the application to develop an innovative new valve to provide our customers with a solution in these situations. The 83DXL series valve has vastly improved cycle life performance in "fast fill" CNG dispenser applications and hence reduces the downtime from replacing and rebuilding valves.


Stainless steel 83 series 3-way ball valves are available for use in a variety of vehicle filling applications, covering pressure ranges up to 6000 psig (413 bar).


  • Significantly higher cycle life
  • Working pressures up to 6000 psig (413 bar)
  • 3/8 or 1/2 in. Swagelok® tube fitting or female NPT side ports
  • Bottom port is 1/4 in. female NPT end connection
  • 316 stainless steel materials
  • Compact, maximum-flow design
  • Low operating torque
  • A directional installation with 90 degree actuation for ease of operation during filling
  • 3-way design with vent port for ease of venting after fill
  • PEEK seats to reduce maintenance required in high-cycle applications
  • Trunnion-style ball: prevents ball blowout & contributes to low operating torque
  • Spring-loaded seats: provide leak-tight integrity & reduce seat wear from pressure surges
  • Bottom-loaded stem: prevents stem blowout & enhances system safety
