MARPAC's three-piece design of the Tri-Pac™ E325/ E525 Ball Valve includes a true swing out body. In addition, the threaded end ball valve does not include any body lips or body rings to interfere with the in-line maintenance feature. 

MARPAC offers this ball valve in both the regular port design (E325) for economy purposes and the full port design (E525) for minimum pressure drop. This allows the MARPAC Tri-Pac™ E325/ E525 to boast both high standards and quality in a rugged design.

Large, enclosed body bolts along the ball valve maintain the body seal even through temperature fluctuations. The fully enclosed bolt thread configuration also protects against corrosion, which is essential for API-607 fire test qualification. 


  • Size range: 1/4" to 2" 
  • Regular and Full port designs available  
  • In-line repairability provided by three-piece swing out design
  • Maximized seal integrity due to the dual packing feature
  • Vacuum to 3000 psi
