Parker MAB series manual, pneumatic and electrically actuated two-way and three-way ball valves are designed for quarter and half turn media shutoff or switching applications up to 15,000 psi. Our single-piece trunnion style ball design and re-torqueable seats make the MAB series ideal for severe service applications. The end connector design enables a variety of end connections and combinations for specific customer applications. Please see Parker Autoclave Engineers Ball Valve Literature for additional connection options.

NOTE:
  • For 2507 Super Duplex option, replace -SS with -2507 and use -XF.
  • All vent connections are sized at 1/4 FNPT. Other vent connections are available upon request. Please consult your local representative.
  • -XF Ferrules are required for 3/4" and 1" 316 SS or 2507 Super Duplex Tubing.
  • MADBB Valves cannot be repaired in field and as such, no repair kits are identified.
  • Dimensions for reference only, subject to change.
