Item # 8MP7-MADBB6LPK-V-SS, MADBB Double Block and Bleed Ball Valves On Parker Hannifin Instrumentation Products Div.

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.
