Multi Port Ball Valves

PBM Multiport Ball Valves

MP/MI Series 4

  • True-Bore® or Full-Port
  • Optional Body Cavity Fillers
  • Stainless & Carbon Steel
  • 3-, 4-, & 5-Way Valves

MP Series 1

  • Bronze, Iron & Stainless Steel
  • 3-, 4-, & 5-Way Valves


  • The Adjust-O-Seal® design incorporates an engineered space between the valve body and end fittings. This unique feature allows the valve seats to be restored in-line to a leak-tight condition. This adjustment can be repeated several times to compensate for normal wear.
  • Internal design produces a bubble-tight seal.
  • Spring-loaded washers create an adjustable live-loaded stem assembly for positive sealing.
  • Encapsulated seats (MP Series 4) and body gaskets eliminate cold flow (1/2" – 4").
  • Standard bottom-entry stem provides protection from inadvertent stem removal. Engagement between the slot and ball is specially suited for high torque applications.
  • Indexed ball and stem eliminate incorrect reassembly following routine maintenance.
  • Manual safety nuts maintain stem assembly, live-loading, and factory-prepared packing in instances where the handle may be removed for any reason.
  • Stainless steel handles with vinyl end covers are designed for a sure grip. Stem markings visually indicate flow direction.
  • Stainless steel balls are precision machined and polished to reduce torque and flow resistance, and extend seat life.
  • Compact, low profile design facilitates installation in areas with tight space restrictions.
  • In some processes, a single Multi-Port ball valve can replace several 2-way valves in a piping system, reducing costs and simplifying flow control with actuation. Multi-Port valves can also be tandem or manifold mounted to further centralize control.
  • Transflow, the gradual media flow that occurs as one port opens as another closes, prevents dead-heading and damage to pumps. Note: Transflow will not occur on some bottom entry flow patterns.
  • Full-port diameters minimize pressure drops.
  • True-Bore® design is standard in MI Series.
  • Having either four or five seats ensures tight closure under pressure differentials up to 300 psig.
  • Multiple seating in a true Multi-Port valve enables shutoff and directional control in a single valve. Multi-Port valves are ideal for recirculation, mixing, and blending operations.
  • Multi-Port valves are ideal for manual or fully automated operation.
  • Optional body cavity fillers on 3-, 4-, and 5-way valves minimize areas where media could become trapped and contaminate the process.
  • Top entry access on 1/2" thru 4" sizes facilitates inspection and packing replacement.
  • Stem assembly accommodates PBM Direct Mount Actuation for improved alignment and increased cycling life.
  • Stainless steel brackets are strong, durable, and corrosion-resistant to facilitate wash-down.
  • End fitting O-rings on sizes 1/2" thru 4" absorb thermal cycle abuse.
