The QCI Full Port 120˚ "Piggable" 3-way Rotor Valve is designed for applications where it's long radius flow passage minimizes the pressure drop across the valve and allows the passage of a pipeline "pig".  This valve replaces cumbersome piping arrangements and offers an efficient "piggable" piping system. 

Major advantages of an efficient "piggable" piping include:

  • Shorter Duration CIP or Steam Sterilization Cycles
  • Product Recovery
  • Waste Disposal
  • Excellent choice for applications, such as viscous fluids, or slurries, where the hard 90˚
    turn of a standard 3-way valve is restrictive to that application.

Design Advantages:

Piggable
Allows the passage of a pipeline "pig".
Maintenance Free
No adjustments or lubrication required.
Full Port to the Pipe I.D.
The inside diameter of the port is constant with the inside diameter of the pipe.  This eliminates areas for the "pig" to hang up, or product buildup.  Full Port to the Pipe I.D. minimizes the pressure drop across the valve, which offers higher Cv values.
Self Lubricating
The independent Leaf Seal design eliminates the need for lubrication.
120˚ Porting/Long Radius Flow Passage
The radius of the sweeping flow passage in the rotor, matches the long radius tube elbow
(rad. =1½ x port dia.).  This eliminates the hard 90˚ turn of a standard 3-way valve.
Self Cleaning
The wiping/agitation action generated by the rotation of the Leaf Seals along with the Rotor, Breaks up material and wipes it free.
One Piece Rotor & Stem
The one piece construction eliminates a source of wear and repair common to the typical ball valve design.  This construction eliminates stem leakage problems.
Top Entry
The ability to remove all internal parts through the top of the valve eliminates removal of the valve from the pipeline, should servicing be required.
Cavity Free
The independent Leaf Seal design eliminates the large cavities common to the typical ball valve.  The Leaf Seal design also eliminates the need for cavity fillers, which still create stagnant seams for product to get into.
