Multi-Port Selection
Four flow types are available, with a wide
variety of flow pattern combinations.
Refer to the QCI Valve Flow Pattern Combination
chart
(download our full brochure)
for flow types and combinations available. |
One Piece Rotor and
Stem
The one piece construction eliminates a
source of wear and repair common to the typical
ball valve design. Eliminates stem leakage
problems. |
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. |
Maintenance Free
The wiping/agitation action generated by the
rotation of the leaf seals, along with the
rotor, breaks up material and wipes it free.
The independent leaf seal design also eliminates
the need for lubrication. No
adjustments....No maintenance. |
Top Entry
The ability to remove all internal parts
through the top of the valve eliminates removal
of the valve from the pipeline, should service
be required. |
Transitional Flow
The QCI rotor valve design allows for
transitional flow to occur when changing valve
positions. Transitional flow eliminates
dead heading problems associated with positive
displacement pumps. For minimal
transitional flow designs, consult factory. |
High Flow
The majority of the QCI rotor valves are
full-port, with only a few sizes or types having
a minimum port reduction. The maximization
of port diameter reduces the pressure drop
across the valve, thus increasing flow.
Consult the dimensional information contained in
our brochure for actual port diameter of the
valve and rotor type that best suits the
application. |
End Connections
The information contained in our brochure is for QCI Rotor
Valves with FNPT (Female National Pipe Thread)
or ANSI 150# Flange end connections. The
FNPT and 150# Flange end connections are the
most commonly used in process industries today.
These ends offer a rigid plumbing system, yet
still allow for valve removal from the line.
QCI Rotor Valves with these ends are available
in a variety of materials. |
