Flow Coefficients
See Fisher Catalog 12
Flow Characteristic
Modified equal percentage (see figure 3)
Face-to-Face Dimensions
Consistent with
J ISA S75.04 and IEC 60534-3-2
face-to-face dimensions
Option for CL150
J ASME B16.10-short
Standard Flow D irection
Forward flow direction is into the convex face of the
V-notch ball. The valve with the attenuator must be
placed in the forward flow direction for the
attenuator to be effective.
Actuator Mounting
J Right-hand or J left-hand as viewed from
upstream end of valve. Counter-clockwise to close for
both mounting styles.
Maximum Ball Rotation
90 degrees
Valve/Actuator Action
With diaphragm or piston rotary actuator,
field-reversible between
J push-down-to-close (extending actuator rod closes
valve) and
J push-down-to-open (extending actuator rod opens
valve)
ENVIRO-SEAL Packing
This optional packing system provides improved
sealing, guiding, and transmission of loading force to
control liquid and gas emissions.
Options
J Alloy construction materials, and other c ommon
valve parts are available upon request,
J Materials
that comply with NACE MR0175-2002 for sour
service. Refer to Bulletin 51.3:Vee-Ball, or contact
your Emerson Process Management sales office
