Specifications
Valve Body Sizes and End Connection Styles
NPS J 8, J 10, J 12, J 16, J 20, and J 24 flanged
valves with CL150, CL300, or CL600 raised-face
flanges compatible with ASME B16.5.
Consult your Emerson Process Management sales
office for other end style connections.
Maximum Inlet Pressures and Temperatures
(1)
Consistent with CL150, CL300, or CL600
pressure-temperature ratings per ASME B16.34
Maximum Allowable Shutoff Pressure Drop
(1)
.
For Single-Seal and Dual-Seal Construction
(Except where further l imited by the pressure-
temperature rating of the valve b ody):
J CL150: 20 bar (285 psi) at 38_C(100_F)
J CL300: 51 bar (740 psi) at 38_C(100_F)
J CL600: 103 bar (1480 psi) at 38_C(100_F)
Flow Characteristic
J Modified linear with single high density attenuator,
J Modified equal percentage with single
characterized attenuator (see figure 2), or
J Modified equal percentage without attenuator
Flow and Shutoff Direction
Unidirectional flow for V260 is forward flow. Seal is
upstream.
J Single Seal Constructions: Should be used for
unidirectional flow and unidirectional shutoff only.
J Double Seal Constructions: V260A and V260C may
be used for unidirectional and bidirectional flow.
V260B should be used for unidirectional flow only for
effective anti-cavitation protection. Bidirectional
shutoff requires the dual seal construction.
Flow Coefficients
See Fisher Catalog 12
Shutoff Classification
Single-Seal Composition Constructions: 0.001% of
maximum valve capacity (less than 10% of ANSI/FCI
70-2 Class IV and IEC 60534-4)
Dual-Seal Composition Constructions: 0.001% of
maximum valve capacity (less than 10% of ANSI/FCI
70-2 Class IV and IEC 60534-4)
Seal Material and Temperature Capability
(1)
Standard: J POM (polyoxymethylene) -29 to 82_C
(-20 to 180_F)
Optional: J PTFE/PEEK
(2)(3)
-29 to 93_C
(-20 to 200_F)
Maximum Ball Rotation
90 degrees
Actuator Mounting
Right-hand or left-hand mounted as viewed from the
valve inlet for forward flow
Packing Arrangements
PTFE Packing: Standard construction
(see figure 4)
ENVIRO-SEALt Packing: This optional packing
system provides improved sealing, guiding, and
transmission of loading force to control liquid and gas
emissions. Contact your Emerson Process
Management sales office for availability of
ENVIRO-SEAL packing (see figure 4)

Options
J Double block-and-bleed applications (Dual-seal
construction is required), J Two Stage V260A
Attenuator, J Two or Three Stage V260B Attenuator,
J CL900 flanges, J Ring type joint flanges
1. The pressure/temperature limits in this bulletin and any applicable standard or code limitation for this valve should not be exceeded.
2. PTFE stands for Polytetrafluoroethylene, and PEEK stands for PolyEtherEtherKetone.
3. Temperature limit of PTFE/PEEK is limited due to standard Nitrile O-Ring. Contact your Emerson Process Management sales office for higher temperature options, up to 232_C (450_F).
Features (continued)
Sour Service and Sour Crude Oil Capability--
Optional materials are available that comply with
NACE Standard MR0175-2002.
Tight Shutoff-- Self-adjusting seal(s) that are
pressure assisted provide tight shutoff for long
reliable service. The design incorporates a heavy
duty S31600 stainless steel carrier that retains the
composition seal for full-rated pressure drop
service.
