Fisherr V260 Ball Control Valve
The Fisher V260 is a full-bore control valve designed
from the ground up with features for optimized
pressure, flow and process control. An integral drilled
attenuator controls noise and vibration from high
pressure drop liquids and gases. The splined shaft
connection to the actuator reduces lost motion.
The V260A with Aerodome attenuator, V260B with
Hydrodome attenuator, and V260C Ball Control Valves
(figures 1 and 3) combine the efficiency of a rotary
valve with the energy-dissipating capability of a special
trim to provide improved performance for demanding
applications. The valve is available with single, dual, or
dual block-and-bleed seal options (see the
Specifications table).
The trim design of the V260A is used in gas service to
reduce noise effects that cause pipeline vibration. The
V260B provides improved performance for demanding
applications such as pump bypass and pipeline
take-off. The trim is designed for liquid service to help
eliminate or reduce cavitation and associated pipeline
noise and vibration. The V260C full-bore ball valve is
designed for automated control in bypass, batch,
monitor, and emergency shutoff service applications,
and it presents little or no restriction to flow.



Aerodynamic Performance-- Up to -20 dBA
acoustical attenuation can be achieved for the
V260A within a single stage construction.
Dual-stage construction can provide up to -25 dBA
attenuation.



Improved Service Life-- The attenuator is not part of
the seal assembly. The seal wipes to ball surface, not
the attenuator, promoting increased service life.



Trim Versatility-- Key valve components, such as
valve body, ball, shaft and bearings, are
interchangeable between the V260A, V260B and
V260C. This feature allows you to reduce your spare
parts inventory and maintenance time.

The V260 full-bore ball valve is available with
composition seals, and process type stem packing for
improved service life.
Unless otherwise noted, all NACE references are to
NACE MR0175-2002.

Features


Excellent Flow Control-- The splined ball to shaft
connection, splined shaft to actuator connection,
double power-end bushing assemblies, and
trunnion guiding, all provide improved dynamic
control.

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).

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)

For Single-Seal and Dual-Seal Construction
(Except where further limited by the pressuretemperature rating of the valve body):

Maximum Ball Rotation

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)

Actuator Mounting

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

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)

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.

designed for demanding applications requiring long
service life, with a reduction in maintenance time
and costs.



Broad Hydrodynamic Applications-- Single, dual,
and three-stage attenuators for the V260B may be
provided for a varying range of applications. A Kc

value of 1.0 is achievable depending on service
conditions.



Flexible Applications-- The attenuator is active
throughout the ball rotation for very demanding
