Fisherr V260 Ball Control Valve

TheFisherV260isafull-borecontrolvalvedesigned

fromthegroundupwithfeaturesforoptimized

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).

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.

The V260 full-bore ball valve is available with

composition seals, and process type stem packing for

improved service life.

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.

 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 a ssembly. T he 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.
