Product Bulletin 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. 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.
