provides improved performance for demanding applications such as pump bypass and pipeline take-off.
The attenuator trim is designed for liquid service to help eliminate or reduce cavitation and associated pipeline
noise and vibration.
The V260B is a full bore ball valve designed with features for optimized pressure, flow, and process control.
An integral, drilled attenuator controls noise and vibration from high pressure drop liquids. The splined shaft
connection to the actuator reduces lost motion.
The V260B with Hydrodome attenuator combines 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 and dual Hydrodome configurations.
The Hydrodome attenuator is active throughout the ball rotation for very demanding services or a characterized
attenuator (as shown) is used to match the service conditions.
