Control valve combats vibration, cavitation and noise

10 November 2020

Emerson has introduced the Fisher V280 full-bore trunnion-mounted ball control valve for severe and specialty pressure, flow and process control applications.

The valve provides dynamic process control by utilising a drive train designed to guide the shaft and properly absorb energy. Available attenuators for liquid and gas process fluids offer an effective solution for combatting the negative consequences of cavitation, such as vibration, erosion and noise.

The body connections of the valve have been re-engineered to simplify the design and reduce the number of parts, while utilising the same construction for the inlet and outlet. This allows an easy retrofit of single or dual ball seals with standard or customised noise attenuating aerodomes or anti-cavitation hydrodomes on the inlet, outlet or both. Typical applications include midstream oil and gas, particularly compressor anti-surge service.
