Fisher V280 full-bore trunnion-mounted ball control valves for severe and specialty pressure, flow, and process-control applications, use a drive train to guide the shaft and absorb energy.
Available attenuators for liquid and gas process fluids offer a solution for combatting the negative consequences of cavitation, such as vibration, erosion, and noise. Valve body connections are reengineered to simplify the design and reduce the number of parts, while using the same construction for the inlet and outlet. This allows retrofit of single or dual ball seals with standard or customized noise-attenuating aerodomes or anti-cavitation hydrodomes on the inlet, outlet, or both. The ANSI class 900 valves are available in 6-, 8-, 10-, 12-, and 16-in. sizes.
