510D 系列調(diào)節(jié)閥采用了多級(jí)降壓式套筒，完全控制了流經(jīng)閥內(nèi)件的流體流速，故可大幅度降低高壓差氣體或蒸汽所產(chǎn)生的噪音，也可有效防止液體產(chǎn)生氣蝕現(xiàn)象，是一種無(wú)氣蝕損傷、低噪音、控制流體穩(wěn)定的經(jīng)濟(jì)型調(diào)節(jié)閥。

The Series 510D valves are engineered specifically for critical anti-cavitation and low noise applications on liquids, gases or steam. Multi-stage cage controls flowing velocities in the valve trim by forcing the process fluid to follow a tortuous path of right-angle turns. The resistance to flow provided by these turns reduces fluid velocities significantly. Therefore, a vena contracta is never formed in the trim and noise and cavitation are stopped before they can start.
