多段式閥芯型閥門(mén)適合于在極其苛刻的工況條件下對(duì)高溫、高壓或高壓差液體的精確控制。能防止液體產(chǎn)生空化氣蝕、減少高速流體對(duì)閥內(nèi)件的沖刷、降低噪音；尤其適合于對(duì)含有雜質(zhì)或固體顆粒流體的控制。由于具有使作用在閥芯上的流體壓力平衡的結(jié)構(gòu)，因此只須用較小的操作力便可達(dá)到穩(wěn)定調(diào)節(jié)，能夠承受較高的工作壓差。

Multi-step plug control valves provide smooth and accurate capacity control of high pressure drop liquids without cavitation, erosion, vibration and high noise levels compare with single seated valves. It is particulary suited for appications invovling fluids with entrained particles. This series is characterized by pressure balanced type trim for very high pressure drops.
