A4VSO泵具有泵具有噪音低、體積小、自吸能力好、可靠性高等優(yōu)點。在閉式系統(tǒng)上應(yīng)用，油泵變量過零位時一般柱塞泵都有托盤現(xiàn)象，唯獨D-A4VSO泵有效解決此類問題，因補油泵、控制泵可以串接、控制閥可以集成在泵蓋上，其結(jié)構(gòu)非常緊湊;另外，比例泵均帶有位移傳感器閉式反饋回路，其零位控制精度非常高。廣泛應(yīng)用于：冶金行業(yè)、鍛壓行業(yè)、船舶行業(yè)、船舶等等領(lǐng)域。A4VSO系列規(guī)格有40、71、125、180、250:;變量形式有恒壓，恒功率、液動、負(fù)載感應(yīng)、比例、伺服、壓力流量復(fù)合控制形式;有開式系統(tǒng)泵和閉式系統(tǒng)泵。A10-FR01B-12,A10-FR01C-12,A10-FR01H-12,

彈性密封閥門，密封圈可以鑲嵌在閥體上或附在蝶板周邊。采取金屬密封的閥門一般比彈性密封的閥門壽命長，但很難做到完整密封。金屬密封能適應(yīng)較高的工作溫度，彈性密封則具有受溫度限制的缺點。假如請求電動球閥作為流量把持使用，重要的是準(zhǔn)確選擇閥門的尺寸和類型。電動球閥的構(gòu)造原理尤其合適制造大口徑閥門。電動球閥不僅在石油、煤氣、化工、水處置等一般產(chǎn)業(yè)上得到普遍運用，而且還利用于熱電站的冷卻水體系。常用的電動球閥有對夾式電動球閥和法蘭式電動球閥兩種。
