電動(dòng)球閥：產(chǎn)品概述及特點(diǎn)“乾QY儀”系列電動(dòng)球閥旋轉(zhuǎn)90°即可全關(guān)全開，與相同規(guī)格的閘閥和截止閥比較。閥體通道和連接管徑相等并成一直徑，介質(zhì)幾乎可以毫無損失的流過。球閥是一種重要的閥類，在石油化工和長(zhǎng)輸管線等領(lǐng)域有廣泛應(yīng)用。它的關(guān)閉件是一個(gè)帶孔的部分球體，球體隨閥桿轉(zhuǎn)動(dòng)，實(shí)現(xiàn)閥門的開啟或關(guān)閉。其特點(diǎn)如下：適用于兩位切斷、調(diào)節(jié)的場(chǎng)合。電動(dòng)球閥可實(shí)現(xiàn)對(duì)石油、化工、造紙、冶金、污水處理、油罐車等運(yùn)輸管道內(nèi)介質(zhì)的切斷和流通。密封性能優(yōu)良、流通能力大、裝卸維護(hù)方便、流阻小、密封可靠，甚至切斷。電動(dòng)電動(dòng)閥門體積小、重量輕、推力大、功能強(qiáng)、伺服放大器內(nèi)裝、操作方便、可靠性高。流向可任意，可調(diào)范圍廣，能用于高壓和大口徑場(chǎng)合，控制高粘度，帶有纖維和細(xì)顆粒的介質(zhì)。直連方式，電動(dòng)執(zhí)行機(jī)構(gòu)內(nèi)置伺服系統(tǒng)，無須另配伺服放大器，輸入輸出信號(hào)4-20mA及380VAC電源即可控制運(yùn)轉(zhuǎn)。具有連線簡(jiǎn)單、結(jié)構(gòu)緊湊、動(dòng)作穩(wěn)定可靠等優(yōu)點(diǎn)Q941F-16 DN15/Q941F-16 DN25/Q941F-16 DN32/Q941F-16 DN40/Q941F-16 DN50/Q941F-16 DN65/Q941F-16 DN80/Q941F-16 DN100/Q941F-16 DN125/Q941F-16 DN150/Q941F-16 DN200/Q941F-16 DN250/Q941F-16 DN300/Q941F-16 DN350/Q941F-16 DN400/Q941F-16 DN450/Q941F-16 DN500/Q941F-16 DN600/Q941F-25 DN32/Q941F-25 DN40/Q941F-25 DN50 Q941F-25 DN65 Q941F-25 DN80 Q941F-25 DN100 Q941F-25 DN150 Q941F-25 DN200 Q941F-25 DN250/Q941F-25 DN300/Q941F-25 DN350/Q941F-25 DN400/Q941F-25 DN450/Q941F-40 DN25/Q941F-40 DN32/Q941F-40 DN40/Q941F-40 DN50/Q941F-40 DN65/Q941F-40 DN80/Q941F-40 DN100/Q941F-40 DN125/Q941F-40 DN150 Q941F-40 DN200/Q941F-40 DN250/Q941F-40 DN300/Q941F-40 DN350/Q941F-40 DN400/Q941F-40 DN450/Q941F-40 DN500/Q941F-40 DN600/Q941F-40 DN700/Q941F-64 DN25/Q941F-64 DN32/Q941F-64 DN40/Q941F-64 DN50/Q941F-64 DN65/Q941F-64 DN80/Q941F-64 DN100/Q941F-64 DN125/Q941F-64 DN150 Q941F-64 DN200/Q941F-64 DN250/Q941F-64 DN300/Q941F-64 DN350/Q941F-64 DN400/Q941F-64 DN450/Q941F-640 DN500/Q941F-64 DN600/Q941F-64 DN700/Q941F-100 DN25/Q941F-100 DN32/Q941F-100 DN40/Q941F-100 DN50/Q941F-100 DN65/Q941F-100 DN80/Q941F-100 DN100/Q941F-100 DN125/Q941F-100 DN150 Q941F-100 DN200/Q941F-100 DN250/Q941F-100 DN300/Q941F-100 DN350/Q941F-100 DN400/Q941F-100 DN450/Q941F-100 DN500/Q941F-100/Q911F-16CP DN15/Q911F-16CP DN20/Q911F-16CP DN25/Q911F-16CP DN32/Q911F-16CP DN40/Q911F-16CP DN50/Q911F-16CP DN65/Q911F-16CP DN80/Q911F-16CP DN100/Q911F-16CP DN125/Q911F-16CP DN150/Q911F-16CP DN200
