ZHSN系列電動直通雙座調(diào)節(jié)閥由DKZ型系列直行程電動執(zhí)行機(jī)構(gòu)和直通雙座閥兩部分組成，以單相交流220V電源為動力，
接受0~10mA或4~20mA直流信號，自動地控制調(diào)節(jié)閥開度，達(dá)到對管道內(nèi)流體的壓力、流量、液位等工藝參數(shù)的連接調(diào)節(jié)。
該產(chǎn)品具有動作靈敏、能源取用方便、信號傳輸迅速等特點。廣泛應(yīng)用于電力、冶金、化工、輕紡工業(yè)自動控制系統(tǒng)中。

4、允許壓差
標(biāo)準(zhǔn)組配的電動雙座調(diào)節(jié)閥考慮到介質(zhì)對閥芯、閥座的沖蝕和高壓差引起的噪聲、振動，一般情況下，閥的壓差不應(yīng)
超過1MPa，如壓差較高，則應(yīng)采取相應(yīng)的工藝措施。
