DZDLP型電子式電動單座調(diào)節(jié)閥是由381L系列電子式執(zhí)行機(jī)構(gòu)和低流阻直通單座閥組成。該執(zhí)行機(jī)構(gòu)采用一體化的電子控制器模塊，無需另配伺服放大器，且輸出力大；閥體為直通無底蓋上導(dǎo)向“S”流道，閥芯為柱塞型機(jī)構(gòu)，具有流道通暢，流量系數(shù)大等特點(diǎn)。
該產(chǎn)品具有動作可靠，流量特性精度高，可調(diào)比大，結(jié)構(gòu)緊湊，外形尺寸小等優(yōu)點(diǎn)，可廣泛應(yīng)用在石油化工、醫(yī)藥、冶金、造紙、水處理等行業(yè)，控制各種不同流體的介質(zhì)。
DZDLP electronic type electric single-seat control valve is 381L Series electronic actuator and low flow resistance through single-seat valve. The actuator uses an integrated electronic controller module, no need to reprovision the servo amplifier and the output force; body is covered through bottomless oriented “S” flow channel, as the plunger-type valve body with a smooth flow , flow coefficient and so on.
The product has a reliability, flow characteristics and high precision, adjustable ratio, compact structure, small size, etc., can be widely used in petrochemical, pharmaceutical, metallurgy, paper making, water treatment and other industries, control a variety of different fluids the media.
