一、概述 Outline
DZDLP型電子式電動單座調節閥是由381L系列電子式執行機構和低流阻直通單座閥組成。該執行機構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向“S”流道，閥芯為柱塞型機構，具有流道通暢，流量系數大等特點。
該產品具有動作可靠，流量特性精度高，可調比大，結構緊湊，外形尺寸小等優點，可廣泛應用在石油化工、醫藥、冶金、造紙、水處理等行業，控制各種不同流體的介質。
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, 免費信息pact 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.
