DZDLP型电子式电动单座调节阀是由381L系列电子式执行机构和低流阻直通单座阀组成。该执行机构采用一体化的电子控制器模块，无需另配伺服放大器，且输出力大；阀体为直通无底盖上导向“S”流道，阀芯为柱塞型机构，具有流道通畅，流量系数大等特点。
该产品具有动作可靠，流量特性精度高，可调比大，结构紧凑，外形尺寸小等优点，可广泛应用在石油化工、医药、冶金、造纸、水处理等行业，控制各种不同流体的介质。
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.
