概述

诩嘉自控生产的电动套筒调节阀适用于压差较大且泄漏量稍大的场合,由3810L型(或PSL系列)直行程电子式电动执行机构和套筒调节阀体组成。电动套筒调节阀内含饲服功能,接受统一的4-20mA 或1-5V·DC的标准信号,将电流信号转变成相对应的直线位移,自动的控制调节阀开度,达到对管道内流体的压力、流量、温度、液位等工艺参数的连续调节。 电动套筒调节阀因为其稳定性好、维护简单而广泛应用,可设计成平衡式***了阀瓣上的大部分静态不平衡力,并有一定的阻尼作用,可以减小流体流动引发振动,能用于压差相对较大的场合。 电动套筒调节阀接受调节仪表传来的直流电流信号,控制阀门开度,使被控参数保持在给定值。电动套筒调节阀广泛应用于电力、冶金、化工、石油、轻纺、制药、造纸等工业部门的生产自动化控制。
