文档介绍：普通型 KFD 系列
Common type KFD series
一、概述 Brief introduction
该系列电动阀门控制箱,是与我厂生产的ZW型、JQ 型及QW 型阀门电动装置配套使用的电控箱,用于控制阀门的开启和关闭,可用于现场单独控制或远方集中控制。
KFD型电控箱有抽屉式和挂壁式两种结构。
This series of control of electric valve is the one to be used together with ZW type, JQ type and QW type electric valve actuator produced by pany and to control the opening and closing of valve. It can be used in site individual control or long-distance centralized control.
KFD type electric control has two kinds of structure: drawer type and wall type.
