CKD数字式减压阀端盖和缸筒连接使用可密封部能搭载小型各种标准T型开关，安装开关后也能实现节省空间端盖和缸筒都为银色产品明亮美观喜开理数字式电空减压阀基本特点 EVR-2500-28-E2-S1B字节LED3位、显示精度2％满刻度以下30V以下50mA以下，电压降2.4V以下、PLC继电器对应输入信号为0％时，有1％满刻度以下残余压力。
CKD数字式减压阀一般采用水平安装，由阀后压力进行控制。当压力感应器检测到阀门压力指示升高时，减压阀阀门开度减小；当检测到减压阀后压力减小，减压阀阀门开度增大，以满足控制要求。
日本CKD是日本CKD株式会社投资的气动公司，主要制造气源处理三大件、气缸、电磁阀等自动化产品。
CKD主要生产的产品有自动化机械（灯管制造，CCFL,LED制造设备，药品泡壳包装设备，二次电池卷绕机，三维焊锡印刷基板检查仪）；气动控制系统（FRL气源处理件，气动换向阀，气缸以及其他附件）；流体控制系统（多介质电磁阀，气控阀，马达阀，分析仪器阀，切削液控制阀，高真空阀，煤气天然气LPG阀，高纯化学液体阀，工艺气体阀）以及省力系统（DD-MOTOR,间隙式转台）。在2001年日本CKD株式会社在上海成立负责销售的喜开理（上海）机器有限公司，并在无锡建立大型生产日本CKD产品已经广泛的应用在电子、模具、轻工机械、实验室、半导体设备、化工机械、自动化设备等行业。
CKD电磁阀选型资料参考：
1、根据管道参数选择电磁阀的：通径规格(即DN)、接口方式
1)按照现场管道内径尺寸或流量要求来确定通径(DN)尺寸;
2)接口方式，一般>DN50要选择法兰接口，≤DN50则可根据用户需要自由选择。
2、根据流体参数选择电磁阀的材质、温度组
1)腐蚀性流体：宜选用耐腐蚀电磁阀和全不锈钢;食用超净流体：宜选用食品级不锈钢材质电磁阀;
2)高温流体：要选择采用耐高温的电工材料和密封材料制造的电磁阀，而且要选择活塞式结构类型的;
3)流体状态：大至有气态，液态或混合状态，特别是口径大于DN25时一定要区分开来;
4)流体粘度：通常在50cSt以下可任意选择，若超过此值，则要选用高粘度电磁阀。
3、根据压力参数选择电磁阀的原理和结构品种
