因此，可以避免使用回流管。它安装在先导控制阀（2）和方向阀（16）之间。阻尼程度（减压冲击）由喷嘴（18）的尺寸决定。喷嘴Ø1.2mm（订购代码..R12..）建议使用。带开关减震（夹芯板）的减压阀，“DBW…/…S6E…R12”型通过开关减震阀（17）延迟从B2到B1的连接打开。压力峰值和声减压冲击的表示：方向阀打开减压阀| DB；DBW 7/22 RE 25802，版本：2021至2020年，博世力士乐股份公司一般尺寸NG10 NG16 NG25“DB..20”NG25“DB..25”NG32重量▶ 底板安装–DB…kg 2.6–3.5–4.4–DBW…kg 4.05–4.95–5.85–DBC…kg 1.2–DBWC…kg 2.65–DBC10或30。。。千克1.5–DBWC 10或30。。。千克2.95▶ 螺纹连接–DB…G kg 5.3 5.2 5.1 5.0 4.8–DBW…G kg 6.75 6.65 6.55 6.45 6.25安装位置任何环境温度范围▶ DB…°C–20…+80（NBR密封）–15…+80（FKM密封）▶ DBW…°C–20+50（NBR密封）–15…+50（FKM密封）符合性▶ CE符合低压指令2014/35/EU，根据EN 60204-1:2006-01和DIN VDE 0580进行测试，归类为部件液压大工作压力▶ 端口P，X杆350▶ 端口T bar 315大背压▶ 端口Y（DB）bar 315▶ 端口Y，T（DBW）bar 210，带直流电磁阀160，带交流电磁阀大整定压力bar 50；100; 200; 315; 350小设定压力流量取决于（见9页的特性曲线）大流量▶ 底板安装长度/分钟250–500–650▶ 螺纹连接l/min 250 500 500 650液压油见表88页液压油温度范围°C–20…+80（NBR密封）-15…+80（FKM密封）粘度范围mm2/s 10…800液压油的大容许污染度，清洁度等级符合ISO 4406（c）等级20/18/15 1）技术数据（对于超出这些值的应用，请咨询我们！）注意事项：▶ 油箱预加载会增加小设定压力（端口T和Y）▶ 定向阀座阀的技术数据见数据表22058，定向滑阀数据表23178。▶ 型式检验试验安全阀的偏差技术数据见17页。1） 液压系统中必须遵守部件规定的清洁度等级。有效过滤可防止故障，同时延长部件的使用寿命。

return line can thus be avoided. It is installed between the pilot control valve (2) and the directional valve (16). The degree of damping (decompression shock) is determined by the size of the nozzle (18). Nozzle Ø 1.2mm (ordering code ..R12..) is recommended. Pressure relief valve with switching shock damping (sandwich plate), version "DBW…/..S6E...R12" The opening of the connection from B2 to B1 is delayed by means of the switching shock damping valve (17).
