应用范围:
**应用在航天、船舶重工、**化工、给排水、消防设备、食品**设备、清洗设备、景观喷灌、加湿设备、液压设备、测试设备、水厂等,工作压力在6.4---100MPa的管道系统中。
产品特点:
阀芯均为不锈钢活塞式,活塞环不会被介质中的杂质卡死,动密封性能高,寿命长;活塞与金属阀腔不产生直接摩擦,阀体安装向无限制;**线圈,不易烧毁;长时间停止动作重新启动,动作同样灵敏;启动工作压力0.5MPa。
主要技术参数:
产品规格: | DN0.5~DN200 |
阀体材质: | 不锈钢 |
适用介质: | 水、气、油、蒸汽、**、腐蚀流体等 |
温度范围: | -100~+200℃ |
介质粘度: | 小于50C St(大于时需定制) |
防护性能: | 防水、防爆(Exd IICT5)、防腐 |
接线方式: | 接线座式;引线式;插头式 |
控制方式: | 常开、常闭 |

连接方式: | 内螺纹、法兰(外螺纹和特殊接口可定做或加转接头) |
泄 漏 量: | 零 |
工作原理:
常闭:当线圈通电时,先导阀芯吸合,先导孔打开,阀上腔卸压,活塞靠下腔介质压力推动,电磁阀打开;当线圈断电时,先导阀芯靠弹簧复位,先导孔关闭,阀腔由活塞节流孔增压和复位弹簧的推力,电磁阀关闭。

How it works:
NC: When the coil is energized, the pilot spool pull the pilot hole to open, pressure relief va**e on the chamber, the piston on the lower chamber medium pressure to promote, the electromagnetic va**e is ope**; When the coil power, the pilot va**e by the spring return, pilot hole closed throttle va**e chamber pressurized by the piston return spring and thrust, the electromagnetic va**e is closed.
Normally Open: When the coil is energized, the pilot hole closed, the va**e chamber and pressurized by the piston return spring throttle thrust, the electromagnetic va**e is closed. When the coil power, the pilot va**e by the spring return, pilot hole open, pressure relief va**e on the chamber, the piston on the lower chamber medium pressure to promote the solenoid va**e open.
