DCS Series dry quick connector

DCS Series dry quick connector
The DCS STANAG 3756 dry quick connector is designed specifically for the safe, fast, and leak-free connection and disconnection of fluid pipelines. Originally developed for military applications to enable rapid fuel supply to aircraft, vehicles, and ground equipment, its outstanding performance has since led to widespread adoption in civilian sectors. Today, it is extensively used in industries such as chemicals, food processing, new energy liquid fuels, and offshore platforms—wherever high levels of safety and reliability are required.

The main characteristics of DCS dry joints are:

Bidirectional self sealing design: When the joint is connected and disconnected, both ends of the valve will automatically close, achieving no leakage.

High reliability and durability:Made of high-strength and corrosion-resistant materials, thickened and wear-resistant materials are used at the positions of the rotary joint and valve disc guide plate

Optimization for specific media:The SOTUS dry joint product line is very rich, with specialized designs and optimizations for different media such as chemicals, petroleum products, liquefied gases, etc

清晰的状态指示:一些产品具有清晰的连接和断开状态指示,方便操作人员判断

易于维护: 模块化设计,快速更换,化繁为简,高效运行保障

卓越兼容性:可以和主流的TODO、MannTek、Flexotech品牌同类产品相互连接。

技术参数:

尺寸:1” (DN25) - 6” (DN100)

工作压力:最高25bar

测试压力: 工作压力 +50%

材质:铝合金 、不锈钢、镍基耐蚀合金

密封:氟橡胶、三元乙丙橡胶、全氟醚橡胶

末端连接:NPT / BSP / PN25/40 / ANSI 150 /300

工作原理:

将母头端插入公头端后,顺时针转动15°,公母头之间就位并形成密封,这个角度下公母头各自的阀瓣还处于关闭状态,再旋转90°的过程中,阀瓣开启并逐渐抵达最大开度位置。

断开接头的方式是通过逆时针转动105°来实现。

符合EN 13480 金属工业管道标准

符合欧盟压力设备指令 2014/68/EU(PED)安全要求
