为了便于安装和拆卸螺纹连接的阀门，在管路系统的适当位置上可用管接头。公称通径在50mm以下的阀门可使用管套节作为管接头，管套节的螺纹将连接的两部分连接在一起。

法兰连接的阀门，其安装和拆卸都比较方便。但是比螺纹连接的阀门笨重，相应价格也价高。故它适用于各种通径和压力的管道连接。但是，当温度超过350度时，由于螺栓、垫片和法兰一变松弛，也明显地降低螺栓的负荷，对受力很大的法兰连接可能产生泄漏。
（3）焊接连接阀门
这种连接适用于各种压力和温度，在较荷刻的条件下使用时，比法兰连接更为可靠。但是焊接连接的阀门拆卸和重新安装都比较困难，所以它的使用限于通常能长期可靠地运行，或使用条件荷刻、温度较高的场合。如火力发电站、核能工程、乙烯工程的管道上。
公称通径在50mm以下的焊接阀门通常具有焊接插口来承接荷平面端的管道。由于承插焊接在插口与管道间形成缝隙，因而有可能使缝隙受到某些介质的腐蚀，同时管道的振动会使连接部位疲劳，因此承插焊接的使用受到一定的限制。
在公称直径较大，使用条件荷刻，温度较高的场合，阀体常采用坡口对焊接，同时，对焊接缝有原格要求，必须选用技术过硬的焊工完成此项工作。 DHI-0611
