4.2手动操作阀门当手柄和阀杆顶端的位置标示沟槽平行于阀门通道时，阀门打开，垂直于阀门通道时阀门关闭。
4.3气动或电动操作阀门的打开或关闭，由阀门气动装置或阀门电动装置上的位置指示器来标示。
4.4气动阀门的阀门气动装置和电动阀门的电动装置的工作原理及操作说明见相关的气动装置和电动装置说明书。
5 储存、保养、安装、适用及维修
5.1 储存及保养
5.1.1 阀门两端应堵塞，防止尘埃、污物等侵入。
5.1.2 阀门应存放在干燥、通风的室内。
5.1.3 长期存放的阀门应定期检查，清除污垢，并在加工面上涂防锈油。
5.2 安装
5.2.1 安装前应对阀门进行仔细检查，主要检查项目有：
a、检查阀门内腔，特别是检查密封面是否有污物粘污，并检查密封面有否损坏。
b、检查阀杆填料压紧是否合适，应确保填料密封，但有不妨碍阀
杆灵活转动 。
5.2.2 安装时应仔细核对阀门标志是否与使用要求相一致。
5.2.3阀门安装后应检查连接螺栓是否均匀拧紧。
5.2.4 阀门安装的位置应注意操作和维修的便利。
5.2.5 阀门安装后，在系统或管路试压时，应处于全开位置。
5.3 使用
5.3.1 使用中，阀门应全开或全关，不允许部分开启作调节流量用。
5.3.2 手动开启或关闭阀门时，操作人员应注意操作位置和握住手柄的方式，以免启闭件上流体速度分布极不一致、启闭件上的压力产生一个很大的关闭扭距，使阀门快速关闭，手柄突然冲向关闭位置，而引起对操作人员的伤害。
5.3.3手动操作阀门的操作手柄按操作阀门所需开关力距进行设计、制造，用户不得借助辅助杠杆或其它工具来加大开关力距。
5.4 维修
5.4.1 使用中的阀门应定期进行检查、维修，主要项目有：
a、检查密封面的磨损情况。如有损坏，应进行修复或更换。
b、检查垫片、填料有否损坏或失效。如有损坏或失效应及时更换。但不应在带压的情况下更换填料。
c、检查各连接螺栓是否拧紧，手柄连接是否正常。
5.4.2 阀门解体检修装配之后，应进行密封性能试验。试验应按有关标准要求进行，并作详细记录，以备查考。
5.5气动阀门的阀门气动装置和电动阀门的电动装置的储存、保养、安装、使用和维修，详见阀门气动装置和电动装置说明书。
