电站截止阀适用于火力电站各种系统的管路上，切断或接通管路介质。适用介质：水、蒸汽等非腐蚀性介质。电站阀门与其他阀门产品相比的特点是高温高压，独特的自密封设计，压力越高，密封越可靠。由于性能技术特性、工况的特殊使产品也形成了其他产品所替代不了的特点。

a、启闭无摩擦。这一功能完全解决了传统阀门因密封面之间相互摩擦而影响密封的问题。
b、上装式结构。对装在管道上的阀门可直接在线检查与维修，能有效减少装置停车，降低成本，
C、单阀座设计。消除了阀门中腔介质因异常升压而影响使用安全的问题。
d、低扭矩设计。特殊结构设计的阀杆，只需配一个小手把阀门就能轻松启闭。
e、樑形密封结构。阀门是靠阀杆提供的机械力，将球樱压到阀座上而密封，使阀门的密封性不受管线压差变化的影响，在各种工况下密封性能都有可靠保证。

f、密封面的自清洁结构。当球体倾离阀座时，管线中的流体沿球体密封面成360度均匀通过，不仅消除了高速流体对阀座局部的冲刷，也冲走了密封面上的聚积物，达到自清洁的目的。

电站止回阀：止回阀又称单向阀或逆止阀，其作用是防止管路中的介质倒流。也属千止回阀类。启闭件靠介质流动和力量自行开启或关闭，以防止介质倒流的阀门叫止回阀。止回阀属于自动阀类，主要用干介质单向流动的管道上，只允许介质一个方向流动，以防止发生事故。电站止回阀的安装应注意以下事项：

a、在管线中不要使止回阀承受质星，大型的止回阀应独立支撑，使之不受管系产生的压力的影响。
b、安装时注意介质流动的方向应与阀体所栗箭头方向一致。
C、升降式垂直瓣止回阀应安装在垂直管道上。
d、升降式水平瓣止回阀应安装在水平管道上。
