平衡閥是一種特殊功能的閥門，有定量的測量功能和調節功能，系統調試時，調試人員通過與專用智能儀表人機對話，對平衡閥進行調整，即可實現系統的水力平衡。它具有良好的流量調節特性，相對流量與相對開度呈線性關系。有精確的閥門開度指示，最小讀數為閥門全開度的1℅。有可靠的開度鎖定記憶裝置，閥門開度變動后可恢復至原鎖定位置。有截止功能，安裝了平衡閥就不必再安裝截止閥。

平衡閥的原理是閥體內的反調節，當入口處壓力加大時，自動減小通徑，減少流量的變化，反之亦然。如果反接，這套調節系統就不起作用。而且起調節作用的閥片，是有方向性的，反向的壓力甚至可以減少甚至封閉流量。既然安裝平衡閥是為了更好的供暖，就不存在反裝的問題。如果是反裝，就是人為的錯誤，當然就會糾正。平衡閥屬于調節閥范疇，它的工作原理是通過改變閥芯與閥座的間隙（即開度），改變流體流經閥門的流通阻力，達到調節流量的目的。
