压力和差异释放控制器由阀门和压力执行器组成。主要用于限制压力（A）或差压力（PA）
在系统/变电站/泵上。
控制器通常是关闭的：由于弹簧伸展的弹簧，AV（P）A构成正常闭合的阀门和AF（P）A。
压力和差压力减压控制器主要安装到旁路中。如果连接完全关闭，它们可用于使热量分布到其他网络连接或闲置流。
如果流动降至最低泵容量，压力和差压力释放控制器可以保护可变流动泵免受过载。它们可以减轻泵/施用，并将加热动力转发到其他连接。
也可以将压力控制器安装到返回中，以维持系统中更高的（静态）压力。
功能和好处
释放泵/应用和向其他连接的转发加热动力
为苛刻的系统制造，耐腐蚀，气蚀和污垢
连接系统受到保护，免受压力飙升，波动，气蚀和噪声
