湖北威格士带位置反馈比例换向阀KBFG5V-7-33C160N-EX-M2-PH7-H1-11威格士方向控制阀阀宜水平安装。水平安装时，阀盖宜向上。消防给水系统的减压阀阀后应有排水设施。自动喷水灭火系统的需减压时，减压阀应设置在报警阀前(沿水流方向)，与单个报警阀配套设置的减压阀，可不设备用减压阀；与多个报警阀配套设置的减压阀，应设备厂用减压阀。用于热水供应工程的减压阀，应采用热水型减压阀。 

采用干管干管循环方式(半循环方式)的热水供应工程，减压阀设置要求应与冷水工程相同；采用立管循环方式(全循环方式)的热水供应工程，减压阀设置应防止热水循环的破坏，各分区回水管在汇合点压力应平衡。 威格士方向控制阀的变化工作原理
