| 一般安装信息：真活接旋启式止回阀设计用于水平安装，但是也可以安装在垂直朝上的管道上。安装止回阀必须使阀门上的流向箭头指向流体介质流动的方向。不要朝下安装阀门。流体流速不能超过5英尺/秒。最小开启压力不低于0.5
psi。 General Installation Information: True Union Swing check valves are designed for horizontal installations, but may be installed in up-flow only vertical position. Check valves MUST be installed with the valves FLOW arrow pointing in the direction of the flow. Do not install valve upside down. Flow velocity should not exceed 5ft./sec. Minimum opening pressure less than 0.5 psi. |
