阀门功能
VALVE FUNCTION

• 电动操作开启/关闭阀门
  Electrically operated ON/OFF (OPEN/CLOSED) valve
• 反应快速的高效控制
  High capacity controls for fast response
• 在电磁阀激发前，主阀处于开启位置
  Main valve is in the open position until solenoid is energized
• 当主阀隔膜出现故障，‘R’方向上的主阀流体将主动关闭
  Main valve flows in the 'R' direction for positive closure upon main valve diaphragm failure
• 主阀配置防锈阀杆
  Main valve is equipped with anti-scale stem
• 限制开关阀杆可作为位置指示器
  Limit Switch stem serves as a position indicator
• 当阀门重置时，所提供的压力表显示型号22-1盖压。

FS99流量感应器
FS99 Flow Sensor

　　FS99流量感应器的不锈钢感应探头应该由安装承包商根据排泄管所要求的长度来确定所要切割的探头长度。用户要配置实际安装三通。如图所示，FS99安装在水平位置。如果采用流量开关、浮动开关，或其他类型的感应器，请咨询美国瓦茨，了解兼容性。
　　The FS99 Flow Sensor SS probes should be cut to length to fit within drain pipe requirements by the installation contractor. Client to furnish the actual installation tee. The FS99 is to be installed in a horizontal position, as shown. If a Flow Switch, Float Switch, or other type of sensor is used, please contact Watts for compatibility.

注：用户提供安装三通
