The Model FP 450-66 is a float controlled valve equipped with a 4-way, “last position”, bi-level float pilot assembly.
The float [1] slides along the rod [2]. When the float reaches either the adjustable high [3] or low [4] level stoppers, it

adjustable stoppers, the main valve remains in its last position.
在高水位时，浮球导阀使压力进入控制腔[6]，主阀关闭。
At high level, the float pilot applies pressure to the control chamber [6], powerfully shutting off the main valve.
在低水位时，浮球导阀使控制腔压力排出，主阀开启。
At low level, the float pilot vents the control chamber, powerfully opening the main valve.
对于 8”及更大尺寸的阀门，增配加速器[7]可以加快阀门反应速度。
For 8” valves and larger, an accelerator [7] quickens valve response.
