Level Control Valve FP 450-80

The Model FP 450-80 Level Control Valve is a hydraulically controlled, diaphragm actuated, control valve that shuts at pre-set reservoir high level and fully opens in response to an approximately one-meter (three-foot) level drop, as sensed by the 3-way altitude pilot mounted on the main valve.

  • Line pressure driven – Independent operation
  • Bi-level altitude pilot
    • No float, simple installation
    • On/Off service
    • Suitable for low quality water
  • Fully supported vulcanized diaphragm
    • Rugged radial seal disk
    • Protected diaphragm
  • Dynamically restrained actuation
    • Non-slam closing
  • Balanced rolling-diaphragm
    • High flow capacity
    • Very low opening & closing ?P requirement
  • External installation
    • Easy access to valve
    • Easy level setting
    • Less wear and tear
  • In-line serviceable – Easy maintenance
  • Flexible design – Easy addition of features

Typical Applications

Bi-Level Water Towers
The Model FP 450-80 senses the static head of the water level in the tank by means of a high sensitivity pilot. To do so accurately, the sensing tube end must be connected to a “still point” at the bottom of the tank. The drainage pipe
provides this “still point”, a location not influenced by flow velocity as in filling and outflow pipes.
