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

  • One-piece molded elastomeric moving part –
    No maintenance required
  • Dynamically restrained actuation

-Non-slam closing

  • Balanced rolling-diaphragm

-High flow capacity
-Very low opening & closing pressure 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.
