Level Control Valve with Altitude Pilot FP-450-82

  •  “Always Full” Firewater Reservoir
  •  Ideal for High level reservoirs & water towers
  •  Safer firewater filling
  •  Self operation with No Float
  •  Suitable for horizontal or vertical installation

The BERMAD FP 450-82 Level Control Valve is a hydraulically controlled, diaphragm actuated automatic control valve that shuts at pre-set high reservoir level and opens in response to level drop, keeping the reservoir full. The water level is maintained by the use of a highly accurate pilot valve that precisely senses the water level head from a sensing point at the bottom of the reservoir and controls the main filling valve accordingly. This eliminates the need for the installation of a float mechanism, making it ideal for high level reservoirs.

Typical Product Applications

The Model FP 450-82 senses the static head of the water level in the tank by means of a high sensitivity altitude pilot valve.

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 with the filling and outflow pipes.


In firewater reservoirs, the water level should be kept as constant as possible, with a highly accurate altitude pilot valve the Model FP 450-82 is well suited to fulfill this requirement.

The altitude pilot is highly sensitive to changes and accurately maintains the reservoir water level to within a few centimeters.
