- “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.

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.
