The Model FP 450-67 Level Control is a hydraulically controlled, diaphragm actuated valve for controlling the level in firewater reservoirs.
The 2 way vertical float modulates the valve to keep the reservoir full or at a preset level at all times.
The unobstructed flow passage, simplicity of design and robust construction makes the FP 450-67 suitable for use with firewater which is often of a poor quality.
