Level Control Valve with Bi-Level Electric Float FP-450-65


  • Reservoir filling
-Very low supply pressure -Low noise generation -Energy cost critical systems -Systems with poor water quality The Model FP 450-65 Level Control Valve with Bi-Level Electric Float is a hydraulically operated, diaphragm actuated, control valve that controls reservoir filling in response to an electric float switch signal. The valve fully opens at a pre-set low level and closes at a pre-set high level.

Typical Product Applications

Infrastructure Installation
Reservoirs vary in their characteristics – location, elevation, filling and emptying flow and pressure, surface area, etc. These various characteristics require various level control valve solutions.
The Model FP 450-65 is the ideal solution for level control in reservoirs – shallow and deep, low and high elevation, rooftop and basement, in water towers, and wherever electric power is available. Model-FP-450-65_1

Rooftop Reservoirs
Rooftop reservoir level control is attained by electric control of the basement pumps according to reservoir level. As overflow of a rooftop reservoir can cause costly damage, additional backup protection is recommended. The Model FP 450-65 is suited to this
function. When open, it presents minimal interference, but when needed, it shuts off securely.
To ensure supply pressure to upper floor consumers or the fire protection system, install the Model FP 420 or 42T Pressure Control Valve upstream from the Model FP 450-65.
