FP 450-60 - Level Control Valve

FP_450-60_Big_GalleryThe Model FP 450-60 Level Control Valve with Modulating Horizontal Float is a hydraulically controlled, diaphragm actuated, control valve that controls reservoir filling to maintain constant water level, regardless of fluctuating demand.

 

Features and Benefits

  • Line pressure driven – Independent operation
  • Modulating hydraulic float control
    • “Always Full” reservoir
  • Fully supported vulcanized diaphragm
    • One moving part
    • Rugged radial seal disk
    • Protected diaphragm
  • Dynamically restrained actuation
    • Moderate valve reaction
    • Non-slam closing
  • Balanced rolling-diaphragm
    • High flow capacity
    • Very low opening and closing pressure requirements
  • In-line serviceable – Easy maintenance
  • Flexible design – Easy addition of features
  • External installation – Pilot operated

 

Typical Applications

Large Fire Water Reservoirs

Mechanical level control valves present various issues:

  • Valves are often at inaccessible locations
  • Float and arm assemblies are heavy and cumbersome
  • Relatively low maximum pressure
  • Tendency for mechanical devices to leak
  • Increased valve corrosion due to humid environment inside the tank
  • Difficult maintenance

The Model FP 450-60 overcomes these difficulties by applying a float pilot, separated from the the valve itself, which controls a Hydraulic Valve.

Consider replacing the “60” horizontal float assembly with the “67” vertical float assembly for:

  • Heavy duty service
  • Easy level setting
  • Aggressive or corrosive fluids
