FP 450-60 - Level Control Valve
The 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
