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
