A Reduced Diameter Floating Ball Valve is a specialized type of ball valve designed to control flow using a ball with a diameter smaller than the pipeline's diameter. This design is particularly useful for applications where moderate flow control and pressure drop are acceptable, and where space and cost considerations are critical.

Reduced Bore Design: The main characteristic of this valve is its reduced bore, meaning the diameter of the ball is less than the diameter of the pipeline. This design results in a smaller valve size and generally lower material costs.
Floating Ball Mechanism: The ball is not fixed but is held in place by the compression force of the two elastomeric seats, allowing it to float slightly along the axis of the valve. This floating action enables the ball to press against the downstream seat under pressure, ensuring a tight seal.
Compact Size: Due to the reduced bore, these valves are more compact compared to full bore valves, making them suitable for applications with limited space.
Cost-Effective: Using less material in the construction of the valve body and ball makes this type of valve more economical compared to full bore designs.
Economical: Lower material usage translates to cost savings, making these valves an attractive option for budget-conscious projects.
Space-Saving: The compact design is ideal for installations with limited space.
Sufficient Flow Control: Provides adequate control for applications where extreme precision is not necessary.
Versatility: Can be used in a variety of residential, commercial, and light industrial applications.
Water Distribution: Used in residential and commercial plumbing systems for water distribution.
HVAC Systems: Employed in heating, ventilation, and air conditioning systems for regulating water flow.
Light Industrial: Suitable for use in various light industrial applications where moderate flow control is sufficient.
Agricultural: Used in irrigation systems for controlling water flow to fields.
Manufacturing Techniques: These valves are typically manufactured using casting or forging methods. Precision machining is necessary to ensure the valve components fit together properly and function efficiently.
Maintenance Practices: Regular maintenance includes checking for leaks, ensuring the integrity of the seats and seals, and cleaning to prevent buildup that could interfere with the valve’s operation.
