Pegler Polyball Float 4 1/2 inch
(float Ball) 

Product: 4½" Polyball (Float Ball)
Material: Usually made from durable, lightweight plastic such as polyethylene or polypropylene
Diameter: 4.5 inches (approx. 114 mm)
Construction: Seamless or welded hollow sphere, air-filled for buoyancy
Color: Commonly black, blue, or natural (varies by manufacturer)

Key Features:

Buoyant: Designed to float on liquid surfaces
Chemical-resistant: Suitable for water, wastewater, and some chemicals
Lightweight yet durable: Resistant to corrosion, rust, and UV (depending on grade)
Smooth surface: Helps prevent buildup and ensures consistent movement

Common Uses:

Float valves in tanks and cisterns
Level control systems in water storage
Agricultural and irrigation setups
Industrial liquid level regulation
Septic or wastewater systems

How it works:
The polyball rises and falls with the liquid level. When connected to a float valve, it helps automatically open or close the valve to maintain a set fluid level.
