Automatic Float Ball Valve Water Level Controller – 2-Pack

Automatic Float Ball Valve Water Level Controller — 2-Pack

Keep your water tank, pool, or water tower at the perfect level — automatically. This 2-pack of plastic float ball valves provides hands-free water level management for residential and commercial applications. No electricity required, no complicated setup — just reliable, self-regulating water control that saves water and effort.

Why Choose This Float Valve?

• Fully Automatic Operation: When water levels drop, the float sinks and opens the valve; when full, it rises and shuts off flow — completely hands-free.
• No Electricity Needed: Operates purely on water pressure (1–10 KG / 0.1–1 MPa), making it ideal for solar-powered systems, remote tanks, and off-grid setups.
• Four Intake Ports: High-volume water intake for faster refill times in large tanks and pools.
• Compact & Lightweight Design: Small footprint (100.2 × 58 × 50 mm) fits easily into tight spaces without sacrificing performance.
• Long Service Life: Durable plastic construction withstands temperatures up to 120°C in high-resistance applications, with minimal maintenance required.
• Easy Installation: Simple upright inner-installation design; no special tools needed. Ideal for DIY and professional installs alike.
• Water-Saving: Automatically stops flow when the tank is full, helping conserve water and reduce waste.

Installation Tips

• The float must be positioned vertically during installation.
• For top-entry installations, use an elbow fitting to connect the float valve to the inlet line.
• Secure the feed line horizontally first, then connect the control valve at the water inlet.
• The main inlet diameter should match the control valve's nominal diameter.
• Always fully open the globe valve when in use.
• If installing two valves in the same pool or tank, ensure both are set at the same horizontal level.
• Before installation, flush the pipes to remove any debris or impurities that could block the valve.
• In areas with lower water quality, periodic maintenance will keep valves performing optimally.

Frequently Asked Questions

Q: What types of tanks or systems are these float ball valves compatible with?

A: These automatic float valves are suitable for a wide range of applications including residential water storage tanks, agricultural water towers, swimming pools, solar water systems, and commercial cisterns. They work with any clean-water system operating within a pressure range of 0.1–1 MPa (1–10 KG).

Q: Do these valves require electricity to operate?

A: No — these float ball valves are entirely mechanical and require no electricity. They operate using the natural buoyancy of the float and the incoming water pressure to automatically open and close the valve, making them perfect for off-grid, solar-powered, and remote water storage systems.

Q: How do I install the float valve if my inlet is at the top of the tank?

A: For top-entry installations, you will need an elbow fitting (not included) to redirect the connection so the float valve hangs correctly in a vertical orientation inside the tank. Secure the horizontal feed line first, then attach the float valve at the water inlet point.

Q: Can I use two valves in the same pool or tank at the same time?

A: Yes. When using two valves simultaneously in the same pool or tank, make sure both valves are mounted at exactly the same horizontal level so they activate and deactivate at the same water level, ensuring balanced and consistent water control.
