1/2" Plastic Water Tank Side Entry Float Ball Valve DN15
1/2" Plastic Water Tank Side Entry Float Ball Valve DN15
Automatic Water Level Control with a Compact Float Ball Valve
Keep your water tank, cistern, or reservoir at the perfect fill level — automatically. This 1/2" (DN15) side-entry hydraulic float ball valve is engineered for simple, reliable, hands-free water level regulation. As the water rises, the buoyant ball floats up and closes the valve; as the level drops, it opens again to refill. No electricity, no sensors — just smart mechanical design. Made in Mainland China.
Key Features
- Automatic Fill Control: Buoyant ball mechanism opens and closes flow based on water level — fully self-regulating.
- Side Entry Design: Mounts directly through the side wall of your tank for a clean, space-saving installation.
- Durable ABS Construction: Corrosion-resistant ABS plastic handles continuous water exposure with ease.
- 1/2" (DN15) Connection: Standard thread size fits most residential and commercial water tanks and cisterns.
- Medium Pressure Rated: Suitable for standard water supply systems and general plumbing applications.
- Wide Temperature Range: Operates reliably between 0°C and 60°C (32°F – 140°F).
- Mini & Compact: Small profile is perfect for tight spaces and smaller storage tanks.
- Manual Control: Simple mechanical operation — no power supply required.
- 1-Year Warranty: Backed by a full one-year manufacturer warranty for peace of mind.

Frequently Asked Questions
Q: What size pipe or fitting does this float ball valve connect to?
A: This float ball valve features a standard 1/2 inch (DN15) threaded connection, making it compatible with the vast majority of residential and light-commercial water tank fittings and plumbing systems.
Q: Is this float valve suitable for outdoor water tanks?
A: Yes. The ABS plastic construction is corrosion-resistant and designed to handle continuous water contact. It operates reliably in temperatures from 0°C to 60°C, making it well-suited for outdoor tanks in mild to moderately warm climates. For freezing environments, additional insulation or a frost-protected setup is recommended.
Q: Does the float ball valve require electricity or any power source to operate?
A: No power source is needed. This is a fully mechanical, hydraulic float valve. The buoyant ball rises and falls with the water level, automatically opening and closing the valve through purely mechanical action — no wiring or batteries required.
Q: How do I install a side-entry float ball valve?
A: Installation is straightforward. Drill or locate the appropriate side-wall fitting hole on your tank, insert the 1/2" threaded inlet through the hole, and secure it with the supplied nut and washer. Connect your water supply line to the inlet, then adjust the float arm angle as needed to set your desired fill level.
