Plastic Float Ball Valve – Auto Water Level Controller 1/2" 3/4"
Plastic Float Ball Valve – Auto Water Level Controller 1/2" 3/4"
Plastic Float Ball Valve – Automatic Water Level Controller
Keep your water tank, water tower, or reservoir at the perfect level automatically — no manual monitoring needed. This durable plastic float ball valve opens and closes based on water level, stopping flow precisely when the set level is reached. Built from tough PA66 nylon and ABS plastic, it handles everyday water management with ease and minimal maintenance.
Key Features
- Automatic Water Level Control: Float-actuated mechanism opens and shuts water flow without any external power source — purely hydraulic operation.
- Dual Port Sizes: Available in 1/2 inch (DN15) and 3/4 inch (DN20) to fit a wide range of standard plumbing connections.
- Male Threaded Connection: Easy, secure installation into tanks, towers, and reservoirs using standard male thread fittings.
- Wide Working Pressure Range: Operates reliably from 0.02 MPa to 1.0 MPa, suitable for both low-pressure and higher-pressure water systems.
- Durable Plastic Construction: Made from PA66 nylon and ABS plastic — lightweight, corrosion-resistant, and long-lasting in wet environments.
- Versatile Applications: Ideal for water tanks, water towers, livestock drinking pools, aquariums, toilets, car wash stations, bathrooms, and more.
- Normal Temperature Media: Designed for use with water at normal temperatures (up to 70°C).

Frequently Asked Questions
Q: What pipe sizes does this plastic float ball valve fit?
A: This float ball valve is available in two port sizes — 1/2 inch (DN15) and 3/4 inch (DN20) — with male threaded connections to match most standard plumbing fittings in water tanks and towers.
Q: Does this float ball valve require electricity or batteries to operate?
A: No. This valve operates purely on hydraulic pressure, using the buoyancy of the float to open and close the valve automatically. There is no need for any electrical connection or external power source.
Q: What is the maximum water pressure this valve can handle?
A: The valve is rated for a working pressure range of 0.02 MPa to 1.0 MPa, making it suitable for both low-pressure gravity-fed tanks and higher-pressure water supply systems.
Q: Is this valve suitable for use with hot water?
A: This valve is designed for normal temperature water applications and can handle media up to 70°C. It is best suited for cold or warm water rather than continuously high-temperature hot water systems.
