Float Ball valve – Comprehensive Product Guide

Introduction to Float Ball Valves

A float ball valve is a highly reliable and widely used control device designed to automatically regulate the flow of liquid in a tank or pipeline system. It operates by utilizing the buoyancy of a hollow float ball, which rises or falls with the liquid level, opening or closing the valve accordingly. This design eliminates the need for constant manual supervision, making it an ideal choice for water tanks, cooling systems, industrial storage units, and agricultural irrigation.

Float ball valves are valued for their automatic control, corrosion resistance, and durability. They are commonly manufactured from materials such as stainless steel, brass, or engineering plastics, ensuring high strength and long service life.

Product Performance

Float ball valves deliver consistent performance under a wide range of operating conditions. Their key performance characteristics include:

• Automatic Liquid Level Control – The float rises with liquid levels and shuts off the valve once the preset limit is reached, preventing overflow.

• Durability – Made from corrosion-resistant materials, ensuring longevity in water, oil, or mild chemical applications.

• Leak-tight Sealing – Advanced sealing technology ensures zero or minimal leakage during operation.

• Low Maintenance – Simple design with few moving parts reduces the need for frequent servicing.

• Energy Saving – Operates without external power supply, reducing operational costs.

Installation Instructions

Proper installation is crucial for maximizing the efficiency and lifespan of a float ball valve. Follow these guidelines:

1. Preparation

• Inspect the valve and pipeline to ensure they are free of debris.

• Confirm compatibility of valve size, pressure rating, and materials with your system.

2. Installation Position

• Install vertically for water tanks and horizontal tanks.

• Ensure the float has enough clearance to move freely without obstruction.

3. Mounting Steps

• Attach the valve securely to the pipeline connection.

• Position the float arm horizontally for optimal sensitivity.

• Tighten fittings with appropriate torque to avoid leaks.

4. Testing

• Slowly fill the tank and observe the float movement.

• Adjust the float arm if necessary to set the desired liquid level.

• Ensure smooth shut-off when the tank reaches the preset level.

Technical Advantages

Float ball valves stand out from conventional manual and automated valves due to their distinctive technical benefits:

• Automatic Operation – No external power or sensors are required.

• Simple Structure – Fewer components mean reduced risk of malfunction.

• Versatility – Suitable for residential, agricultural, and industrial liquid management.

• High Reliability – Proven performance in continuous operation environments.

• Cost-effectiveness – Low purchase and maintenance cost compared to electronic level controllers.

• Environmental Compliance – Helps reduce water waste by preventing overflow.

Technical Parameters
