When it comes to ensuring smooth and reliable fluid control, choosing the right valve is critical. Among various valve types, the Floating Ball Valve stands out for its versatility, durability, and sealing performance. As someone who has worked in the industrial equipment sector for years, I understand how vital it is to select components that guarantee both safety and efficiency. Manufactured with precision and quality materials, Zhejiang Liangyi Valve Co., Ltd. offers a range of Floating Ball Valves designed to meet diverse application requirements.
A Floating Ball Valve is a type of quarter-turn valve that uses a floating ball to control the flow of liquids or gases. Unlike fixed or trunnion-mounted ball valves, the ball in this design is not rigidly held in place but is allowed to "float" slightly downstream under pressure. This floating motion helps press the ball firmly against the downstream seat, creating an effective seal even at low operating pressures.
The Floating Ball Valve functions primarily to start, stop, and regulate fluid flow. When the valve handle is turned 90 degrees, the ball rotates to open or close the passage. Its sealing performance depends on the pressure of the medium pushing the ball against the seat ring.
Key benefits of this valve include:
Excellent tightness even under low pressure.
Simple structure with minimal maintenance.
Compact and lightweight design for easy installation.
Quick on-off operation for time-efficient control.

All valves from Zhejiang Liangyi Valve Co., Ltd. undergo strict quality inspections and pressure testing to ensure optimal performance in every environment—from chemical processing to water treatment and oil pipelines.
The Floating Ball Valve design ensures that the ball remains self-centering under pressure. This reduces seat wear and extends service life. Moreover, its simple structure allows for easy disassembly and maintenance, reducing downtime in production operations. I personally prefer this valve type in high-cycle applications because it combines reliability with cost-effectiveness.
The importance of Floating Ball Valves lies in their tight shut-off capabilities and broad media compatibility. They can handle gases, oils, steam, and even corrosive chemicals, making them ideal for industries such as petrochemical, power generation, food processing, and water supply systems. The valve's floating mechanism ensures consistent sealing without complex adjustments, even after prolonged use.
Floating Ball Valves are widely applied in:
Oil and Gas Pipelines
Petrochemical Plants
HVAC and Water Systems
Marine and Offshore Installations
Power and Energy Industries
The versatility of this valve makes it suitable for both manual and automated systems, offering compatibility with electric or pneumatic actuators.
A1: The key difference lies in the ball's support mechanism. A Floating Ball Valve has a freely suspended ball that moves slightly downstream to ensure sealing, ideal for smaller sizes and lower pressures. A trunnion-mounted ball valve, on the other hand, uses fixed supports for high-pressure applications.
A2: As an engineer who has used Liangyi's products in multiple projects, I can confidently say their Floating Ball Valves stand out for their durability, tight sealing, and corrosion resistance. The company uses premium stainless steel and advanced machining to guarantee precise performance across all models.
A3: Maintenance is simple. Regularly check for wear on the seals and lubricate the stem if necessary. Make sure to operate the valve periodically to prevent sticking. Valves from Zhejiang Liangyi Valve Co., Ltd. are designed for easy maintenance, allowing you to replace parts quickly without specialized tools.
Having worked with various valve manufacturers, I find Zhejiang Liangyi Valve Co., Ltd. to be a reliable partner. Their strict quality control, competitive pricing, and customized solutions make them one of the top valve suppliers in China. Every Floating Ball Valve they produce reflects professional craftsmanship and a commitment to safety and performance.
If you're looking for a valve that combines excellent sealing, easy operation, and durability, the Floating Ball Valve is a perfect choice. It's a cost-effective solution for ensuring stable and reliable flow control in any industrial system.
