Brass Flange Float Ball Valve for Liquid Level Control A brass flange float ball valve is a highly efficient and reliable device designed for automatic liquid level control in tanks, reservoirs, and other storage systems. This type of valve operates based on the principle of buoyancy, utilizing a float mechanism to regulate the flow of liquids without requiring external power or manual intervention. Design and Construction The valve is primarily constructed from brass, a durable and corrosion-resistant material suitable for various liquid applications, including water, oil, and mild chemicals. The brass body ensures longevity and resistance to wear, even in demanding environments. The flange connection allows for secure and leak-proof installation, making it ideal for high-pressure systems. The key components include: 1. Float Ball – A hollow, buoyant sphere that rises and falls with the liquid level, actuating the valve mechanism. 2. Lever Arm – Connects the float to the valve, translating vertical movement into rotational action. 3. Valve Seat and Seal – Ensures a tight shut-off when the liquid reaches the desired level, preventing overflow or underflow. 4. Flanged Ends – Facilitates easy installation and maintenance by bolting directly to pipeline flanges. Working Principle The float ball moves with the liquid level. As the liquid rises, the float lifts, pulling the lever arm to close the valve and stop inflow. Conversely, when the liquid level drops, the float descends, opening the valve to allow more liquid in. This automatic operation ensures consistent liquid levels without manual adjustments. Applications Brass flange float ball valves are widely used in: - Water storage tanks (residential, industrial, and agricultural) - Boiler feed systems - Cooling towers - Fuel storage and dispensing systems - Chemical processing tanks Advantages - Durability – Brass construction resists corrosion and high pressures. - Automatic Operation – No need for electrical power or manual control. - Leak-Proof Design – Flanged connections ensure a secure seal. - Low Maintenance – Simple mechanism with minimal moving parts reduces wear. - Versatility – Compatible with various liquids and temperatures. Conclusion The brass flange float ball valve is an essential component for efficient liquid level management. Its robust design, automatic functionality, and ease of installation make it a preferred choice across multiple industries. Whether for water supply, fuel control, or industrial processes, this valve ensures reliable performance and long-term cost savings.
