A brass ball valve is a type of quarter-turn valve that uses a hollow, perforated, and pivoting ball to control the flow of a fluid (typically a liquid or gas) through a pipe or tubing. It is called a "brass" ball valve because the main body of the valve is typically made from brass, which is a corrosion-resistant alloy of copper and zinc. The ball inside the valve has a hole (bore) through its center, and when the handle of the valve is turned 90 degrees, the bore is either aligned with the flow of the fluid, allowing it to pass through (open position), or perpendicular to the flow, blocking the fluid (closed position).
Brass ball valves are widely used in various applications due to their durability, reliability, and ease of operation. They are commonly found in plumbing systems, industrial processes, HVAC (Heating, Ventilation, and Air Conditioning) systems, and many other fluid control applications. These valves are known for their tight sealing, minimal pressure drop, and resistance to corrosion, making them suitable for a wide range of environments and fluid types. They are available in various sizes, from small residential valves to large industrial ones, to accommodate different flow rates and pressure requirements.
Brass ball valves come in various types to suit different applications and needs. Here are some common types of brass ball valves:
In a full port ball valve, the bore through the ball is the same size as the pipe, allowing for minimal flow restriction. This type is suitable for applications where minimal pressure drop is important.
In standard port ball valves, the bore size is smaller than the pipe size. While these valves may cause slightly more pressure drop than full port valves, they are often used in applications where the size and weight of the valve are a concern.
Three-way ball valves have three openings in the ball and can be used to divert or mix the flow of fluids. They are commonly used in applications where the direction of flow needs to be controlled or switched.
Mini ball valves are compact and typically used in applications with limited space, such as in small plumbing systems or for shut-off valves in appliances.
Multi-port ball valves have multiple outlets and inlets, allowing for complex flow configurations. They are used in applications where flow direction and distribution need to be precisely controlled.
Vented ball valves have a small hole that allows pressure or trapped gas to be released from the valve cavity. They are often used in applications where pressure relief is necessary.
Lockable ball valves come with a mechanism to secure the valve in an open or closed position, preventing unauthorized operation.
Flanged ball valves have flanges on the valve body, making them suitable for applications that require bolting the valve to a pipe or other equipment.
Threaded ball valves have female or male threads for easy installation in threaded piping systems.
Sweat ball valves are designed for use in copper pipe systems, where they can be soldered directly to the pipes.
Compression ball valves are used in plastic pipe systems and are installed using compression fittings.
While not made of pure brass, bronze ball valves are commonly used in marine and seawater applications due to their corrosion resistance.
The choice of the type of brass ball valve depends on the specific application and the requirements of the plumbing or fluid control system.
