Brass Ball Valves
Explore Tameson’s wide range of 2-way brass ball valves from various global manufacturers. A 2-way brass ball valve is one of the most common valves in the market. The valve has a brass housing, two ports (an inlet and an outlet), and a ball with a bore. They are operated by a manual hand lever to turn the ball 90 degrees, so they are also called quarter-turn ball valves or shut-off valves. When the handle direction is parallel to the connecting pipe or hose, the ball valve opens, allowing media to flow from the inlet through the bore to the outlet. When the handle direction is perpendicular to the connecting pipe or hose, the valve is closed, obstructing the media flow through the valve. This allows for easy visual identification on whether a two-way ball valve is open or closed.
The brass housing and simple design of 2-way ball valves make them very common due to their easy operation, reliability, long service life, and wide range of applications. Brass is an alloy of copper and zinc and has great mechanical properties. These ball valves are durable, with minimal leakage over their lifespan, even if they have not been used for a long period of time. 2-way brass ball valves can be used with drinking water, gas, mineral oils, compressed air, and many other non-aggressive media. But they are not suitable for use with salt water or distilled water due to the risk of dezincification. Dezincification reduces the mechanical strength of brass by causing the zinc to be removed from the alloy resulting in a porous structure. However, brass ball valves are more resistant to contaminated media than other housing materials and provide reliable sealing even in the case of dirty media. They can withstand high pressure, high temperature, and high flow rates. They are also economical due to their simple and robust design, low cost, and low maintenance needs. Due to these advantages, brass ball valves are used in many residential and industrial applications. 2-way brass ball valves commonly have water or gas approvals, and they are easy to install due to their threaded connection.
