Collection:Mini Ball Valves

Explore Tameson’s wide range of 2-way brass mini ball valves from various global manufacturers. A mini ball valve is suitable for applications with limited installation space. These ball valves save space, weight, and money. The 2-way function means it has two ports, an inlet and an outlet, and a ball with a bore in it. A 2-way mini ball valve can be operated by turning the handle by 90 degrees, so they are also called quarter-turn valves. The handle is connected directly to the ball through the stem. When the handle direction is parallel to the connecting pipe or hose, the ball valve opens and allows 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 of whether a two-way brass mini-ball valve is open or closed. Manual ball valves are one of the most common valves due to their simple operation, reliability, long service life, and wide range of applications.

The brass housing makes these mini ball valves suitable for a wide variety of media, such as water, neutral, gaseous, and non-aggressive, liquid media, mineral oils, and compressed air. Some of the valves from the selection are suitable for vacuum. Brass is an alloy of copper and zinc and has great mechanical properties. These ball valves are durable, with very less leakage over their lifespan, even if they have not been used for a long period of time. 2-way brass mini 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 compared to other types of housing material 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. Certain mini-ball valves come with approvals like DIN EN 331 for gas applications. The brass housing also makes them economical and able to withstand high pressure, high temperature, and high flow rate applications. The threaded connection ports enable easy installation. Manual 2-way brass mini ball valves are known for their small size, simple operation, reliability, long service life, and wide range of applications. They are available in a wide range of thread standards and sizes.
