Ball Valves With Drinking Water Certificates

Explore Tameson’s wide range of manual 2-way brass ball valves with drinking water approval from various global manufacturers. A drinking water ball valve adheres to drinking water standards (i.e. KTW, DVGW, NSF, etc.), making it suitable and safe for drinking water applications. This ensures that the water ball valve is suitable and safe for drinking water applications. The design of these valves prevents the stagnation of water in the hollow spaces around the ball. As a result, the risk of bacteria growth, such as Legionella, is greatly reduced. Additionally, the construction reduces the risk of frost damage during winter. 2-way water ball valves are made to keep the water upstream safe when closed. A common application is a water tank ball valve that controls the water in or out of a holding tank. Typically, buying a valve with approvals is more expensive than one without, so ensure you require one with approvals.

The 2-way function of a drinking water ball valve means it has two ports, an inlet and an outlet, and a ball with a bore in it. They are operated by a manual hand lever to turn the ball 90 degrees. Simply turn the handle perpendicular to the pipe to close it and parallel to the pipe to open it. 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 are known for 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 very less 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 compared to other types of housing material and provides 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.
