Collection:3-Way Brass Ball Valves (ISO-Top)

Explore Tameson's wide range of 3-way brass ball valves with ISO top from various global manufacturers. A 3-way brass ball valve has three ports. They are available in two design types: L-port and T-port. This refers to the bore design in the ball, which is the media flow path. With a 3-way ball valve T-port or L-port, it is possible to mix, distribute, or divert the media flow. A 3-way T-port valve can be used for mixing media from two inlets into a single outlet or for distributing one inlet to two outlets. By changing the position of the handle (90 degree or 180 degree), you can change the circuit function. The 3-way L-port ball valve is designed for flow direction control. The L-port valve has a 90 degree bore inside of the ball, hence the name L-port. An example of an application is to have two inputs from separate tanks and one output, and you want to only use one of the inputs but always the one output. L-port ball valves can have 90 degree or 180 degree handles. Ones with a 180 degree turn allow you to disconnect both inputs from the output, allowing for no flow. Therefore, it is important to know your bore design to ensure your desired media flow, as the ports can be in different positions. The pressure inlet for 3-way ball valves is typically on the center borehole to avoid leakage unless defined otherwise in the product specifications. The selection of brass ball valves includes ISO-top valves with a mounting flange in accordance with ISO 5211. Due to this standardization, different brands/types of actuators can be used to drive the valve. There are various flange sizes in the ISO 5211 standard, such as F03, F04, and F05. Ensure that the actuator uses the same flange size and diameter as the drive shaft.

Brass is an alloy of copper and zinc and has great mechanical properties. Brass ball valves are known for their durability and no leakage over their lifespan, even if they have not been used for a long period of time. These ball valves can be used with drinking water, gas, mineral oils, compressed air, and many other non-aggressive media. However, they are not suitable for use with salt water or distilled water due to the risk of dezincification. Dezincification reduces the mechanical strength of the 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 as compared to other types of housing material and provides reliable sealing even in case of dirty media. Brass ball valves can withstand high pressure, high temperature, and high flow rates. Manual 3-way brass valves 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 a wide range of residential and industrial applications like controlling domestic hot and cold water systems, steam applications, irrigation systems, natural gas systems, marine industries, fire protection applications, and chemical industries.
