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

Explore Tameson's wide range of manual 3-way PVC ball valves with ISO top from various global manufacturers. 3-way PVC ball valves with ISO top have a standardized mounting flange according to ISO 5211 to mount an electrical or pneumatic actuator. 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 of the drive shaft.

A 3-way 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 degrees or 180 degrees), 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 degrees 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.

PVC, a type of plastic, is lightweight, strong, and durable, giving it long service life. An electric PVC ball valve is often a cost-effective alternative to its metal housing (brass or stainless steel) counterpart as long as it is resistant to the media and the pressure/temperature range is suitable for PVC. A PVC ball valve with an actuator can be commonly seen in water management and irrigation applications. It is suitable for corrosive media like seawater, most acids and bases, salt solutions, and organic solvents. However, PVC should not be used for aromatic or chlorinated hydrocarbon media applications. The temperature range is from -15 to 60 degreeC (5 to 140 degreeF), and it has a lower pressure rating when compared to a brass or stainless steel housing.
