Depending on the application, you should determine which pvc ball valve type is the right one for you. You should consider different specifications such as pressure, size, temperature, number of ports, body materials, end connectors, and configurations.

Full Port Ball Valve
Full port or full bore ball valve is more expensive than other types. The oversized ball in the full port ball valve lowers the friction loss because the hole in this ball valve is the same size as the pipeline. Though the valve is larger, the flow is unrestricted in full port ball valve size.

Full bore ball valves are usually used for throttling applications in various systems with high flow coefficients and low pressure drops.

Standard Port Ball Valve
Compared to the full port, the standard port ball valve has a smaller port and ball. It’s less expensive but comes with a slightly restricted flow due to the pipe size. Though they are cheaper, they have higher pressure drops compared to other ball valve types. Standard port valves are great for systems with high flow coefficient, just lie full port valves.

V-Port Ball Valve
The V in the v-port ball valve represents either the shape of the seat or the shape of the ball. V ball valve enables you to control the opening and the closing better. The flow characteristic in this type is close to linear. The high velocities of the fluids used with such ball valves forced the designers to come up with generally more robust construction for them since these types of fluids quickly damage a standard valve.

Multi-Port Ball Valve
Multi-port ball valves have three or four ways with an L to T shaped hole in the middle. T valves can connect any pair of ports and the L valve can connect the center port to side ports. Inlet in a multi-port ball valve is usually orthogonal to the plane of the outlets. 4-way ball valves have 2 L-shaped ports in their ball known as X port.

Reduced-Port Ball Valve
Also known as RB, reduced-port ball valves or reduced bore the flow area is smaller than the pipe and the flow through the valve is one pipe size smaller than the valve’s pipe size. This type of ball valve creates a pressure drop in the pipeline.
