What is the difference between a full port and a standard port plug valve?

Your industrial plug valves and their variations could get complex without the right guidance. These plug valves and their types are categorized according to port design, plug design, body design, and actuation type. 

Under the port design category fall the full port, standard, and the Venturi port plug valves. For this edition, you will get to know the full port and the standard plug valves. Below is the summary:

Full Port and Standard Port Industrial Plug Valves: The Similarities 

You wouldn’t appreciate their differences without knowing their similarities beforehand. These two valves both control flow using either a cylindrical or tapered plug. 

Also, both offer quick quarter-turn operations, and are reliable for shutoff industrial settings. Both are compact, strong, and suitable for handling a wide array of fluids in the most demanding environments.

The Differences: Full Port vs. Standard Port Industrial Plug Valves

Full port industrial plug valves and their standard counterparts are differed according to these points of comparison: flow path, pressure drop minimization capability, applications – such as for high-flow – and costs. Let’s tackle each.

Flow Paths

In valves, flow paths pertain to the routes or channels across which fluids travel the moment the valve is opened. The layout plays a crucial role on this.

Full port plug valves feature its internal diameter for the flow path the same size as pipe with which it is connected to, or perhaps even bigger. 

Meanwhile, standard port plug valves feature this bore that’s tinier than the pipe with which it’s connected to. 

Pressure Drop Minimization Capabilities

Since full port plug valves have a larger bore, this capability for them is better, allowing unrestricted flow of media, and minimizing pressure drop and turbulence. 

On the other hand, the smaller bore size of the standard version may result in flow restrictions, leading to higher pressure drops, compared to the former.

Applications and Uses

The former is ideal for industries that need to maintain high flow rates and where minimal pressure loss is critical. For instance, in oil and gas pipelines. Conversely, standard port plug valves are ideal for applications with more room for flow restrictions.

Costs

Which valve should you invest in? Well, full port plug valves are generally more expensive than the standard port plug valves.

What YOUFUMI Offers

YOUFUMI’s catalog of plug valves is of the lined type. However, our plug valves are made with large ports, featuring a cavity-free and dead zone-free design, which is responsible for preventing fluid media accumulation or contamination. You can rely on us with our large-scale manufacturing processes, employing standardization, universalization, and serialization principles along with advanced automated equipment. We are precise and we don’t compromise. Connect with us to find out more.
