What advantage does the plug type disc globe valve have compared to the conventional disc type globe valve?

The plug type disc globe valve is designed with a unique geometry that enhances its ability to resist the cutting effects of dirt and scale present in fluids. This advantage arises from the way the valve's seal is constructed; it typically has a larger surface area and a more streamlined shape compared to conventional disc types. This design helps in minimizing wear and tear over time, making the valve more resilient when exposed to abrasive particles commonly found in liquid systems.

As a result of its robust construction, the plug type disc globe valve is often preferred in applications where the medium being handled might contain impurities that could damage the sealing surfaces of a standard disc valve. It maintains effective sealing performance even in less than ideal conditions, thus ensuring a longer service life and reducing the need for frequent maintenance or replacement. This characteristic is particularly important in plumbing and industrial applications, where reliability and durability are critical.
