What is the main difference between a threaded globe valve and a socket globe valve?

The main difference between a threaded globe valve and a socket globe valve lies in the connection method and application scenario. ‌

Threaded globe valve

The stem thread of a threaded globe valve is located outside the shell and is not in direct contact with the working medium. Therefore, the stem thread is not corroded by the medium, is easy to lubricate, and is labor-saving to operate. This design makes the threaded globe valve suitable for occasions with a small nominal diameter and low medium operating temperature. ‌

Socket globe valve

The specific name of the socket globe valve may vary depending on the manufacturer or region, but it usually refers to a globe valve with a stem thread located inside the shell and in direct contact with the working medium. This design makes the stem thread susceptible to medium corrosion and cannot be lubricated. It is mostly used in occasions with a small nominal diameter and low medium operating temperature. ‌

Application scenarios and advantages and disadvantages ‌

Threaded globe valve‌: Because its stem thread is not corroded by the medium and is labor-saving to operate, it is suitable for occasions that require frequent operation or have high requirements for operating convenience. ‌

Socket globe valve‌: Due to its structural characteristics, it is suitable for occasions where the requirements for operating convenience are not high and the medium is highly corrosive. ‌ 

Through the above comparison, it can be seen that there are obvious differences in design, application scenarios, advantages and disadvantages between threaded globe valves and socket globe valves. The selection of suitable valves should be determined according to the specific use environment and needs.
