Analyze the advantages, disadvantages, and installation considerations of fluorine-lined stop valves

Thread Content

　　The advantages and disadvantages of fluorine-lined globe valves are quite evident, and many aspects need to be taken into consideration during their installation. Below, we will analyze the advantages and disadvantages of fluorine-lined globe valves as well as the matters related to their installation. Fluorinated-lined globe valves have the following advantages: 1. Small operating stroke and short opening/closing time. 2. It has a simple structure, making it convenient for manufacturing and maintenance. 3. It has good sealing performance, low friction between the sealing surfaces, and a long service life. The disadvantages of fluorinated-lined stop valves are as follows: 1. They are not suitable for media containing particles, with high viscosity, or prone to coking. 2. The fluid resistance is high, requiring significant force to open and close it. 3. The regulation performance is poor. Installation notes for fluorine-lined stop valves: 1. The handwheel, handle, and actuation mechanism must not be used for lifting purposes. 2. Globe valves operated by handwheels or handles can be installed at any position in the pipeline. 3. The flow direction of the medium should be consistent with the arrow indicated on the valve body. 　　The above are the advantages, disadvantages, and installation considerations of fluorine-lined globe valves.
