Ball valve one-piece type and two-piece type which is better
Sep 18,2021 Posted by Bundor
Question: Hello, Bundor valve. Which one is better for one-piece ball valve or two-piece ball valve?
Answer: The one-piece ball valve is composed of a ball, a PTFE ring, and a lock nut. The diameter of the ball is slightly smaller than the diameter inside the pipe. The two-piece ball valve is composed of two parts, and the sealing effect is better than that of the one-piece ball valve. The diameter of the ball is the same as that of the pipe, and it is easier to disassemble than the one-piece ball valve.
The main difference between a one-piece ball valve and a two-piece ball valve is that the two-piece ball valve will have a better seal, and of course the price of the two-piece ball valve will be higher.
If you consider the cost of compression, choose a one-piece ball valve, if you want good quality, choose a two-piece ball valve.
The one-piece ball valve will be used for irrigation where the tightness requirements are not difficult, such as irrigation; while the two-piece ball valve is mostly used in power plants and large engineering projects.
There are several types of ball valves
The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. The ball valve is widely used in petroleum refining, long-distance pipeline, chemical industry, papermaking, pharmaceutical, water conservancy, electric power, municipal administration, steel and other industries. The types of ball valves used in different industries are different, so what are the types of ball valves? How many kinds of ball valves are there? In this article, BAND valve will take you to understand.
According to different classification methods, it can be divided into different types of ball valves.
According to the classification of functions, ball valves can be divided into bypass valves, air valves, pressure relief valves, and sewage valves;
Classification according to the driving mode: Ball valves can be divided into manual ball valves, pneumatic ball valves, electric ball valves, etc.;
According to the structural classification, ball valves can be divided into floating ball valves, fixed ball valves, orbital ball valves, V-shaped ball valves, and three-way ball valves;
According to the classification of valve body materials, ball valves can be divided into cast iron ball valves, cast steel ball valves, stainless steel ball valves, etc.;
According to the classification of connection methods, ball valves can be divided into flanged ball valves, threaded ball valves, welded ball valves, etc.;
First, I will introduce you so many ball valve classifications. Of course, there are far more types of ball valves. If you want to know the specific usage of various ball valves, you are welcome to inquire.
