Models and The Switch Direction of the Manual Ball Valve
What are the models of the manual ball valves?
In this article, Topper Valve will recommend the common models of manual ball valves.
The model of the manual screwed ball valve is Q11F-16.
The models of manual ball valves
The commonly used materials are stainless steel and brass.
The screwed ball valves are divided into one-piece ball valves, two-piece ball valves and three-piece ball valves.
The one-piece ball valve is composed of the ball, four-fluorine ring and lock nut. The ball diameter is slightly smaller than that inside the pipe. It is similar to the wide ball valve.
The two-piece ball valve is composed of two parts. The sealing effect is better than that of one-piece ball valves. The ball diameter is the same as the pipe diameter. It is easier to remove than a one-piece ball valve.
The three-piece ball valve is composed of three parts: the valve cover and the middle of the valve body. The three-piece ball valve is different from the two-piece ball valve and the one-piece ball valve. It is convenient for disassembly and maintenance.
How to distinguish one-piece ball valves, two-piece ball valves and three-piece ball valves?
The model of the manual flanged ball valve is Q41F-16.
The manual ball valve
Common materials are gray cast iron, cast steel, etc.
The flanged ball valve should be more extensive. It is more used in petroleum, chemical, water treatment and other fields.
The model of the manual welding ball valve is Q61F-25C.
The common material is cast steel. The welding ball valve can withstand greater pressure, and it has a fully welded structure. There will be no external leakage phenomenon. The main application areas are municipal construction, central heating, gas pipelines, etc.
The switch direction of the manual ball valve
In this article, we will also talk about the switch direction of the manual ball valve.
The switch direction of the manual ball valve
The switch of the manual ball valve is similar to that of the manual butterfly valve, which is operated by the handle or hand wheel to open and close the valve. The manual ball valve can be divided into screwed ball valves, flanged ball valves, and welding ball valves according to the connection form. These are several kinds of operations of the manual ball valve. The screwed ball valve is operated basically by the handle. There are two forms. They are handle operation and worm gear operation, which can be used for the flanged ball valve and the welding ball valve.
How to distinguish the switch direction of the manual ball valve? First of all, if the appearance of the ball valve is relatively new, there will be arrows and characters to show the direction of opening and closing on its handle or handwheel.
The manual ball valve
However, some friends will encounter such a situation like this. The ball valve has been installed on the pipeline for a very long time. The appearance is damaged more seriously. The logo or arrow on the handle or handwheel is blurred. It can not be identified. There is also a way to identify the switch direction of the manual ball valve. Turn the handle or handwheel counterclockwise, and the ball valve open. Turn the handle or hand wheel clockwise, and the ball valve close.
The switch direction of the manual ball valve
Finally, if the manual ball valve has been installed on the line, what if it is in the open or closed state? The handle ball valve can observe the direction of the handle. When the handle parallels the pipeline, the ball valve is open. If the handle is perpendicular to the pipe, the ball valve is closed.
This is our, Topper Valve for you to introduce the switch direction of the manual ball valve. If you want to know more about the knowledge of ball valves, please continue to focus on us.
