Description
Ball valve and brake valve belong to the same type of valves. The difference between them is that the closure member of ball valve is a sphere. The sphere has a hole (or port), and the flow will occur when the hole is in line with both ends of the valve. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. Ball valves can flexibly control the amount of flow and switch the flow direction. The sphere in valve is of floating type, therefore, under the function of pressure, it can generate a certain amount of displacement and press tightly on the sealing surface of exit end. In this way, this flanged floating ball valves can guarantee excellent sealing performance of exit end.
Application
Flanged floating ball valves are used for cutting off or connecting medium in pipe. They can be appropriate for various medium such as water, vapor, oil, liquefied gas, natural gas, coal gas, nitric acid, acetic acid, oxidant, carbamide, etc.
Features
1. Among all valves, flanged floating ball valves are the lowest in flowing resistance. When the ball valve opens, the sphere passageway, valve passageway and connecting pipe are in a same line, leading medium to flow through it without loss.
2. Flanged ball valves are easy to open and close, just needing to rotate 90°. Compared with other gate valves and globe valves of same specifications, ball valves are best suitable for pipe installation due to its small volume and light weight.
3. Flanged floating ball valves should be horizontally installed in pipe laying.
Advantages
1. Flanged ball valves are reliable in sealing. The materials of sealing adopt plastic, which is excellent in sealing and widely used in vacuum.
2. When the flanged floating ball valve is fully open or closed, the sealing surface of sphere and valve is isolated from medium. So it will not lead the corrosion of valve sealing.
3. This ball valve has wide applications. It can be used in drift diameters ranging from millimeters to several meters. It also can be used in high vacuum and high pressure conditions.
Attention
When choosing ball valves, sizes of drift diameter, scope of pressure, medium, product materials, and using temperature should be taken into consideration.
Operation
1. Before installing flanged floating ball valves, the medium in pipe should be cleaned.
2. When installing, some space should be left for handle to rotate.
3. To own longer operating life of flanged ball valves, customers should consider such factors as normal conditions, suitable temperature, reasonable corrosion degree, pressure ratio, etc.
Maintenance
1. Before putting flanged floating ball valves into use, pipe and valve flowing part should be cleaned to prevent from vestigital slag and other sundries.
2. Flanged ball valves adopt PTEE as its sealing materials. If the pipe and the ball valve should be cleaned, users should pay much attention to stay the sealing ring perfect when dismantling.
3. When cleaning flanged floating ball valve, the solvent should not generate chemical reaction with the parts needed to clean, and the solvent itself should have no corrosion.
4. Please make sure the vestigital dust, oil and other attachment are completely cleaned. If the water cannot achieve the clean standard, users can use ethyl alcohol to clean the special parts under the circumstances that there is no damage to valve and its components. The valve and components can only be assembled after volatilization of cleaner.
5. If flanged floating ball valve is stored in the open air for a long time, the valve body and components cannot use normally because of they may be corroded. Flanged ball valves should be stored to avoid rain, water and moisture.
6. If the valve is stored for 12 months or more, it should be tested before using to guarantee stable property.
Payment and Transportation
We accept the payment by T/T, D/P, D/A, L/C, etc. Our flanged floating ball valves can be transported by sea, railway, and airplane.
