Q: Ball valve specifications are represented by 2 FF,: FF refers to the form of connection between the valve and the pipe lineFF, or Flat Face, is a common form of flat flange connection

Q: Buy Ball Valves: Not let you buy the entire valve, you take this valve to the building materials market, see the valve handle can be sheathed in your valve stem, the valve handle is arranged to buy, your valve

Q: Gate valve, ball valve, the difference between the pressure regulating valve: The disadvantage is that the structure is complex and the height is large. The sealing surface is easy to wear. The sealing surface of the valve must be forced to close the valve to achieve sealing, in the same caliber, work pressure and the same drive device, the drive valve torque is 2.5~3.5 times the gate valve. This point should be noticed when adjusting the torque control mechanism of the electric valve. The sealing surface of the stop valve contacts each other only when the valve is completely closed, and the relative sliding amount between the valve core and the sealing surface is very small, so that the wear of the sealing cover is very small. The sealing surface of the valve cover, mostly due to the spool and sealing surface before the debris, or because of the closed state is not tight, causing the medium of high-speed erosion caused by. When the valve is installed, the medium can enter from the bottom of the valve core and enter the two way from the top. Medium from the spool into the advantages of the valve closed when the packing is not under pressure, can extend the service life of the packing, and can be pressure in front of the valve in the case of replacement of packing work. Medium from the spool into the bottom of the shortcomings of the valve driving torque is larger, about 1.05~1.08 times above the entrance, the stem by the axial force of large, easy to bend the stem.

Q: For the master enlighten Q47 ball seat spring hole number is determined by how: Force = spring stiffness (kg/mm) * compression volume (mm)Number of work cycles of spring stiffness = line diameter *1000/C 3 timesC= spring middle diameter / line diameterSpring diameter = spring outside diameter line diameter

Q: Can the check valve replace the ball valve?: Check valves are not a substitute for ball valves.Ball valve sealing is superior to all kinds of valves, ball valve according to the implementation of different control mechanisms, can achieve a variety of functions, throttling, regulating, temperature control, headstock, vacuum and so on. These are non-return valves that are not available.The main advantage of the check valve is that it can automatically prevent the backflow of medium and prevent back pressure, water hammer and other effects.

Q: Butterfly valve and ball how to distinguish from the appearance: See the ball valve and butterfly valve is round are generally seen in the way some can not see

Q: Is the water inlet valve good or the ball valve well?: Good with the gate valve, the ball valve requires more space than the gate valve.

Q: Why is there a water or oil in the new ball valve?: When the product goes out of the factory, we should do the closed water pressure test. There are two ways to check the spot and follow the pieces.

Q: Stainless steel ball valve, Q11F-10P, 16P, 11F, what does that mean?: Q11F-10P 16P is the meaning of stainless steel internal thread ball valve. One is 10 kilograms, one is 16 kilogramsQ valve Code: ball valveManual no code representation1 connection: internal thread1 structure form: floating through typeF sealing material: fluoroplastic10 valve pressure: 10 kg 1.0MPa 16=1.6mpaP body material: stainless steel
