Q: Is the stainless steel ball valve forged steel ball? Which one is suitable for the gas pipeline? (FAQ: For example, the relationship between CF8M and F316.Natural gas pipelines look at bore, pressure, temperature, and composition.Clean natural gas with ordinary carbon steel ball valve on the line.Material basically A105N, LF2 based.As for pipes, I don't need to forge steel. My suggestion is that they should be made of forged steel.

Q: What's the diameter of the 4 point ball valve?: 4 points is 0.4 inches, 1 inches =25.4 mm.Then the 4 point ball valve diameter is 10.16mm.

Q: Gate valve, butterfly valve, ball valve advantages and disadvantages? What other commonly used valves?: Commonly used valves are: gate valve, globe valve, check valve, ball valve, butterfly valve, safety valve, regulating valve, plug valve and so onValve: valve is closed parts (RAM) vertical movement of the valve in the pipeline along the channel axis, used primarily as a medium cut that open and close use. In general, the valve can not be used as a regulation flow. The utility model can be applied to low temperature pressure, and can also be applied to high temperature and high pressure, and can be made according to different materials of the valve. But the valve is generally not used to transport mud and other media pipeline.Advantages: fluid resistance is small; the opening and closing torque needed by the smaller; can use the ring pipe flow to the two direction in the medium, that is to say the unrestricted flow of medium; the fully open, the sealing surface by the erosion of the working medium is smaller than the cut-off valve; the body has the advantages of simple structure, manufacturing good craft; the structure of relatively short length.Disadvantages: the size and height on the larger required installation space is larger; in the process of opening and closing, a relative friction sealing, friction is large, even scratch phenomenon caused by easily at high temperature; the valve has two sealing surface, to processing, polishing and maintenance of some increase the opening and closing time difficult.

Q: What does telescopic ball valve mean? What does it mean?: An expansion valve is mostly for repair or replacement of the water meter behind the expansion is the activity space, for example for water when the water meter is just let it back so easily won, for good and put it out to tighten the gentry good handle table.

Q: How much pressure DN65 ball valve?: DN65 represents the nominal diameter of the valve, which is known as "2 and a half inches" of the ball valve!How big is the pressure? The pressure is expressed in PN, and the pressure levels are divided into: PN0.6, PN1.0, PN1.6, PN2.0, PN2.5, etc.

Q: O ball as general regulation of opening extent: Hard seal can be adjusted, soft sealed, please be careful.The opening 0~90 curve is getting faster and faster

Q: For the master enlighten Q47 ball seat spring hole number is determined by how: Calculate each spring force, multiplied by the number. According to the manual valve design must be greater than the pressure, pressure ratio must be large than the material allowable pressure on the line. (emphasize that here because the production process of the spring, has value of many uncertain factors, so the actual production of the spring and you cannot calculate out the same, so please choose when to consider).

Q: Would you please tell me why the spring is placed in the valve seat? What's the function?: Valve seat on both sides should be added spring, the seal pushed to the valve core to seal up, so put the spring.

Q: DN20 pressure 6000PSI, one piece of thread on the threaded, full diameter ball valve body length and flow hole to how much?: Supplement: the above mentioned is just a pure design, such as the novice to do the design, checking and calculating of the general will, in fact in the reality of the design, the valve products have been very mature, as you say these are size, can refer to the same type with the specifications of the product parameters so, the more accurate calculation, experience is more important than calculation.

Q: PP-R double joint hot melt copper ball valve DN50 connection method how to connect?: There are two kinds of adjustable temperature control and fixed temperature control. The specifications are the same as those of the tube. It can be controlled by temperature control. It can be used in other material pipes. Such as: PE, PP and so on.
