Q: Ball valve specifications 1/2 inches corresponding to DN?: I know that. 1/2 stands for DN15. 3/4 stands for DN20. Ha ha, unfortunately no points

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: What is the difference between ball valve and butterfly valve?: The two kinds of valves can be distinguished from their names. Ball valve cut-off is a ball in the valve to achieve, the ball blocked the pipeline will not flow, move away on the circulation. The closing effect of the butterfly valve is two or one butterfly wing, just like butterfly wings, or, like a blade, the shop is expanded and sealed, and the pipe is out of circulation. Plainly, one is blocking with the ball, and the other is blocking with the blade.

Q: One stainless steel ball, two pieces, three pieces of difference, use: Structural features of two piece ball valve:1, opening and closing without friction. This function completely solve the traditional valve because of the friction between the sealing surface and affect the sealing problem.2, top structure. The valve installed on the pipeline can be directly checked and maintained, which can effectively reduce the device parking and reduce the cost.3, single seat design. The utility model eliminates the problem that the medium of the valve in the valve is influenced by the abnormal voltage increase.4 、 low torque design. Special structural design of the valve stem, with only a small hand, the valve can easily open and close.5 wedge sealing structure. Valve is provided by the mechanical force of the valve stem, the ball wedge to the seat and seal, so that the valve sealing is not affected by changes in pipe pressure, in a variety of conditions, sealing performance has a reliable guarantee.6. Self-cleaning structure of sealing surface. When the ball roll off the seat when the fluid in the pipeline along the sealing surface of the sphere into 360 degrees evenly through, not only eliminates the high speed fluid on the seat of local scour, also washed away the sediment on the sealing face, achieve the purpose of cleaning.

Q: Where to buy the ball valve?: Ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of media flow, it only need to rotate 90 degrees of operation and a small rotating torque can be closed tight. Ball valve is the most suitable switch, cut off the use.

Q: What's the difference between a copper ball valve and a stainless steel ball valve?: The difference between copper ball valve and stainless steel ball valve:1, they use the material is completely different, steel ball valve adopts copper, stainless steel ball valve is stainless steel.2, copper ball valve corrosion resistance is excellent, switch operation is smooth, labor-saving, durable without leakage. Stainless steel will not cause corrosion, pitting corrosion, corrosion or wear, and high temperature resistance. The average stainless steel is more expensive.3, according to the same pressure environment, the price is stainless steel cheaper, and copper ball valve medium temperature is much higher than the stainless steel ball valve, if the medium temperature is too high. Copper ball valve must be used! If the medium temperature is not more than 80 degrees. With stainless steel ball valve on it

Q: I design water meter transformation, 50WPD table, the original table before the installation of 50 anti-theft valve, table after the installation of 50 of the globe valve; master let me put anti-theft valve into anti-theft gate valve. Switch the stop valve to the gate valve. I'd like to ask what kind of valve is appropriate Why? And I checked from the Internet that the ball valve is generally used for small aperture, this aperture range is how much? Why?No copy paste, thank you......: First, the advantages and disadvantages of the ball valve1, advantages:Minimum flow resistance (actual 0);Because it is not stuck at work (without lubricant), it can be reliably applied to corrosive media and low boiling liquid;Complete sealing can be achieved in larger pressure and temperature range;It can realize quick opening and closing, and the opening and closing time of some structures is only 0.05~0.1s, so that it can be used in the automation system of the test stand. Quick opening and closing valve, operation without shock;The spherical closure can be automatically positioned at the boundary position;The working medium in the two-sided reliable seal;In the fully open and fully closed, the ball and seat sealing surface and the dielectric isolation, the high-speed media through the valve sealing surface will not cause erosion;It has the advantages of compact structure, light weight, it could be considered for most reasonable structure of the valve system of medium low temperature;To body symmetry, especially the welded body structure, can well withstand the stress from the pipe;The closure of parts can withstand the pressure differential.11;They all welded ball valve can be buried underground, so that the valve parts from erosion, the maximum life of up to 30 years, is the most ideal oil and natural gas pipeline valve.

Q: What does "41H" mean in the ball valve Q41H-16?: Q41H-16 in ball valve 41H stands forQ stands for ball valvesThe drive mode is manual (omitted)The 4 connection type is flange connectionThe 1 representative structure is the floating ball direct flow channelH: alloy steel sealing surfaceThank you, that's over.

Q: What's a twin hot melt ball valve?: Is a plastic ball valve, connecting France is hot melt.

Q: Ball valve, PTFE pad inappropriate choice, is not easy to bad ah?: 120 - 150. TemperatureChasing the answerYes, but not in a high temperature for a long time, like more than 180 degrees centigrade. Because the gasket can not be used after deformation, it will cause valve leakage.

Our company is specialized in the production of a series of products, such as knife style gate valves, various types of metal hard sealed ball valves, PTFE soft sealed ball valves, high temperature and pressure wrought steel ball valves, eccentric semi-spherical valves and three way valves (T-pattern, Y-pattern and L-pattern), which are designed and manufactured according to international standards, like GB, ANSI/API, JIS and DIN. The main body materials of valves are LCB and LF.
