2.Feature

1, the slip joint consists of ontology, the short tube, pressure and sealing ring, bolt and force of pressure.

2, general installation on the upstream side of the valve or other device. The slip joint for pipe flanges, upstream of downstream of valve. The slip joint force stud were deeper than the back of the companion flange, pipeline companion flange and valve through the nut, for the connection of tube and valve upstream and downstream equipment.

3, need to remove the valve, to force no lag bolt end flange pipe (side) of the nut loose behind the companion flange, then stretched to shorten the tube on the side of the nut to loosen the flange pipe direction. And then fixed through stud square head, rotate the nut on the reverse of the expansion pipe companion flange, make the move to the telescopic pipe flange pipe end. In the event of a reasonable interval can be removed after. Then unscrew all force stud on all nuts, make force bolt from one side to unload. Remove the valve.

Q: Where is the Shanghai valve? What brand is good?: To tell the truth, I think the Shanghai Yang Yi valve is good, in product quality, as well as product packaging are very good, especially after sale service, are free of charge

Q: Where is the valve used?: Water treatment, chemical, petroleum, biological pharmacy and so on are more used

Q: Look at the flow chart, some of the valves are marked with FV, and some are marked with XV. What does that mean?And what do you mean by the Cv value on the valve nameplate?I hope the heroes give a clear explanation ah, it is best to give an introduction of this knowledge of the web site oh.Thank again.: FV or LV on the flow chart, which represents the instrument bit number, FV is flow valve, and LV is level valve.The valve on the nameplate CV value, it is a measure of the size of the valve flow, it is the concept of 40 - 60 degrees Fahrenheit in the water, the pressure drop of 1 psi, in a valve opening per minute flow through the valve (U.S. gallons).

Q: What does "DN15" mean? What does "PN 16" mean?: Valve nominal diameter 15mm, valve nominal pressure 1.6MPa
