- Q:How much pressure can the flange ball valve withstand?
- How many can, each kind of pressure specification has the different material quality, the thickness request, the ball valve can also use in the high pressure class.
- Q:The difference between ball valve Q341F and Q347F
- Ball valves Q341F and Q347F are straight through flow, worm drive, flange connection, soft sealing form. Different from Q341F, it is a floating ball structure, and Q347F is a fixed ball structure.Model meaning: Q34 worm gear flange ball valve, 1: floating ball valve;
- Q:What do you mean by 266 in the 266 brass ball valve?
- so as to produce self number manufacturers and buyers recognition. 266 should be a category of the Le ball valve,. We do hydraulic valve production and maintenance, this problem is not corresponding, I do not know such a reasonable answer?.
- Q:What is the service valve?
- I said that the pipeline on the pipeline pigging long-distance, pigging requires this launcher equipment, is the pigging ball into the barrel inside, and then through the process so that the pig into the pipeline, detection of pipeline cleaning or other purposes.
- Q:Which one is more durable?
- Where can I distinguish it from the handle?!!In simple terms, the heavy ones need to wear a little longer
- Q:Daily maintenance of ball valve
- The new parts need to be cleaned before assemblingThe assembly should have metal fragments, fiber, fat is not allowed (except the requirement to use) dust and other impurities, foreign matter contamination, adhesion or remain in part into the cavity on the surface or, if the packing is micro discharge, to lock the stem nut.Note: do not lock too tight, usually lock 1/4 circle to 1 laps, the leak will stop.(A) disassemblyMake the valve in a half open position, flush and remove dangerous substances that may exist inside and outside the valve body.Close the ball valve, remove the connecting bolts and nuts on both sides of the flange, and then remove the valve completely from the line.In order to remove the drive - actuator, a connecting bracket, lock washer, stem nut, butterfly spring, glam, wear plates, valve stem packing.Remove the body cap connecting bolts and nuts, separate the valve cover from the valve body and take off the valve cover washer.Make sure the ball is in the "off" position, which can be easily removed from the valve body and then removed from the valve seat.A hole in the body downward nudge stem until completely removed, and then remove the packing ring and the O.Caution: Please operate carefully to avoid galling, stem surfaces and body packing box seals.B) reassembleCleaning and inspection of the parts removed, it is strongly recommended to use spare parts package replacement valve seat and valve cover, gaskets and other seals.Assemble in reverse order of disassembly.Cross the locking flange bolts with the specified torque.Lock the stem nut with the specified torque.
- Q:What does "DN PN" mean? DN25 PN18 stands for what is the thickness? With the usual said 4 in charge of what's the relationship?
- *DN25 nominal diameter 25MM*PN18 nominal pressure 18 kg / cm2
- Q:What is the maximum temperature resistance of the 304 stainless steel ball valve?
- What seal do you have?.PTFE sealing maximum temperature: 120 degreesMetal seal maximum temperature: 325-400 degrees, look at the manufacturers.
- Q:Role of ball valve DN20-Q11F-16
- Q11F ball valve is to control the circulation and cut-off of the pipeline medium.
- Q:What is a high handle ball valve? What's the difference between it and ordinary ball valve?
- Long distance between the valve casing and valve ball valve operating handle, mainly used for pipeline insulation, thermal insulation when the body is exposed in the insulation material,
