Q: What does the "XV" valve mean?: XV if in front of the valve position, such as XV2211-011, then the XV indicates the switch valve, which is a representation of the Control Valve relative to the regulating valve.

Q: What does the "PN" mark on the valve mean?: The valve will usually be marked with "DN.PN." these two signs,DN refers to the valve path, and PN refers to the pressure levelFor example: DN25, PN16Refers to the valve diameter of 25mm valve, the pressure is 16 kg (1.6Mpa)

Q: and today the boss told me that I would like to do a valve of the commodity inspection information, and nothing else to me, which master taught meI am a professional intern, our company is doing the valve outlet, today my boss asked me to do a valve inspection data, what other data are not for me, which foreign trade master teach me ah, depressed ah ah ah???: National commodity inspection; stainless steel products; plastic tableware; domestic porcelain; toys; wooden products; furniture; bicycles; baby carriages; shoes; clothing; lamps and lanterns; plates; household appliances; bamboo / Wood / rattan / willow / grass / banana / vine furniture etc.

Q: G what's the meaning of the valve?: Valve with other function or with other special mechanism, fill in a Chinese language before the valve type code number

Q: What do you mean by "P54" in the valve z962y-p54 100V?: Applicable temperature 540 degrees centigrade；Applicable temperature 540 degrees centigrade

Q: How big valves are used in the DN90 pipeline?: If you use a 97 tube, the inner diameter of 89- phi 90., nominal pressure is low, then try to use DN80, DN80 valve diameter of 80, you can try butt welding

Q: The general signal valve installation, or other valve installation is not installed with the groove flange clamp hoop Yucca or direct way? What's the convenient way to install the following diagram? I don't understand. Neither groove, flange nor hoop.

Q: Why is the valve on the pipeline not the same size as the pipe, and how much of a crude pipe can be given? Thank youI'm sorry, I didn't make it clear that when doing pipe work in the factory, for example, 60 of the pipe, and in this pipeline to install the valve to choose DN50, and so on.: If the valve from the opening and closing role, then the valve bore should be the same diameter with the pipe, big waste, small, increase resistance.If the role of the valve is adjusted, and that caliber will be different from the pipe diameter, this is not to reduce the cost of the problem, is a result of calculation, and this calculation results with flow, pressure drop and valve resistance curve.For example, control valve, usually smaller than the pipe diameter, such as pressure reducing valve, will be smaller than the pipe diameter to two.
