Q: 16 inches below the choice of electromagnetic valve can be the same, it turned out to be DN200 election 1/4, and now there are DN350 can also use this? With it, limiter, pressure relief valve, locator model will change?: This is our company's products in Pucheng clean energy Co., Ltd. successful use case, if you need case details, you can give me a QQ number, I sent you. In addition, I suggest you add a pneumatic control valve, so that the safest, no map, I can give you. Saved is to look at the project site, if the north, the electromagnetic valve is recommended to use the 1/2 aperture, and a gas control valve or 1/4, it can guarantee the opening speed of the valve, special attention is on the use of the electromagnetic valve chain, this is very important, I will be the general experience specific issues to deal with specific, can not copy blindly, in most cases, this is no problem. And 1/4 also to see traffic, is also 1/4 solenoid valves, flow valve with big caliber is not the same, is not the same, the 1/4 path from the 2mm-12mm range, the CV value is small, about 0.1, with a large amount of 1.2, has big gap, valve opening time is also a great gap, to distinguish between the.

Q: Transformer butterfly valve and pressure relief valve difference: I don't know. Let's have a Baidu! Baidu is powerful.

Q: How do you draw the butterfly valve in the engineering drawing?: There is one of the most stupid way: find a picture of the butterfly valve, insert into the CAD, and then follow the trace, and there is a lot of CAD on the network of butterfly valve, yourself down..

Q: 1st where is my zone valve? I have an old Burnham gas baseboard heater2nd What do I do?My last resort is calling a proffesional.: You may have only one circulate pump on the boiler. If you want to check the zone valve there is a small handle on the valve you can lift up and this will open the valve manually. It will be found on the (usually) green valve on the return end of the copper pipe. It should have a red and white wire attached. If this is opened manually and you get heat you can replace the top half of the valve by twisting it off and exchanging it with a new one. I think they are around $35.00 bucks or so at Home depot. You can keep it open without and fear. This means you will only have a one zone boiler and all baseboard s will get heat instaed of being zoned

Q: Can the inlet and outlet of butterfly valve be reversed? Why? What will happen if the reverse gear is installed?: Hard seal butterfly valve in any case, the reverse loading will cause tight seal.

Q: What kinds of butterfly valves are available? What is the working principle of butterfly valves?: According to the form of sealing:(1) forced sealing butterfly valve.1) elastic sealing butterfly valve. The pressure of the valve seat, seat, or plate is produced when the seal is closed by the pressure from the valve.2) additional torque seal butterfly valve. The seal is produced by a torque that is applied to the valve shaft.(2) pressure sealed butterfly valve. The pressure is greater than the pressure on the seat or plate.(3) automatic sealing butterfly valve. The pressure of the seal is automatically generated by the pressure of the medium.Divided by work pressure:(1) vacuum butterfly valve. Working pressure is lower than the standard atmospheric pressure butterfly valve.(2) low pressure butterfly valve. Butterfly valve with nominal pressure PN<1.6MPa.(3) medium pressure butterfly valve. Butterfly valve with nominal pressure PN 2.5--6.4MPa.(4) high pressure butterfly valve. Nominal pressure PN is 10. 0--80.0MPa butterfly valve.(5) ultra high pressure butterfly valve. Butterfly valve with nominal pressure PN>100MPa.

Q: How does the pneumatic butterfly valve control the angle of opening?: The angle of the rotating shaft is controlled so that the angle of the butterfly valve is controlled. You just have a good electrical locator

Q: What does the butterfly valve model d344h, d345h, d346h, d347h mean?: According to the international standard of the letters and numbers apart to explain D344H D is a unit of butterfly valve, two unit 3 is driving mode: turbine, three unit 4 connection: flange connection, four unit 4 Structure: seal type linkage, five unit H sealing material: Cr13 stainless steelD345H compare yourself to the above. Unit 5 four is a sealed, single eccentric structureD346H four unit 6 is an unsealed center vertical plateD347H four unit 7 is unsealed double eccentricIn general, there is only one difference between them: the structural form is different!

Q: Who can give me a download UG butterfly valve, needle valve, diaphragm valve standard model address, Japanese standard, American Standard.: Support many 3D CAD format, such as the commonly used UG, Pro/E, SolidWorks......As for the butterfly you said, don't post the link up, the standard JIS, American Standard ANSI, German standard DIN are.You use Baidu Search "LinkAble PARTcommunity", after the open registration, CAD format, such as UG, ASAHI and then to find the manufacturer home page, which is the valve, you said the Japanese standard, German standard, American Standard valve basically all.
