Q: Remove the handle and lever the stem rotation with a wrench,: Monel alloy is mainly applied to the valve in the medium containing hydrofluoric acid.6, Hastelloy alloy is mainly used in the valve of strong corrosive medium such as dilute sulphuric acid7, titanium alloy is mainly applicable to all kinds of strong corrosive medium valveRecommendations for the GB standard of steel and ASME second A copies at American Standard. For American Standard steel can also see ASME B16.34

Q: What's the valve specification DN20?: You should be asking, how many inches?DN20 is 3/4

Q: A kitchen, 2 bathrooms, in addition to the toilet, toilet (only cold water), the rest need hot and cold water supply, and hot water by solar water heaters and gas water heater selection. The kitchen is mainly a sink, each toilet for toilet, shower, washbasin, separate cold water faucet. I don't know how many metal materials I'll use now Thank youThe waterways are all dark!: PP-R ball valve (cold hot water pipe valve): solar water heater 2, gas water heater 2, 2 hot water pipe switching with 1, indoor main water supply valve 1, 2 toilet water supply valve 1, total 8.Eight character valve (angle valve): kitchen, dishes, basins 2, toilet, toilet 2, wash basin 4, total 8.Other: shower water mixing valve 2, water washing machine 2, 2 washbasin faucet, basin faucet dish 1.The water supply of solar water heater and gas water heater is calculated according to the hard connection of PP-R pipe.

Q: Can the gas valves be switched off regularly?: No one at home, there are children, stove use time is relatively long, the gas hose has not changed for a long time, as far as possible off the stove front valve. Regular checks are necessary. For a long time, try the stove before the valve is intact, hose aging, safety first. Selection of large brands of stoves, quality guaranteed

Q: Is the heat jacketed valve fitted with flanged flanges?: Insulation valve is the standard valve, just in order to ensure the link bolt flange to super space, usually a large ball than normal level, such as the use of the path is DN80 flange, flange is DN100, so is the standard, but the size of flange connecting with other valves are not the same.

Q: The total valve of my natural gas was closed by the attitude I tried. Now I can't open it. I need to use gas. Who knows how to drive it? What skills do I have? I'm talking about the main valve.: General domestic weather is more ball valve, counterclockwise turn 90 degrees can.

Q: What valve does the high pressure by-pass valve DN254 * 800 belong to?: This is because the bypass valve is a special valve and other valve type theory.This is custom-made valves, generally no inventory, and may not have the material you need. So it needs to be customized.I remember the German HORA had the valve, but the price was sky high.

Q: What does the valve QF mean?: Valve type, one of the contents, Q refers to the ball valve, F refers to the F-4 seals.

Q: How do you understand the valve Z41X-16?: This is a standard set, the landlord himself to check the JB/T308 standard, Baidu library, some, and is free to download:JB/T 308-2004 valve type method of preparation clear EditionZ = gate valve4 = connection: flange1 = structural form: open rod single gateX = sealing surface material: Rubber16 = nominal pressure: 1.6MPa16 there is no letter behind it indicates that the body is made of cast iron

Q: The low pressure in our factory is below 1.6Mpa, medium pressure is 2.5-6.4MPa, high pressure is 10-80MPa.Where's qusetion:1.6-2.5Mpa??? Which section does it belong to?. I think many of them are defined on the Internet But I didn't say, where's 6.4-10Mpa?: No 1.6-2.5Mpa levels are included in the range of the mid pressure valve.
