Q: Is the valve clockwise?: Tap water valve is generally divided into two kinds, one is ball valve, and the other is gate valve. The ball valve wrench is vertical when the water pipe is closed, is a twist or reverse, 90 degrees wrench and water pipe is open when the direction; valve handwheel clockwise turn off, anti clockwise turn is open. Valve in the application should not be twisted too tight, so as to avoid the thread buckle, spool off. Ball valve applications save effort and durability.

Q: How about the valve?: The British Hudson Valve Co. Ltd. (HUDDERSFIELD VALVES LIMITED), founded in 1964, its predecessor for the British metal parts company (ART METAL FABRICATION LTD AMF, referred to as LTD), located in the world famous one of the UK's Huddersfield valve production center (HUDDERSFIELD), the main production of various kinds of valve, valve cage valve and other valve manufacturers supporting. .

Q: What valve is the DN 25?: This is only the aperture of the valve. It does not represent the form of the valve.

Q: What does the 4 point valve mean?: That is not clear, American Standard or GB, or what other

Q: What are the other valves used for the control of dual-use items?: That is to say, your valve needs to be used as dual-use items and technology import and export licenses. Shanghai import and export can find me. We have electronic keys for dual-use items

Q: Valve pressure grade division: Valves are classified by pressure:Vacuum valve - valve with operating pressure below standard atmospheric pressure.Low pressure valve - nominal pressure PN is less than 1.6MPa valve.Medium pressure valve - nominal pressure PN 2.5~6.4MPa valve.High pressure valve - nominal pressure PN10.0~80.0MPa valve.Ultra high pressure valve - nominal pressure PN greater than 100MPa valve.

Q: How does the valve open?: This is a three pass, not a valve. It doesn't open often or often closes and there is no opening or closing. Can change the same caliber of the valve, you can use the handle switch.

Q: Tell me the exact address, or the phone number in the market. Where is the industrial zone (the valve) in Hefei? Please help, thank you: Hardware city inside, on the opposite side of the East Second Ring Guoqiang steel market

Q: What's the difference between a valve and a valve?: The valve does not have an Ethernet platform, and the "one" valve does not contain any other fittings.

Q: How can the material be checked by valve approach? What experiments do you need?: Under normal circumstances, in the selection of the valve has been considered the main components of the valve material, the use of the valve to determine (for example, media, temperature, pressure, etc.), the valve can not change the material used. For higher or special purpose valves, in addition to the normal valve strength, sealing test, the main material must be used for the inspection and confirmation. The chemical composition and mechanical properties of the valve body, valve cover, sealing surface, valve stem, packing and sealing parts shall be examined. Samples can be taken in bulk or tested with test sticks attached to the product.
