Wafer Butterfly Valve

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?: DN200 pick 1/4DN350, DN400 corresponding solenoid valve, you can choose 3/8 hose 12mmOther accessories are related to valve path and pressure. If the same series, the valve has no change at all.

Q: I want to switch off the water in the bathroom only due to replacing sink taps, will water still come out of the pipe if i turn the stop valve: Assuming that the stop valves are good, turning them off will stop the flow of water to the sink taps. To test them, turn on the water faucet at the sink, then turn off both stop valves. The water should stop coming out of the faucet. If it continues to drip, the stop valves are defective and should be replaced when you do the job. If this is the case you'll have to shut off the main water valve or a valve upstream of the stops to replace them. Good Luck

Q: Are fire fighting signal valves and signal butterfly valves the same thing?: The same nature: both can open and close, there is also information back fed.Signal valves are collectively referred to as signal butterfly valves.

Q: The difference between the electric control valve and the electric butterfly valve, respectively, the application situation: Both are powered by electric butterfly valves.The control valve must have the ability to accept external signal control. At the same time, control signals and valves through the medium flow must ensure a certain relationship.Electric control valve belongs to electric butterfly valve; electric butterfly valve butterfly valve including but not exclusively butterfly valve.Electric butterfly valve is a kind of electric control valve.There are many types of valve body, usually through the single seat, straight through two seat, angle, diaphragm, small flow, three pass, eccentric rotation, butterfly, sleeve type, spherical and so on 10. In the selection of control valve valve prior to the media, process conditions and parameters to control the process of careful analysis, to collect sufficient data to understand the system requirements on the control valve, according to the data collected to determine the type of valve to be used.

Q: How warm is the PTFE butterfly valve?: Ordinary PTFE clip butterfly valve normal temperature tolerance of about 120 degrees, instantly to about 150 degrees

Q: Function of signal butterfly valve in fire sprinkler system: The signal butterfly valve is connected with the fire alarm system to monitor the switch status of the valve, thus effectively preventing misoperation

Q: What kinds of butterfly valves are available? What is the working principle of butterfly valves?: At work temperature:(1) high temperature. T>450 degrees C butterfly valve.(2) medium temperature butterfly valve. 120 C<t<450 DEG butterfly valve.(3) normal temperature butterfly valve. A 40C<t<120 degree C butterfly valve.(4) low temperature butterfly valve. One 100<t< one, 40 degrees C butterfly valve.(5) ultra low temperature butterfly valve. T< one 100 degrees C butterfly valve. Www bgfm /df/Divided by connection:1 pairs of clip butterfly valveThe butterfly plate of the clip butterfly valve is installed in the direction of the diameter of the pipe. The valve is fully open.The clip butterfly valve is simple in structure, small in size and light in weight. Butterfly valve has an elastic seal and metal seal two types of seals. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.2, flange butterfly valveThe flange butterfly valve is a vertical plate structure, and the stem is a sealing ring of an integral metal hard sealing valveFor flexible graphite plate and stainless steel plate composite structure, mounted on the valve body, butterfly plate sealing surface of stainless steel surfacing. The sealing ring of the soft sealing valve is made of nitrile rubber and is mounted on the butterfly plate.3, lug butterfly valve4 、 welded butterfly valveWelding type butterfly valve is a non sealed butterfly valve, widely used in medium temperature less than building materials, metallurgy and mining, electric power production process at 300 nominal pressure 0.1Mpa pipe, used to open and close connected, or adjust the medium quality.

Q: Do you use the straight stem butterfly valve in the fire fighting engineering?: Only the gate valve clearly rod and dark pole, butterfly valve classification is the clamp type and flange type, Zhengzhou butterfly valve factory, Mr. Zhao

Q: Butterfly valve in use when should pay attention to what problems?: In the process of using the butterfly valve, you should timely notice valve state, without excessive loosening, no abnormal leakage, or abnormal high temperature and so on, if there is abnormal, should immediately close the valve, to identify the reasons for the problem, treatment after use, it is also very important.

Q: Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?: D stands for butterfly valve. 71 represents the clamp type, X represents the sealing surface material, and 16 represents the valve to bear the pressure 1.6MPA, C position is the valve body material code, omitted to represent gray cast iron valve; C represents the valve body material is carbon steel.

Yue,located in Ducun Industrial Park, Linhu Town, Wuzhong District, Suzhou, mainly produces valves. Our company is equipped with one scale automatic static coating line, two assembly testing lines, many sets of semi-automatic assembly testing equipment as well as processing equipment such as 5m,3m and 2m vertical lathes, 4m and 2m milling machines and boring machines.
