Q: Butterfly valve use: Butterfly valve (English: butterfly valve) refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.

Q: When will Butterfly Valves be used?: 3, there are anti-corrosion requirements of the pipeline, such as sewage, chemicals, etc.;4 、 pipes that regulate flow control requirements, such as quantitative systems;5, there are open and close, fast opening and closing requirements of the protection of the pipeline system, rapid cutting......

Q: How does PLC control butterfly valves?: PLC control butterfly valve, usually control pneumatic butterfly valve or electric butterfly valve, see which way you control butterfly valve.PLC control pneumatic butterfly valve, that is, PLC program control, electric control, gas control, gas control butterfly valve;PLC control electric butterfly valve, that is, PLC program control electric, electric control butterfly valve.Ordinary switch butterfly valve is the program control on and off, to the 1 way valve open, to another 1 way valve off.

Q: For example, the arrow above is from left to right, and the direction of my current is from right to left. Is that ok? I have a diameter of 700 of the hard seal butterfly valve is so installed, but it will leak water, it will not leak, very serious: From the above example, it can be concluded that the arrow direction of the butterfly valve body refers to the direction of the pressure of the medium. Before the installation, the user must know the direction of the pressure of the valve after the valve is closed. The direction of the arrow of the free valve body is in accordance with the direction of the pressure of the medium, so that the correct use can be achieved, and the tightness of the valve body is kept in good condition.

Q: What is the butterfly valve: Conclusion: Although the double valve advanced technology, metrology, but must ensure stable and timely flow of materials, in order to achieve good results, so the combination of flotation system and dual use of butterfly valve can fundamentally solve the flow and measurement of powder, so as to rely on self weight principle of materials, so we plant layout the middle of a large number of mechanical equipment to save not only, more important to reduce the cost of investment and running.

Q: What's the difference between butterfly valves and check valves?: Butterfly valve is manual, only switch function.The check valve is an automatic valve, which prevents backflow of the pipe medium.

Q: can't locate freon intake valve for 03 jaguar an was wondering were it is located at: There is no Freon intake valve for an 03 Jaguar. Freon is R12 refrigerant and the vehicle uses an R134a refrigerant system. There is also no such thing as an intake valve on any vehicle refrigerant system. There is a high pressure port and a low pressure port. To answer your question: under the hood. Any other information would likely endanger your life, since this is obviously a DIY question and you lack the knowledge to safely recharge your vehicle's refrigerant system. R134a refrigerant, if inhaled, can kill you. Do not turn a DIY project into a DIE project. Leave the complicated stuff to the professionals.

Q: My quot;check engine soonquot; light came on yesterday and soon after that I took it to the nearest Midas to have the diagnostic test run on it - they stated I needed an ERG valve. I have no clue what it is and was told that it could run $160. - $300. for my 1900 Astro van. what is an ERG valve? I have noticed that my van has a low humming sound when I'm driving it.: Exhaust Gas Recirculation It redirects a portion of the exhaust gasses from the exhaust manifold back into the intake manifold so they can be re-burned. This is part of the emissions system that has been used since the early 70's.

Q: Which is better, the round two lobe butterfly valve?: Can be directly installed in the ventilation pipe, connected with the wind pipe, used to control the speed, adjust the indoor air, the double structure diagram can reduce the space length of the blade is unfolded, and also has the characteristics of small airflow resistance, convenient adjustment etc.
