- 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: What is an electric two position butterfly valve?
- Electric double position butterfly valve belongs to a kind of electric valve and electric control valve. Double eccentric flanged butterfly valve, compact, the product can be used as pipe system shut-off valve, control valve and check valve. With manual control device, once the power failure occurs, you can temporarily manually operated, and will not affect the use. 90 degree rotary switch is easy, reliable and long service life. It is widely used in water supply, power plants, steel mills, paper making, chemical, catering and other systems for water supply, as a regulation and cut-off use.
- Q: Should I connect the butterfly valve before and after the pump? Or gate valve?
- This situation should use gate valveBecause it has the following advantages:1, the fluid resistance is small, the sealing surface by the erosion of small and medium Chong brush.2, opening and closing more effort.3, medium flow unrestricted, no disturb, do not reduce pressure.4. The shape is simple, the structure length is short, the manufacturing technology is good, and the scope of application is wide.Butterfly valve main deficiency is that it uses the pressure and temperature range is small.And poor sealing. Therefore, the gate valve should be preferred.Of course, there is also a multi-functional pump control valve is also very good, dedicated to the water supply system. Connection URL: (Reference), you can look at yourself, and I hope to help you.
- Q: Specifically an engine valve retainer.
- TRhe retainer and locks works together to hold valve to spring and keep valve from falling into the cylinder and spring from coming off the top. The locks are tappered, small end at bottom, big end at top. You compress the spring down, drop retainer over valve, put locks in groove of valve stem and pull up on the retainer to lock the retainer and locks in place, the relese the pressure off your spring compressor and the valve spring now holds pressure up on retainer which forces up on the big end of locks and holds everything together
- Q: What type of valve does the butterfly valve D343X DN300 represent?
- D butterfly valve, 3 worm gear, 4 flange type, 3 should be three eccentric X body, sealing surface for rubber, DN300 caliber 300MM
- Q: How do the butterfly valves d341 and d343 differ in appearance?
- Under normal circumstances, 41 is soft seal body, 43 is hard sealing valve body
- Q: The difference between the directly buried gate and the flange valve and butterfly valve
- The flange gate valve is stable and reliable when used in the pipeline, so the flange gate valve is used on the high pressure pipeline.Butterfly valve refers to the closure of parts (valve or butterfly plate) as 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. Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system, conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow.
- Q: What is the national standard for clip butterfly valves?
- GB/T 12238-2008 "flange and clip connection elastic seal butterfly valve"GB/T 26144-2010 flanged and clip on steel lined fluoroplastic butterfly valvesJB/T 8527-1997 "metal sealed butterfly valve"
- Q: e.g. a patient with a prosthetic aortic valve and a patient with a prosthetic mitral valve. Also, can you get stenosis of mechanical valves or just tissue grafts?Thanks!

- Q: What is the difference between wafer (flangeless) type and LUG type of butterfly valves?
- WAFER butterfly valve is the valve is divided into LUG (ears) with and without LUG, ordinary LUG without clip on 12 points in the direction of valve is generally two to four bolt holes was not, whereas the LUG of butterfly valve cross dispersed in a circle. Bolt hole. With LUG all bolted through the LUG, so that the butterfly valve and the clamp on the two flange connection is more solid, you check the valve picture, it is easy to understand
