Usage and Features:
The metal-to-metal butterfly valve realize veritable zero leakage bu installing and elastic seal ring of stainless steel on the body:
Adjustable seal, lifetime of 100,000 times without leakage
Special seal structure: Seal won't be deformed with the force, with no leakage under high temperature and cold condition
Three-eccentric structure, separated if open and sealed if closed
It solves the wearing problem of seal faces to avoid seay leakage by axial positioner, and the actuator can be installed at any direction
It is applicable to the cleaning pipelines of foodstuff, pharmacy, petrochemical industrial, Industrial Environment protection, Water Solution, high building and water treatment, supplying and drain pipelines as open/closed function or adjust the flow.

- 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: What do you mean by manual butterfly valve DN100 D341X-10?
- DN100 refers to the inside diameter of the butterfly valveD stands for butterfly valves3 represents the turbine drive4 represents the flange connectionThe 1 represents straight throughX is the representative of the Dengqen rubber seal10 represents the pressure of 1.0Mpa (10 kg)Manual butterfly valve, also known as turn over plate valve, is a simple structure of the control valve, but also can be used for low pressure pipe medium switch control. 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 working principle of the electric butterfly valve, and what's the difference between the butterfly valve and the butterfly valve?
- General large bore turbine.What is the difference between worm gear pair butterfly valve and center line worm gear butterfly valve?The structure is the same, but the model is different, the central line refers to the butterfly valve, an eccentric structure (371), the clip butterfly valve can do 371, you can do 373, etc.. In more detail, the clamp can be a midline type, 1 single eccentric, 2 double eccentric, 3 is 371372373 midline, then it can be flange connection, it can also be a pair of clamp connection
- 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.
- Q: That industry uses most of the butterfly valve, and only use the butterfly valve, a large number of use of butterfly valve, seek expert advice!
- See what kind of butterfly valve: 1., the use of all metal, mainly in the chemical industry.2. large diameter butterfly valve, mainly in low pressure water pipes and wind pipes3 environmental protection water treatment factory with more butterfly valve.
- Q: D what's the meaning of "one 71x one 1 butterfly"?
- According to the provisions of the JB/T 308-2004 valve type programming method:D== butterfly valve7== clip typeLinetype in 1==X== sealing surface material: Rubber-1== pressure rating: 1.0MPa
- Q: Hi guys, i asked a question before pertaining to the amount of cylinders and asking if it meant V4 or V6 or whatever.I actually meant to say VALVES, not cylinders. IS there a direct correlation between VALVES and Clyinders..Eg, My car, which is a 2001 Neon LE states right on the engine block quot;16 VALVEquot; in bright letters. I am sure this is a 4 cylinder engine. I haven't had a car that broadcasted the number of VALVES before. Another car I had broadcast that is was a 3.3 Liter V6 right on the engine.Is there a mathematical relationship between VALVES and cylinders, or would my car be braodcasting 16 VALVES, because a 4 cylinder doesn't typically HAVE 16 valves, or what is the story??Recently, I was looking at an altima, and it said 24 valves. Can you tell just by the number of valves if it is a 4 cylinder or 6 cylinder or whatever??Thanks.
- for every cylinder there is 4 valves..
- Q: When i waa replacing the valves in the las 4 valves , they dropped and i dont know how to make them go back up, and i dont want to take the engine out of the car, is there any tool to make the valve go back up or there is any way to do it?? People told me that i can crank it by and , but i dont know how to do it where do i have to do it, i need help please im begging for help!
- Engine dis-assembly is now required .
- Q: What type of butterfly valves do you have in DN125?
- 125D42X: manual double eccentric flange butterfly valve 125D3 (6, 9) 42X: worm (gas, electricity) double eccentric flange butterfly valve125D41X: manual single eccentric flange butterfly valve 125D3 (6, 9) 41X: worm (gas, electricity) moving single eccentric flange butterfly valve125D43H: manual three eccentric flange butterfly valve (hard seal)125D3 (6, 9) 43H: worm (gas, electricity) move three eccentric flange butterfly valve (hard seal)125D71X manual alignment type butterfly valve125D3 (6, 9) 71X worm (gas, electricity) midline type clip butterfly valve125D3 (6, 9) 73H, worm (gas, electricity) three eccentric pair clip butterfly valve (hard seal)125BD71 (F4) X corrosion resisting fluorine (wrapped) pair clip butterfly valve
- Q: Buried extension butterfly valve is buried or need to repair the valve well, can build the valve well, the extension rod butterfly valve installed in the valve well, the extension rod to avoid covers, the top of the valve well out, so that the hand wheel in the ground operation.Atlas S143 is less than the inner diameter of DN150 valve wells only 1200mm, DN200-DN250D diameter of only 1400mm, 700mm valve covers, valve rod and a handwheel to lengthen through the valve cover, valve wells is built to cover the embedded pipe or tube? Is there a standard atlas?
- It is better to set up the valve well for repairing the valve later;If it is extended to reveal the valve well, the waterproof of the well must also be considered. Otherwise, a rainy well will be full.
