The main structure of 815 & 830 series butterfly valve follows wafer amd flanged three-eccentric structure, but 815 & 830L series butterfly valve consist of body round with lugs and the desgin of single flange with bolting holes. 815 & 830 series buttferfly valve is widely applicable to petroleum, chemical industry, environmental protection water treatment, high building, water supplying and drain pipelines, and so on.
For the three-eccentric stucture, reliable sealing ability, it assure not to contact the seat when the disc is in open position and eliminate uneven load of the seats, extend the usage lifetime, and also assure the reliable sealing ability with high temperature resistant, friction resistant, corrosion resistant, etc.

- Q:How do you draw the butterfly valve in the engineering drawing?
- Butterfly valve there are many kinds of painting, according to the design institute out of the icon, below we together to understand the icon, which has the butterfly drawing.
- Q:What's the difference between D71X-16 and D71H-16 butterfly valves?
- Model D71X model means this, D represents butterfly valve, 7 represents butterfly connection form for clip type connection, 1 represents straight through, and 16 represents pressure 16 kg pressure.X stands for sealing and soft sealing, and the sealing surface is usually nbr.H stands for metal hard sealing, usually 2Cr13 surfacing.D71X-16 butterfly valve featuresIts main features are:1 、 the design is novel, reasonable, unique structure, light weight, fast opening and closing.2 、 small operating torque, easy operation, labor-saving and smart.3. It can be installed and maintained conveniently in any position.4, seals can be replaced, sealing performance is reliable, to achieve two-way sealing, zero leakage.5, sealing materials aging resistance, corrosion resistance, long service life and so on.
- Q:Do you use the straight stem butterfly valve in the fire fighting engineering?
- Bar valve bar, did not hear the bar with butterfly valve, ah, there are pairs of folder and hand wheel type bar
- 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
- The direction of the arrow on the valve body refers to the direction of the medium.Also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid. On the pipeline, mainly from cutting and throttling. 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:The flow ratio of area and maximum flow area of the valve is? If it refers to the opening of the valve rotation angle? Butterfly linear closure refers to the butterfly valve at constant angular velocity close? When the change trend of flow is what? These valves problem bothering me for a long time,
- Butterfly valve is fully open to fully closed is usually less than 90 degrees, the opening refers to the butterfly plate rotation angle;Linear closing should be the locator is linear, if the potentiometer is 0-10 euro, corresponding to 0-90 degrees, 500 Europe, opening 45 degrees;
- Q:Why use special flanges for butterfly valves?
- Mainly for clip type butterfly valve sealing ring on the valve body than the ordinary flange chip small diameter. Therefore, the ordinary flange can not guarantee the effective sealing effect. Therefore, you must use a dedicated butterfly flange sheet
- Q:What's the meaning of butterfly valve d371po?
- According to the provisions of the JB/T 308-2004 valve type programming method:D== butterfly valve3== transmission: worm gear7== connection mode: clip type1== structure: midlinePo== sealing surface material: lining PoPo== propylene oxide (PO)
- Q:What is the meaning of American Standard butterfly valve B series
- American Standard flange connection is divided into A, B series. A series for normal flanges, B series for compact flanges. 24 "to no AB series, flange standards for B16.5, 24" above B16.47.
- Q:When will Butterfly Valves be used?
- Butterfly valve is the most common and most widely used in the field of the valve, cases of sewage treatment, water supply, iron and steel, building construction and heating fields needs a lot of valves, especially with the hard seal butterfly valve butterfly valve position and a lot of popularity, the field is used more widely.
- Q:What are the advantages of butterfly valves?
- B. is cheap, especially when the caliber is big;C. the resistance loss is small and the fluid decreases through pressure;
