3. Feature:
This valve is mainly composed of body, butterfly plate, valve shaft, seat and transmission devices. Simple and compact structure, small portable, convenient for transport, install and dismantle. 90 degrees of opening and closing, switch quickly, operating is small, light energy; Sealing performance is good, service life is long, can achieve zero leakages. Flow curve tending to straight line, excellent regulation performance.
Electric actuators can be divided into basic, overall switch model, external regulation as a whole. Electric device can provide or customer designated brand.
4. Sealability:
The valve for rubber seal, closing butterfly plate and seat sealing performance is good, two-way sealed good performance and the torque is small. the friction is very small between butterfly plate and the seat seal. The valve shaft drive the butterfly plate, butterfly plate do 90 degrees rotation. Butterfly plate flexible for opening and closing, no card acerbity, beating phenomenon, small torque.
- 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:What's the use of fire butterfly valve?
- Fire butterfly valve is the abbreviation of fire signal butterfly valve, which belongs to a kind of fire valve.Fire valve is an important accessory on the industrial and building pipelines. The fire fighting valve is composed of three parts: valve body, headstock gear and valve cover. Among them, the fire signal butterfly valve has the advantages of simple structure, reliable sealing, light opening, long life, convenient maintenance and so on. It is widely used in water supply and drainage, building, fire fighting systems, all kinds of pipelines, especially in fire lines.
- Q:Butterfly valve common faults and treatment methods?
- Three, summary:Only familiar with every detail of circulating water pump outlet valve and butterfly valve equipment, timely and thorough maintenance and strict debugging, to ensure the safety and reliability of equipment operation, to ensure the healthy and orderly operation of equipment.
- Q:How to calculate the size of the manual butterfly valve?
- I don't know what size you mean, and what about DN in diameter, such as DN125, which means 125 cm in diameter
- Q:i have a slightly small mitral valve leak in my heart. my cardiologist say nothing to worry about, but i am not sure. can some one explain if it would eventually lead to some complications?
- Mitral valve prolapse is the most common cardiac problem and may affect five to twenty percent of the population. The condition is most common in women, although men are also affected. With MVP, symptoms do not begin before the early teenage years (approximately age 14 in girls and 15 in boys), but adults of any age may be affected. MVP tends to run in families, so those with blood relatives with MVP have a greater chance of also having the condition. If a person has mild MVP, he/she needs no restriction of exercise. But if the MVP is big, then it is a different thing. Because, though complications in this condition are very less, people who suffer from this condition have to take extreme care. In case of large MVP, you may have to cut down on your physical activity, have a surgery and may be put you on medications like beta blockers. If the valve is truly defective (not just 'prolapsed'), it is serious. Unfortunately, doctors have mistaken a 'differently shaped' mitral valve as a disease in itself. And this is where the non-disease comes in. In simple terms, a mitral valve that appears prolapsed is usually normal. It still is not clear to experts why some mitral valves appear prolapsed and allow some blood leakage backwards. I have an answer for that phenomenon, but the important point is that the disease is a non-disease.

- Q:The difference between vertical and horizontal butterfly valves in municipal water supply
- Vertical and horizontal only installation directions and installation methods are different. Functionally, there is no difference.The main difference between the two methods of installation is that:1. horizontal can effectively avoid the high temperature radiation above the pipe. The disadvantage is that it takes up a lot of space.The advantage of the 2. vertical is that the occupation space is smaller, and it is easy to install. If the pipeline is higher, it is not convenient for maintenance.
- Q:Does the pneumatic butterfly valve need electricity?
- Definitely need control, so be sure to have electricity. You can control the switch on and off. If necessary, this valve can contact me.
- Q:How does the pneumatic butterfly valve control the angle of opening?
- The angle of the rotating shaft is controlled so that the angle of the butterfly valve is controlled. You just have a good electrical locator
