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:Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?
The C indicates that the material is carbon steel and does not indicate cast iron (generally omitted)
Q:Butterfly valve D71X-16 and D71X-16Q what is the difference?
Q should be made up of their own, generally 16, behind the body material, C carbon steel, P stainless steel, etc., have not seen Q, and 16, no symbol behind, representing the cast iron,
Q:What do D71, D371 and D341 represent in butterfly valves?
D71 is a handle to clip butterfly valveD371 is a turbine to clip butterfly valveD341 is a manually operated double flanged butterfly valve
Q:Gate valve, butterfly valve and so on can do the valve so that?
Yes, but the accuracy of the adjustment is not high. Just about. To adjust the flow, please use flow control valve.
Q:What does "D41X-16" mean?
There are many kinds of valves, so each valve has a specific model. Butterfly valve D41X-16 code D refers to the butterfly valve, 4 refers to the connection form is flange, 1 refers to the drive mode is manual, X is the valve sealing ring material is rubber, 16 refers to pressure, 16 kg. Valve model is composed of seven elements: valve type, connection form, drive mode, structure, sealing ring material, nominal pressure, material. You can ask me if you don't understand. Dual valve []
Q:How to calculate the size of the manual butterfly valve?
[1] type code, transmission mode, connection form, structure form, sealing surface material or lining material, nominal pressure, valve body material, this is the most basic arrangement way now D341X-16C. [2]: butterfly valve 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 air water, steam, and all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow. 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:What does "C" in D971F-16C DN450 RF mean for electric butterfly valves?
Valve carbon steel -16c body 316 stainless steel -16r
Q:How do the butterfly valves d341 and d343 differ in appearance?
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. According to type code, transmission mode, connection form, structure form, sealing surface material or lining material, nominal pressure, material of valve body, regulate butterfly valve type.
Q:Butterfly valve D71X-10 and butterfly D371X-10 what is the difference?
One more 3 in D71X-10 stands for adding a worm gear to the valve. What are the same, the difference is driven by the handle into the drive, gear drive, worm gear drive for large caliber butterfly valve a little less, because the valve torque is big, big, hard to handle and can rotate, and if the worm, you can turn a few laps handwheel. If there are other questions, we can continue to ask questions, the city butterfly valve manufacturers
Q:Butterfly valve model D373F-16C, ask God answers
D - butterfly valve, 3 - turbine rotation, 7- clamp type, 3- eccentric F - sealing surface for PTFE sealing, 16- bearing pressure 16KG, C - body material cast steel
