6. Continuous quality improvement and new designs development.

7. Reasonable and stable price

8. Meets different countries standards, such as ANSI,DIN,BS etc.

 

The main  points

1.Recommend to use butt welding flange,Do not use flat welding flange because steel pipe can easily meetdics to affect opening and closing freely disc if steel pipe enter flat

welding flange;                                        

2.The inner diameter of flange can not be too small or too big and must confirm the dimension of flange sothat the disc can turn free;                                        

3.For advoding scalding the seat ,Do not weld flange after the butterfly valve was installed in pipe.

Q:Are fire fighting signal valves and signal butterfly valves the same thing?
The same nature: both can open and close, there is also information back fed.Signal valves are collectively referred to as signal butterfly valves.
Q:What does butterfly valve nps12cl150d373f4-150lb stand for?
NPS (Nominal, Pipe, Size) abbreviation. Refers to the connection (including flanged and welding end) of the nominal diameter, followed by a digital unit is American Standard inches, 12 inches.NPS12 labeling system.CL is the abbreviation for class, and LB150 means the pressure is 150 poundsD stands for butterfly valves3 is expressed in the form of a turbine drive7 means of connection: to clip3 means sealing: 3 eccentricF4: the sealing material is PTFE
Q:How to control the single acting pneumatic butterfly valve?
There are single acting pneumatic head, we must pay attention to often open or normally closed, we must pay attention to.
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:Butterfly valve model D344H and D343 difference
In fact, almost all refers to the sealed variable eccentric butterfly valve.1, D344H-10C DN4002, D343H-10C DN400Let's talk about the similarities between the 2 Butterfly models: D stands for butterfly valves, 3 represents turbine drivers, and the middle 4 represents flanged connections,10 represents the pressure of 10 kg, C represents the butterfly valve, the material is cast steel, and DN400 stands for the caliber of the valve;To say that where there are differences between the 2 models, there is a place where there are differences, second means 4 of the first models is the new type sealing valve structure is variable eccentric, second of the second models of the 3 represents the structure of the valve is three eccentric, and three eccentric seal variable eccentric type is in fact a meaning.Sealed three eccentric butterfly valve, sealed variable eccentric butterfly valve, corresponding to the central butterfly valve and sealed single eccentric butterfly valve.
Q:How can the flange butterfly valve be installed on the pipe?
Direction.Butterfly valve in theory can be installed in any direction, it is recommended that the horizontal installation of the valve shaft installation, so that both ends of the bearings will not be at the bottom (below), so as to avoid sediment in the media into the bearing.Inlet pipe configuration.There are water inlet side valve elbow, tee pipe fluid caused by bending and uneven distribution of the inflow valve, the drift will occur in the pipe, so it must be generated by the uniform drift disposed on both sides of the disc, so as to avoid uneven force on both sides of the disc, and may produce additional torque.
Q:How can I get the fire signal butterfly valve?
At the input end of the input module, some resistors or terminals are added to the product
Q:Especially butterfly valve
Butterfly valve "opening - flow" curve in the flow of 25%-75%, that section is basically linear. That is, the opening of 40%, that flow is about 40%Butterfly valve opening degree of 0.5, should be opened 50%, that is, opening to 45 degrees;
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
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.
