- Q:What are the advantages of butterfly valves?
- Butterfly valve, also known as shutter valve, its advantages are:A. has a large circulation capacity and is about 1.2 times the same size as two seat valves;
- Q:Butterfly valve switch direction respectively?
- First, if the butterfly valve has been installed on the pipe, you can first see the mark on the handwheel. Second, there is a switch indicator on the general worm gear.
- Q:Butterfly valve D71X-16 and D71X-16Q what is the difference?
- The two difference is that the body of the material is not the same, 16 behind with no sign, expressed as a default, is carbon steel (usually C), if you need to specify material, just behind with symbols, such as Q nodular cast iron, stainless steel P.
- Q:Butterfly valve model D344H and D343 difference
- [1] D344H-10C DN400, D343H-10C DN400, to talk about the 2 types of butterfly valves in common: D on behalf of 3 Representatives is butterfly valve, turbine driven, 4 representative is in the middle of flange, representing 10 kg pressure, C is the representative of the valve material is cast steel, DN400 represents the valve diameter; say that there the difference of 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 type variable eccentric in fact, is 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:What does "D341X-16Q" mean?What do D341-16Q letters and numbers mean for butterfly valves?
- D - valve type code: Butterfly valve;3 - valve drive mode code: worm gear;4 - valve connection form code: flange;1 - valve structure type code: vertical plate type;X - seat sealing surface or lining material code: rubber;16 - nominal pressure value: PN1.6MPa;Q - body material code: QT400 - 15.
- Q:In the pipeline attached building Atlas 05S502, in the middle of a water meter and check valve, the two sides are divided into two butterfly valve, want to ask why to arrange this way, what is the role of the two butterfly valve?
- Check the water gauge and check valve on both sides to facilitate the maintenance and replacement of water meter and check valve.
- Q:Butterfly valve is the control valve?
- The flow characteristics of butterfly valves can be approximately equal percentage characteristics, with the positioner can do adjust, is mainly used in large caliber, straight stroke control valve more than 200 volume weight will be great, it suggests using the butterfly valve.
- Q:What do you mean, handle, butterfly valve, hard back and soft back?
- The butterfly valve of the handle butterfly valve is installed in the direction of the diameter of the pipe. In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is between 0 degrees -90 degrees, when rotates to 90 degrees, the valve is fully open. This valve is mounted horizontally.Butterfly valve has an elastic seal and metal seal two types of seals. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.The hard back is the metal seal, and the soft back is the elastic seal.
- 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:Fire, the signal butterfly valve flange connection or welding?
- Grooved flange joint, welded flange connection! Wire bonding. Wire to flange connection! In addition, you can choose the groove type signal butterfly valve!
