Wafer Butterfly Valve

Q:What are the butterfly valves models?: Divided by work pressure:(1) vacuum butterfly valve. Working pressure is lower than the standard atmospheric pressure butterfly valve.(2) low pressure butterfly valve. Butterfly valve with nominal pressure PN<1.6MPa.(3) medium pressure butterfly valve. Butterfly valve with nominal pressure PN 2.5--6.4MPa.(4) high pressure butterfly valve. Nominal pressure PN is 10. 0--80.0MPa butterfly valve.(5) ultra high pressure butterfly valve. Butterfly valve with nominal pressure PN>100MPa.At work temperature:(1) high temperature. T>450 degrees C butterfly valve.(2) medium temperature butterfly valve. 120 C<t<450 DEG butterfly valve.(3) normal temperature butterfly valve. A 40C<t<120 degree C butterfly valve.(4) low temperature butterfly valve. One 100<t< one, 40 degrees C butterfly valve.(5) ultra low temperature butterfly valve. T< one 100 degrees C butterfly valve.

Q:Gate valve, butterfly valve and so on can do the valve so that?: Do a lot of use valve and butterfly valve, pneumatic / hydraulic, or electric device, automatic control valve, adjust its switch angle, so as to achieve the purpose of regulation. For example, in the factory, in order to ensure the top pressure, then the pressure regulating valve, the valve is automatically adjusted by a butterfly valve! And there is also pressure regulator, pressure regulator valve series is used independently. Of course the more, is mainly used to adjust the flow!

Q:What's the difference between a butterfly valve and an eccentric butterfly valve? What is the difference in field applications?: Avoid friction and wear on the sealing surface!And, at the time of closing, and opening the opposite, there is a better sealing effect! Now generally use eccentric butterfly valve as the main. That's all I know! If there is any mistake, please forgive me!

Q:What does the triplex of pneumatic butterfly valve mean?: Generally referred to as "triple parts" as if: filter pressure reducing valve, solenoid valve, with the valve position feedback switch..

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:Butterfly valve use: 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. Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear.

Q:Transformer butterfly valve and pressure relief valve difference: The butterfly valve is usually fitted with an oil immersed transformer between the tank and the radiator to control the flow of oil between the transformer tank and the heat sink. When large power transformers are delivered, the radiators are usually individually packed to reduce transport sizes. The butterfly valve is closed to prevent the outside air or water from entering the transformer tank. When the transformer is transported to the installation site, the radiator is installed on the butterfly valve one by one. When the radiator is installed, the butterfly valve can be opened so that the oil flow between the transformer, the oil tank and the radiator can be circulated, so as to play the role of heat dissipation.When the transformer is running, it is found that when the radiator has seepage, the butterfly valve can be closed to avoid further leakage of transformer oil, and a new radiator can be replaced.

Q:What is the electric butterfly valve? Please, great God!: ZSDF type fire signal butterfly valve uses: top of the ZSDF type fire signal butterfly valve with the valve opening and closing signal device, when the valve is closed by 25% (open degree 4/1), the signal device output signal was mistakenly closed to the fire control center.

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:Whenever sports cars are referred, people talk in terms of 'valves'. ex: v8, v12 etc. What does this all mean? Also they sometimes say that a v8 makes a great noise. why? How does the number of valves effects the performance? Many thanks.: the v is in reference to the motor its in a v formation v8 4 cyliders on each side v6 3 per side v12 6 pre side now the valves is how many are in each cylinder you usually have 3 or 4 valves per cylinder the more valves the more horsepower the more cylinders the bigger the engine
