The flexible butterfly valve is applicable to foodstuff, pharmacy, chemical industry, Prtroleum, electrical industry, textile, paper making, drain and air pipelines to control and stop the flow, with the function of compensating expansion and condensation inder the condition of temperature less than 80°C, nomral pressure less than 1.6MPa.
Main features:
Novel and resanalble design, unique structure, lightweight, convenient operation, quick open/close.
Flexible butterflyy valve is convenient to install, change and repair the valve, basides of adjusting and stop funtion and expansion and condensation funtion since temperature difference from compensation pipelines.
It is adjusttable and changeable for seal parts an reliable sealing function.

- Q:What's the difference between an electric two position control valve and an electric butterfly valve?
- With manual control device, once the power failure occurs, you can temporarily manually operated, and will not affect the use.The biggest difference is that the electric double bit butterfly valve can not fine adjustment; and the electric butterfly valve can play a regulating role.
- 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:How many kinds of butterfly valves are there?
- What's the score?There are central butterfly valve, double eccentric butterfly valve, three eccentric butterfly valveAnd according to the materialAnd according to the way of connection
- Q:The flow ratio of area and maximum flow area of the valve is? If it refers to the opening of the valve rotation angle? Butterfly linear closure refers to the butterfly valve at constant angular velocity close? When the change trend of flow is what? These valves problem bothering me for a long time,
- Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis rotation, so as to achieve the opening or closing or adjustment; actuators have electric or pneumatic, and so on, through the transmission device to drive the stem, valve plate rotation;
- Q:I have 1993 Seville 4.9. I got a new EGR valve but it didn't help. I tested it with vacuum pump, it won't hold pressure at all, same with old one. Is that new EGR valve bad or just different type of EGR that vacuum pump won't work? Thanks!
- The first source, pages 20-22, lists all 9 basic types of EGR valves. Not all the types are vacuum operated, but check out #5 and #6 - they behave very differently from each other without a real live exhaust system connected to them.
- Q:I have put a new pressure valve and replaced both thermostat
- If you have replaced the TP valve, more than likely there is a heating element shorted to the tank. This will cause continuous heating and high temp/high pressure...good luck.
- Q:Should I connect the butterfly valve before and after the pump? Or gate valve?
- Personally believe that import and export butterfly valve or gate valve can be, or other valves. One principle, easy installation and easy maintenance.As for how much pressure can be selected according to the size of the pump flange to set the general small caliber pump are 1 and 1.6 pressure general, unless you are a super high pressure multi-stage pump, generally 1 flanges fully meet the requirements of pump working pressure is generally not too high, living above the water temperature will not exceed 40 C, so you choose the space is still very large.
- Q:What are the advantages of butterfly valves?
- D. sediments are not readily accumulated;The E. is compact and has little installation
- Q:What does "D41X-16" mean?
- D butterfly valve, 41 flange connection, X rubber seal, 16 kg pressure
- Q:i just finished installing a sprinkler line for my lawn and i used anti siphon valves and 4quot; sprinkler heads. it says in the manual that it has to be at least 6quot; from the highest sprinkler. i think i made a mistake. i installed it 7quot; from the highest 'sprinkler line' . will i have a problem with that regarding the operation of the anti siphon valves and the sprinkler system itself?
- anti siphon valves are junk. just install regular valves and put in a backflow preventer on your mainline before all the valves, but right after the shut off vavles.
