Q:Can the inlet and outlet of butterfly valve be reversed? Why? What will happen if the reverse gear is installed?

Are butterfly valves and check valves fitted together?Butterfly valve is nothing positive and negative ah!

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: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

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 does "10" in the butterfly valve "D71X-10" mean?

Represents the nominal pressure, refers to the 10MPa pressure butterfly valve, Zhengzhou butterfly valve factory specializing in the manufacture.

Q:Electric butterfly valve (not take the lead) what do you mean?

Electric butterfly valve, as its name implies, consists of an electric actuator and butterfly valve, and the customer does not take the lead, that is, without the electric actuator, only the butterfly valve can be provided.

Q:What is the effect of nylon coating on butterfly valve plate? Thank you

Mainly media will not be contaminated by rust on the body, you should say that the central soft sealing butterfly valve, the central valve is generally cast steel or cast iron material, so useNylon coatingLining up. There are soft seals, sealing performance is relatively high

Q:My quot;check engine soonquot; light came on yesterday and soon after that I took it to the nearest Midas to have the diagnostic test run on it - they stated I needed an ERG valve. I have no clue what it is and was told that it could run $160. - $300. for my 1900 Astro van. what is an ERG valve? I have noticed that my van has a low humming sound when I'm driving it.

An egr valve is an exhaust gas recirculation valve, basicly it allows for exhaust gas to be routed into incoming air-fuel mix- it causes reduced emissions. They r expensive, know however that often when a diagnostic is run and egr is the read out alot of times its an O2 sensor(oxgyen sensor), the egr and O2 sensors work together so its hard for a computer to idenitify the exact prob, u can take ur van 2 an exhaust shop and have them inspect it. Which i highly recomend, that way u know 4 sure what the prob is. Good luk hope i helped!!!
