FAQ

Three eccentric hard sealing butterfly valve, why not fit in the end of the pipe?

Three eccentric hard seal butterfly valve quality standards, up to zero leakage, but you mean the end of the direct discharge?If so, that's OK. First you have to calculate how much the pipe fluid pressure is.For example, the pipe fluid pressure is highest and the pressure is 1.6MPa (16 kg)Should choose three eccentric hard seal butterfly valve should be pressure 1.6MPa (16 kg)If you worry, optional 2.5MPa (25 kg) will not leak!Answer: three eccentric hard sealing butterfly valve can be installed at the end of the pipe

Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?

The C indicates that the material is carbon steel and does not indicate cast iron (generally omitted)

Butterfly valve D41W-1, 41, W, 1, respectively, what does that mean?

This butterfly valve in our factory called butterfly, 4 represents the connection of the flange connection flange is French, 41 in 1 on behalf of butterfly valve, W represents the body seal, is C that is actually the correct type of cast steel, should be D41W-1C. Suitable for ventilation, smoke, and these media.

Butterfly valve D71X-10 and butterfly D371X-10 what is the difference?

One more 3 in D71X-10 stands for adding a worm gear to the valve. What are the same, the difference is driven by the handle into the drive, gear drive, worm gear drive for large caliber butterfly valve a little less, because the valve torque is big, big, hard to handle and can rotate, and if the worm, you can turn a few laps handwheel. If there are other questions, we can continue to ask questions, the city butterfly valve manufacturers

What's the difference between electric butterfly valve and electric two way valve?

The electric two way valve is specially used for the fan coil of the central air conditioner. It is usually used in conjunction with the temperature controller. It can realize the automatic regulation of temperature. But the electric butterfly valve and the electric control valve belong to a kind of variety, and they are important execution units in the field of industrial automation control.

How can one - way sealed butterfly valves and two-way sealed butterfly valves be distinguished?

One way sealing butterfly valve is the front of the butterfly valve. When it closes, it must face the direction of the medium. The medium flows only in one direction, and the arrow on the valve body indicates the direction of the flow direction of the medium. Attention should be paid to the flow direction of the medium during installation. The two-way sealing butterfly valve is that the butterfly plate can face or back the direction of the medium, and the installation needs no attention to the direction of the flow of the medium, and the valve body also has no indication of the direction of the flow direction of the medium. Two way sealing butterfly valve stem force is greater than one-way butterfly valve stem. Design, the same diameter, pressure butterfly valve, two-way sealing butterfly valve stem diameter than one-way sealing butterfly valve stem diameter.

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.

The EGR valve is there to reduce nitrous oxide emissions and lower the temp of the combustion charge. This has the affect of reducing the octane requirement of the engine. This isn't a bad thing. When the valve hangs open, the thing will run bad at idle and could even die. The thing is, the valve could be perfectly fine and the sensor could be bad. Since some states won't give you a sticker if the light is on, you're probably stuck with replacement.

16 inches below the choice of electromagnetic valve can be the same, it turned out to be DN200 election 1/4, and now there are DN350 can also use this? With it, limiter, pressure relief valve, locator model will change?

DN200 pick 1/4DN350, DN400 corresponding solenoid valve, you can choose 3/8 hose 12mmOther accessories are related to valve path and pressure. If the same series, the valve has no change at all.
