Products Description of Swing Check Valve

Check valves are used in pipes under pressures between PN1.6~16.0MPa(Class150~2500Lb), working temperatures-196~600, They are used in industries include oil, chemistry, pharmaceutical, fertilizer, and power gene-ration to prevent the backward flux of the media.

The main structure features of Swing Check Valve:

1The products feature a reasonable structure, reliable seal, good performance and nice modeling.
2
Either soft or hard seal can be selected for the product upon different working conditions.The sealing face is built up with Co-based 
carbide alloy, leaving a better wearability, corrosion and scrap resistance and a longer duration.
3
Small opening pressure, the disc can be opened fully with a very small pressure differential.
4
Inside-set bolt-bearing structure reduces leakage and reliable use.
5
PN≥16.0Mpa (class1500), the middle cavity uses a self-tightening sealing structure to have the sealing performance reinforced along 
with the pressure rise so as to ensure the sealing performance.
6
Different parts materials and different sizes for flange, butt-welding are available for sensible combination according to different working facts and customers' requirements.

Q:why can't i just use solenoid valves hooked to a small bank of relays(using relay logic to control operation) connected to thermostats to control a multi zone boiler system? it would work, but can i do it, why must i use expensive zone valves?
Its just an educated guess but I would say it would cause system shock if a valve just snapped shut as against closing gently. Assuming the system was shutting down as a zone valve shuts the control switch opens and turns off the plant whilst the valve is still partly open. With a solenoid unless you fit a timer to pre shut off the plant then shut off the solenoid you would probably cause some plant damage. Also by the time you have wired all that lot up you may as well do the job with a zone valve.
Q:Im putting in a new EGR Valve for my 94' Mazda MX-3 V6 1.8L and i was wondering if anyone had a guide or some special tips on what or what not to do...Thanks.
Most of the time its not the EGR Valve, this something else. Do you no what code or codes were found ? I've seen the O-ring missing on the PVC valve alot and this trips a EGR code, Check the PVC Valve for the O-Rings or when the engines ruining open the oil cap and check to see if theres a large vacuum there. If so the O-ring is missing.
Q:Please suggest some design or sketch giving details of its operation. I need to operate valves on a natural gas pipeline with actuators to sense and operate the valve after recieving the signals from level switch in the system. Please help me understand the mechanism and operation philosophy.Please also suggest your email address as I may have to revert for subsequent questions on the same. Your addresses will be safe here and won't be passed on to any undesired sites. Be rest assured.

Q:I was wondering if anyone knew how important tire valve stem caps were in maintaining inflation pressure in auto tires? I noticed one of my tires losing air slowly (from 30 psi to 21 psi in about a week) and this tire (unlike the other three) also had a missing tire valve stem cap. I've just replaced it, and was wondering if a missing valve stem cap caused faster loss of tire pressure.
Tire valve caps are the final seal again potential failure in the valve of the valve stem. A good tire valve cap will come with high quality rubber seal that push against the circumferential 'ring' of the valve stem and thereby help to contain the air should the valve fail or not containing the air very well. You observation of your tire (the one with the missing cap) losing air confirms that this could be a possibility. Of course, the other possibility is that your tire is having a slow leak - go to any petrol station, and it could be rectified at a minimal cost. Note: Even if the valve is perfectly good, if the tire go over a bump or pot hole, it is still susceptible to lost of air due to the additional pressure asserted during the hit.
Q:I was told on Tuesday that i have mitral valve prolapse and that i inherited it and that i will be fine. Well i take toporol xl 50 mg because the mitral valve prolapse makes my heart beat fast. For the past week i have noticed that my chest/lungs get tight, kind of like i have congestion in my chest, it comes and goes and sometimes its really bad and sometimes i can tolerate it. Is this normal for someone with the mitral valve condition. My cardiologist didn't go into details about the symptoms and i'm wondering if i should go see another doctor. I do have a sniffly nose and was wondering if this could be symptoms of a cold or something else. Any one out their with my condition having the same problems??? If so what is it???
I have mitral valve prolapse and have lived with it for quite a while. I take no medications for it all. It's more common in females than males, and is usually not a cause of major concern. If your symptoms are worse than before you were diagnosed than you should consult your MD . Some people with mitral valve prolapse require surgery but that is rather uncommon. As with any heart issues there are degrees of involvement. Ask your MD to order an Echo-Cardiogram. It is a non-invasive test, painless and simple. That with whatever other test your MD may suggest should determine how bad the prolapse is. See a (Cardiologist ) is my recommendation. The symptoms that you are having are quite common with this condition, all except the sniffles.
Q:Exactly what is an EGR valve where is it located?
EGR is exhaust gas recirculation. Nothing more than to help out the environment. Simply puts exhaust gasses back through the motor to reduce (NOx). Since the exhaust gas is very stable (inert) it will not burn again, lowering combustion chamber temps when introduced. As mentioned it is a ufo looking piece, usually located in the engine bay where it can be seen.
Q:she 13 and shes always sleeping what is a leaky valve there not telling me enough for me to understand and im a nurse tech im scared for her
I'm okorder /
Q:1995 Firebird - with digital EGR valve, I think when the engine is at idle, it would be closed, I think.Anyway, this EGR valve has 3 holes that open up whenever.I noticed that the plastic housing on them is melting a little, which probably isn't anything.but I felt around it, and I feel a little air coming out, not from the gasket part, but maybe it has a leak in one of those solnoids somewhere.My cars been idling really ruff, do you think a leak in that would cause it to idle ruff?when I drive, it's fine, runs smooth, but stopping it idles ruff.I just bought that EGR valve 2 years ago, I don't know why it would melt.
Take the EGR valve off and see if it is internally caked with carbon. Also look at the ports it lines up to on the plenum and see if they are also clogged with carbon. If they are, remove the air intake tube from the throttle body and open the throttle plate. See if the intake plenum is also clogged with carbon. If so, and I think it is, you will need to get yourself a cumbustion chamber cleaning. Those 90s GM cars were bad for this. This will make it idle rough, and also lack as much power as it should have.
Q:I'm using a Yamaha double horn, and I reeeeeeealllyyyyy need to work on an audition for Monday. But my second valve is coming up slowly, which is a huge trouble 'cause all the pitches sound wrong!What do I do? I tried oiling the valve, that hasn't worked.
Try oiling the top and bottom bearing. One is located under the valve cap, at the top of that stem. You can see it turn when you move the valve. Put a few drops there and then move it. For the bottom bearing you need to turn the horn over and put some oil in the crack where the valve comes out of the valve case, under the string area. Again, oil it and let the oil get in while you move the valve.
Q:how do i adjust the valve lash my book sys to torque to 136 in lbs but my wrench is only in ft lbs
valve lash is a small gap between roker arm and valve bridge or valve top its main reson if any meatel heat then expend. it proper gap according to manual book intake valve gap less according to exhaust valve and fuel intake and exhaust out depend on valve gap you aslo called valve lash use for fuel setting.how time fuel in and how time exhaust out.
