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:
1、The 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:Ok i just be nt a valve on my 97 eclipse gst. I did a compression test and all my other cylinders were at 175psi which is good(thank god).My 3rd cylinder is only at 25psi.My mechanic will do the installation of the new valve but his friend has to do a valve job and re condition the whole head. Just because i guess your suppose to re condotion and clean the whiole head when this happens. What do u think a ball park estimate would be for this kind of work?I think he is going to replace all of the valves and seals y hes got the head off. The car has 100k on it and there is nothing else wrong with it. The guy i bought it from put a brand new bosch alternator and waterpump in and it also has a new timing belt so i dont have to worry about it skipping on me. WHAT DO YOU ALL THINK WHAT I SHOULD DO? HOW MUCH WILL IT BE? IS IT WORTH RECONDITIONING THE WHOLE HEAD? THX ALOT FOR YOUR INPUT.

- Q:The water shut off valve that is under my sink in the bathroom is leaking and I need to replace it. I am wondering if I need soder the new one or can I just put some thread tape around it.
- If it's a compression style valve, try tightening the nut some more to get it to stop leaking. If it's a screw-on, then yes, remove it and add more teflon tape-clockwise around the threads. If it's leaking around the stem, then all you might need to do it to tighten the packing nut a little-that's the nut directly behind the handle.
- 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:does that mean it doesnt work?, how can i tell if the egr valve works still?
- You didn't tell us year, make, model, and engine so we're shooting in the dark a bit. First off, EGR valves are NEVER on at idle. That would kill the engine. The vacuum only comes on when certain conditions are met. First, the engine has to be at full operating temp. Then, the throttle has to be open a certain amount. If you own a late model vehicle, many of them used duty cycle solenoids that literally pulse the length of time the vacuum solenoid allows vacuum to go to the EGR. That's how the computer regulates how far the valve opens. So, the only way to tell if yours is working without owning a scope is to use a hand vacuum pump and attach it to the vacuum port. Then apply vacuum and release it while watching the valve open and close. If you do this while the engine is running, the opening valve should make the engine run really rough, if not die completely. Next time please give us more make/model info
- Q:I have pressure steady at 13psi --- water temp is normal range but the external emergency run valve has been dripping since i turned the boiler on this year? Expansion take was empty, so I forced water through and then drained it and reopened the valve.....I am stuck and getting concerned. Anyone have a suggestion?Would really apprecite it?Additional info:Boiler is a Gas Powered unit by MASTER from the 80's.....
- Not sure what you mean by an emergency run valve. Are you talking about a relief valve? This will have a tag on it showing the relief pressure and has a lever to flip to check. Or is it an isolation valve that is leaking from the stem? If this is the case they usually have a packing nut that can be simply tightened to stop it from leaking.
- Q:i have a zone that - when turnd on by timer or manually only about 1 foot of spray comes out of sprinkler heads (used to wk fine). When i turn the ittle screw on top of valve (its about the size of a dime) water pressure comes up and wks fine - only water leaks at screw and when zone comes on next time NO pressure??? metal valves were just replaces about 1 yr ago.
- No. that's not gas tight and the plastic factors would possibly no longer delight in the petroleum ecosystem. you will choose a valve it is meant for propane. And the suitable valve would matter on the rigidity the place you meant to place in the valve interior the line. you will additionally would desire to layout the entire element very intently - no open touch relays - to steer away from a spark that would spark off errant propane.
- Q:I was diagnosed with Mitral Valve Prolapse. Does anyone else have this? Does this cause panic attacks? I have heard that. What other problems does it cause?
- My 8 yr. old son was thought to have this at birth, thankfully he out grew it It can cause your heart to beat rapidly, especially during physical activity. There are different types also, but mainly a valve in your heart is not formed correctly causing it not to seal witch creates the back flow of blood. Look up MVP on the web and you can find tons of info. on it! Also, make sure to have a sonogram and speak to a great cardiologist!
- Q:how hard is it to clean the egr valve on my 2002 Chevy Malibu? if you can give step by step or possibly a website/YouTube video link. thanks
- Cleaning it could make it worse then your experiencing now, but if you want to here's the steps. There are two bolts holding the EGR val;ve down. Remove them, and use a can of carb cleaner to clean the carbon out of the two ports that are in the valve. Reinstall with a new gasket and run the car. If the check engine light comes on replace it. I recently got a EGR valve (not recommended but they work) from a local wrecking yard for my folks '99 Venture 3.4 ltr motor, replaced the one on the van because it was throwing the EGR code and it worked fine. No more check engine light.
- Q:okay so i recently brought a trumpet and the valve keys were getting stuck. i used the valve oil and it worked. but then when i put the valve key back in and tried blowing through no sound came out. i think it's because i didnt put it back in right. now my question is how do i put it in right? i tried everything but it's still not making a sound. thanks,
- Unscrew the the valve cap on the appropriate under the button. attempt to softly pull the valve out. you may would desire to artwork it back and forth till it loosens up you may upload some oil around the the sting of the valve cylinder. as quickly as you have all 3 valves out sparkling each of the particles off of the valve, you ought to use an sos pad to get dissimilar the heaver stuff off. Wipe each factor off with slightly of lighter fluid and a sparkling rag. sparkling the valve bores including your snake. Stuff a rag down each hollow to get the stuff the snake loosened up. Reoil the valves and the cylinders and reassemble.
- Q:How do I adjust the valves on a 96 Blazer, 4.3 V6? When we tighten them to torque specs there is no compression, then when we loosen them and get compression, they loosen up to loose after its been running...any help!, THanks!
- There really is no setting for them, they are hydraulic lifters, tighten the lock nut down til zero lash, then tighten 3/4 turn more. if they are still noisy or loose they probably need to be replaced, if that is the case be sure to check and see if the cam needs to be replaced as well, chances are if the lifters need to be replaced so does the cam...you can run new lifters on an old cam...but Never run used lifters on a new cam. You can go to the Library and look this up in a chiltons or haines manual ... it will tell you the same thing.
