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: I just installed three anti-siphon valves(jar top,orbit) for a sprinkler system the main water line is 3/4 then goes into my manifold (pvc)3/4 schedule 40,usually when you turn on the water it comes to a stop where you re valves begin then you either open them manually or their set up through you re timer, the problem im having when i open the main water line the water goes straight through the valves without me even opening them my question is can it be to much pressure or what can the problem be? any info helps thank you: Orbit Anti Siphon Valve

Q: Where is the Canister vent shut valve located on a 2003 honda crv: 2003 Honda Civic P1457

Q: i have a puegeot 306 turbo diesel and apparently removing the EGR valve helps with engine noise and the smokeyness of the car. Is there any downside to removing it?: yep good gas milage

Q: I just dropped my 3rd valve slide from my trumpet on the ground. It fell with the curved end first. I can't see any dents and it doesn't look bent, but I oiled it and everything and it's really hard to move. Could it be bent? How can I fix it?: Be sure that it is aligned correctly when you place it back in the valve casing. When you are putting it back in, it has to turn until you hear a click, indicating that the valve guide has fallen in the right space. This aligns the valve with all the ports. (The valve guide is a small plastic piece located under the valve spring. This valve guide must snap into a little notch inside the casing. When it does, the valve will be perfectly aligned. You will know when the valve guide is in the right place because you will feel and hear a click and the valve will not rotate any longer.) After thorough cleaning, oiling, and correct valve placement, if you still notice it sticking, take it to a repair shop to have it chemically cleaned. They are typically very good and will ensure your trumpet is in proper playing condition.

Q: The hot water shutoff valve to the washing machine was dripping. I removed the packing nut and put in new packing over the weekend. Problem is that the packing nut seems to only go back on at an angle no matter what I do...it may have already been that way though. The valve isn't currently dripping, but I'm not liking the way the packing nut only goes on at an angle. Would it be crazy to keep the existing valve if I keep an eye on it and over time it doesn't drip, or is it too risky to keep this valve given that the packing nut is on at a funny angle? (Local plumbers here in Northern NJ all want around $350 if I were to replace both the hot and cold with a watts single handle valve.) Thanks, J.: It is your house if your uncomfortable with the packing nut being cross threaded then have it replaced otherwise if it isn't leaking just keep an eye on it. by chance do you turn your water valves on and off alot? because if you do you are causing the packing to deteriorate.

Q: I went to the cardiologist yesterday and I was diagnosed with leaky aortic valve. I really want to know more information on it, but i cant find anything. I have two questions:- is aortic valve leakage and aortic valve regurgitation the same thing?- can somebody give me some background information or some articles for me to read so i know how to keep it minor?also heres some family history:My Dad- Arrhythmia, Heart Murmurs, something with Coronary ArtaryMy Mom- Mitral ValveMy (twin) brother- Bicupsive Valve My sister - she has heart papitations, but we dont know what it isim 15 year old girl (if it helps)and right now its not too serious: I okorder

Q: Just wanted to know what the significance of the number of valves is?I know that theres valves for intake and exhaust if i'm correct.if there is four i'm guessing its 1 for air and 1 for fuel if its fuel injected. and 2 for exhaust?are there bikes with 3 valves or more than 4 valves and why?and a basic carburated 2 stroke just has an intake from the carb side and then an exhaust.please give me more info and let me know if i'm correct or not.: It's two intake valves and two exhaust valves. The intake valves both have the same fuel/air mix going through them. It just gives the engine a bigger port to send the mixture through. Thus sending more fuel/air mix into the engine for more power. It's easier to fit four smaller valves than it is to fit two big valves into the combustion chamber. And the two exhaust valves give a bigger port to get the burned gas out of the combustion chamber faster.

Q: instead of just buying a replacement, is there an easy way off the valve to check if it's still good?: dio, yes, if your sprinkler control valve is not opening a zone valve in the automatic mode, then manually turn the solenoid on the zone valve counterclockwise, it sprinklers come on , then you have confirmed a bad solenoid. these can be purchased seperately or another oprtion is a complete zone valve dio, well, if water is flowing thru then the solenoid is not sealing on the zone valve body itslef. unless there is debris between the solenoid washer and zone valve body, then sounds like a bad solenoid...

Q: 1991 Buick Spirit smokes early for five minutes in morning, from exhaust. Tried every carburator and gas cleanative fluid. Mechanic says Valve job'.: Probably just the valve stem seals need replacing. NOT a entire 'valve job'. The seals help scrape oil off of valve stem to lower the amount of oil weeping into cylinder when engine is running or turned off. As the rubber ages, it cracks and loses its elasticity and doesn't wipe the stem properly. This is a lot cheaper versus a full 3-angle valve job which requires removal of the heads.. Get a second opinion.
