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:I have a 79 ford F-150 and i was wondering where the pcv valve was my truck will start but it wont idle until its reached normal operating temp i was told that it might be my pcv valve is that correct or what else could it be. thanks
You have a classic symptom of a bad EGR valve. The EGR valve lets exhaust gas bleed back into the intake manifold. I'm not sure exactly where it's at on your model truck, but there not hard to find. They usually have a vacuum diaphragm on the top. An actual Ford shop manual should have detailed instructions on how to troubleshoot.
Q:When looking at the head on my chevy 350 how do I determine which is the intake valve and which is the exhaust valve?
the intake valve is usually bigger and on the left. the exhaust valve is usually smaller and on the right. at least it is true in small engines (lawnmowers).
Q:Hi My sons car has alloy wheels, and metal valve stems, there is a tiny leak between the valve stam and the alloy on one wheel, we are struggling to get anyone to repair at a reasonable cost. Would tyre weld make a permanent repair?. Some tyre specialists won't touch the wheel, one other wants to drill out the stem put in another, which sounds a bit drastic. Any other ideas?, is it feasible to get the metal valve stem replaced by a rubber version?. Apparently the metal ones get curbed and then start to leak.
The leak is caused by corrosion of the alloy wheel in the hole that the metal valve stem goes through. You might try to let the air out and loosen the nut on the valve stem and spray penetrating oil on the o-ring which is on the base of the valve stem and is what holds the air in. Turn the stem back and forth a bit to mave the corrosion and then respray the o-ring. Tighten the stem nut, inflate the tire to 35 lbs. and spray a bit of soapy water on the stem to check for leaks. If it still leaks you will need to remove the tire and valve stem,clean the hole and surrounding area inside the rim and clean the valve stem and replace the o-ring. If the valve stem is a pressure sensor type for the tire air pressure monitoring system you may need to reprogram it. Only use plastic caps on the valve stem. Metal ones corrode on the stem and wreck them and never come off.
Q:So my engine was back firing and me and my dad adjusted all my valves both sides. Runs better, But it still back fires. What could be the problem? Its a Chevy 350 with a brand new mild cam. 600cc carburetor. And new shorty exhaust headers. However I don't have exhaust pipes on my headers just yet because I gotta get pipes to mesh properly with my exhaust. Could it be air coming back up from the pipes causing it to back fire a bit? Like I said we just adjusted all the valves.
Remove and look at the spark plugs. They should be TAN color. IF WHITE then you are running too lean or one of the vacuum hoses is sucking air because it is hard and cracked on the end. These are rubber hoses, so no cracks. If vacuum hoses are good then richen up the mixture for the engine. You will lose the backfiring. I am assuming that the distributor is set right so that the timing marks happen at the right place on the front pulley, of course.
Q:What are the function of reed valves on a motorcycle?
They allow a fuel/air mixture to enter the area under the piston in a two stroke engine on the compression stroke, as it is a one way valve when the piston is coming back down the gases are forced up through the tranfer ports into the combustion chamber.
Q:I have presta valves on my mountain bike now and only Presta valves can fit through the hole in the rim where the valve goes. If i want to start using Shrader valve tubes, because they are way more common and i can get them at Walmart, is it ok if i bore out the hole in my rim in order to get the Shrader valve to fit
Your tube probably has a Schrader valve, like a automobile tire. You can get these in the auto department of most stores and of course at auto parts stores. You might pickup a little dirt. Look at the valve to see if it's dirty. If so, press the center of the valve with a small object (small screwdriver maybe). This will blast the dirt out with air from the tube. Of course, you will then need to pump up the tire a little. If the valve gets dirty and you simply pump air in when the tire is soft or flat, you may force dirt into the valve which could cause the valve to leak. Schrader valves are replaceable. You can get these (and the tool to remove them) at an auto parts store.
Q:Which is worse ? And what causes it? I was told I had mitro valve prolapse but I m symptoms had worsen and so I saw a cardiologist again today and they said I have mitro valve regeritation.
MItral vale prolapse is the problem that is causing the regurgitation. Regurgitation is backward flow of blood. Prolapse is a situation where an anatomical part has slipped out of its normal position. When a heart valve is prolapsed it doesn't close completely, and blood leaks backwards when the heart beats.
Q:When i disconnected my Diverter Valve and made it non-recirculating i drove down the street and my engine cut out on me. it will go a few feet and after the excess pressure is released (PSHH) the car cuts out. i reconnected the valve tubing making it rec-circulating and it works fine. im baffled i know VW is supposed to run a DV but last night i saw a stock VW GOLF running blow off and he was stock. any ideas? it is an after market DV made by forge.
Yea... The 1.8T is made so you have to recirc your dv. You can run a BLOW OFF valve off of your throttle hose, but thats a lot of redirecting and work for some silly extra noise. Chip that Passat to get some more turbyturbo noise. Y was there a stock golf with a dv? I'm confused...
Q:ive had my yz250f for more than a year and i havent had the valves adjusted......it still starts up in under 5 kicks and rides great.......are there any signs that indicate you need your valves adjusted besides not being able to start it?
Yz250f Valve Adjustment
Q:any flash files explaining valve operation maintenance will be very much helpful
