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.
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.
Small opening pressure, the disc can be opened fully with a very small pressure differential.
Inside-set bolt-bearing structure reduces leakage and reliable use.
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.
Different parts materials and different sizes for flange, butt-welding are available for sensible combination according to different working facts and customers' requirements.

Q:Water shut off valve?
There is a cut off valve at the water meter.Before you get to deep in this,make sure the water is not running down the line from the tank it self.Dry the line coming out the tank with a paper towel just to make sure it is the valve leaking.Believe me,it can fool you.
Q:The pressure relief valve leaks on my electric water heater...?
First if you follow the correct procedure the pressure is no problem. 1 Kill the power or gas to the heater-very important for electirc elements will pop if not done before water is drained. 2 Hook up hose to drain on the bottom and open it up to flow water outside of home. 3.Open hot water valve on tub and sink to allow water to drain after you shut off the main water supply. 4.Shut off the main water supply and let tank drain for an hour. 5. Use a pipe wrench to remove old pressure relief valve. 6 Pipe dope new pressure relief valve and install. 7Open main water vlve and close and remove water hose on drain. 8Let water flow out of tub and sink for 5 minutes after air has bled out. 9Turn system back on and be sure check for leaks.
Q:exhaust valves material & dimensinons?
Most valves are made of forged steel. The dimensions depend on what car. You can get a factory manual for any car. Call a motor shop to order them. Don't try to make them yourself.
Q:Do blow-off valves cause problems in Audi tts?
Blow off valves are nice, but they aren't terribly good for your car. The main problem is that when the turbo isn't running, that open valve will suck unfiltered air into the engine and can seriously damage it. Blow offs are also pretty inefficient as you lose a good portion of the air in your turbo system. The best thing you can do is just get a good Forge diverter valve. Well made, looks nice, and will add a pretty decent amount of performance.
Q:Tough question about valves?
The flow coefficient is a measurement usually given for a valve fully open, identified in the specs as the Cv. It basically tells you how much flow you'll get through the valve for a given pressure differential across it, or conversely how much your pressure will drop if you force a certain volume through it. Some valve types are effectively orifices (gate valves) or short lengths of pipe (non-full-port ball valves), others like solenoid types have more complicated internal paths the reduce flow because of the fluid having to change directions in addition to squeezing through orifices.
Q:Whats wrong with my trumpets third valve slide!?
instead of the standard cheapo trumpet grease, try a more generic brass instrument oil. also make sure you aren't tightening the valve screw cap too tightly. it's not a good idea just keep tapping it. also, unwanted moisture can create a seal that will sometimes inhibit the valve from popping back up. get it dried out as much as you can. also, don't use too much of anything - the oil, the grease, etc - excess will keep it from popping out too.
Q:pressure release valve?
as they said, pcv valve. What you're describing is on a turbo- pressure exhaust valve.
Q:Is a EGR valve needed on a Pontiac Bonneville 3.8 liter?
If you live in a County that requires emission tests, most likely your car will not pass the inspection. I would have it change it is good for the environment as well as making your car more efficient.
Q:Plumbing question - Fill Valve?
The okorder.com. Type in toilet fill valve in the search box and click on SEARCH. You will see a list of How-To videos that will help you with this project.
Q:97 Escort. Trying to prevent the dreaded valve dropping. If I maintain the engine colder could the valve hold?
Those old escorts ran forever. I don't fully understand your question. Are you having any problems with the engine now? If the engine is running like it always has, I think you are worrying about a stray comment from a mechanic. If one of the valves seats moves out of position, you will know. The engine will start making ticking sounds and you may lose power. If none of that is happening, you are worried about nothing. If you are having some of those issues, then take the car to a competent mechanic have the problem diagnosed and get the head rebuilt. It's not that expensive on that engine. Then you will have new valves, new seats, new guides and a very clean head.
