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:Valve cover replacement?
if the gasket was replaced then there may be other problems. take it to a dealer or reputable mechanic.. what kind of oil do you use, have seen this problem with plugged oil return holes. builds up pressure in valve cover and pushes it out the gasket. penz and quaker are noted for this problem.
Q:Bent Valve!!!!!!!?
An okorder.com/
Q:I have 6 stations on my irrigation system, i can only find 2 valves outside.?
Yes, electric valves are set on the Mainline which is under pressure. Usually in a loop around the home with the valves set where the zone starts. Some are designed to have a short mainline with the valves set in a large box next to a vacuum breaker. All valves need wires that run from the clock. Sorbet can be found with a metal detector if you simply can't find them. You can also set them to go off manually time delayed a few minutes, enough to go listen to hear the valve opening.
Q:how to remove a stuck pcv valve?
the grommet is being replaced so do what you have to to get the valve out. id grab a hold with a pair of pliers and go that route.
Q:What is a foot and check valve what's the difference between the two?
A check valve is a mechanical device, a valve, that normally allows fluid or gas to flow through it in only one direction. A double check valve is often used as a backflow prevention device to keep potentially contaminated water from siphoning back into municipal water supply lines A foot valve is for use as inlet of suction pipe. A modified check valve that has a screen on the suction end to prevent debris from entering the pump or pipe. IIt protects against loss of prime, aids in priming the pump and protects the pump from large debris.
Q:What causes Emergency Valve on Boiler to Leak?
The TP valve will naturally wear out over time, if it has never popped open the washer inside of it has hardened, when you opened it it didn't seat properly when it closed back up, causing the drip. This is not an unusual or dangerous condition, the TP valve will usually wear out before the boiler does, it can be quickly and easily replaced. The valve will still function with a leak, but this reduces the efficiency of the boiler. DO NOT, under any conditions, DO NOT plug the leak by plugging the opening on the valve, this creates the potential for a very dangerous condition, let it drip until it can be replaced.
Q:why cant i get any valve gap om my 1600 beetle?
you MUST have the cylinder you are adjusting at TDC before adjusting the valves on that cylinder. take the dizzy cap off and rotate the engine clock-wise until the the rotor is pointing toward the #1 cylinder (the front at about 5 o'clock where the little notch in the case of the dizzy is) there is also a little V shaped notch in the crank pulley. this has to be aligned with the crack in the case at the top of the pulley. then take the valve cover off the right side of the motor and adjust the 2 valves toward the front of the engine (front is front of car) these are the intake and exhaust valves for the #1 cylinder. after you get them gaped to .006 snug the jam nut down. then rotate the crank EXACTLY 180 degrees counter-clockwise this will get you to TDC for #2. then adjust the back 2 valves on the right side of the motor (back is back of car) these are valves for #2 cylinder. then put the valve cover back on. rotate the engine another 180 degrees counter-clockwise, this will give you TDC for #3 which is the front left of the motor. adjust them and rotate the crank another and final 180 degrees counter-clockwise for #4 cylinder put the valve cover back on with new gaskets of course and you are done
Q:are the valves in my accord bent?
hey, the same thing happened to my car ok, you can fix it but it will take you a lot of time first, you will need to remove all the components such as alternator, exhaust headers , intake and head cover since you paid to get the belt put on, go ahead and mark it with a white out pen so you know where each tick mark goes and you dont have to pay again now you will need a deep 14 inch socket and a torque wrench ( can be borrowed from autozone ) now remove the 14 bolts carefully and lift the head straight up now that you have the head out, it is a good time to replace the head gasket as well take the head to a local machine shop and have it rectified now in a closed area remove the valves and valve covers and put in new ones then its just a matter of putting everything back together I wish I could help you cuz I know it sucks when this happens But go ahead and buy the Chilton book at your local Autozone and it has step by step instructions I took me about a week the first time I did this, and i was just a novice trying to avoid big charges :)
Q:Kitchen valve stem seems to be stripped?
Unfortunately most valves used today are made of plastic that only look like metal on the outside. Sounds to me like you and I live in the same house. I have to replace four different shut off valves because they are stripped. I am working on the kitchen one right now. Stripped Valve with no cold water and very little pressure in the other valve. If you ever have one replaced by a plumber, insist on all metal valves. I will physically inspect them from now on before they replace them. Once stripped nothing you can do but put a new one on.
Q:they say leaky valve now what ?
Leaky valve is generally refered to as back flow in mitral valve of the heart resulting into extreme debilitation and shortness of breath.Each heart beat sends blood leaking backwards through mitral valve making the heart work harder and harder to keep the blood circulating.No medication is available to treat or cure this condition.To correct the situation answer is either a mitral valve clip procedure or open heart surgery.
