FAQ of Cast Steel Check Valve:
Q1:I can’t find the type of steel check valve which I need. what can I do?
The chart above only lists out some common composition of steel check valve parts.We may provide other different parts material composition according to the customer's request or the actual valve working condition.
Q2:Which certification do your products pass?

- Q: what is the difference between mitral valve prolapes and mitral regurgitation?
- Mitral valve prolapse refers to a condition in which the leaflets of the valve are large and floppy compared to the average. When the ventricle contracts, the valve closes and the flow causes a pop as the floppy leaflet fills with blood, much like the way the wind fills a sail. This extra pop can be heard with a stethoscope (like a click) but it can often be felt by the person affected which makes them more aware of their heartbeat than the rest of us. Mitral Valve regurgitation is a condition in which the mitral valve leaks after it is closed leading to a loss of efficiency of blood pumping and a drop in blood pressure. It is often a small leak and is of little consequence and is often associated with mitral valve prolapse. This leak can sometimes be heard with a stethoscope as a murmur under the left arm. The combination of both situations is known as Barlow's click-murmur syndrome. Old Doc
- Q: In my condo, I have what appears to be a water relief valve of some sort right after my water inlet pipe. It's after the water cutoff valve. It's not the water heater relief valve. It has a leak, not bad, just a drip right now. It looks like a half baseball sticking out of the main inlet pipe with a bolt in the center of it. I've tried to tighten it but that makes the leak worse. First, what is this. Second, Is there an obvious fix to this. Third, if I have to get it replaced, what model/manufacturer can I get so that this doesn't happen for a long while. My plumbing is short of fifteen years old.
- It sounds like a cold water relief valve, also known as a thermal expansion valve. It leaks when your city pressure exceeds 100psi (factory setting) or the set pressure. Code requires pressure to be below 80 psi. A Watts 530C will do the trick. It is adjustable. It will cost you about $30.00 - $40.00 + labor to remove old install new. If it is a pressure reducing valve, a new one will cost about $125.00. It lowers your pressure when it exceeds max allowable per the plumbing code, 80 psi here in Florida. I use the Watts 1 25AUB-Z3 Pressure Reducing Valve for these applications and set it at 60 psi.
- Q: i have a 1997 dodge avenger ES with a 2.5L v6. im wondering if my EGR Valve could be bad i get about 14mpg on gas. my car has a poor idle but will not stall idle gets kinda bad if the airconditing is on. I did a complete tune up and yes it was done right. and i changed my Idle air control valve. after i changed the valve i drove a few miles and i got a check engine light for insuffecient EGR flow but then it went away and never came back. I took the valve off and cleaned it with carb cleaner. im trying to find out why my ide is kinda poor and if the car sits a few days it takes a little longer to start.my motor has 142k miles but has been properly maintained.
- The EGR must be closed at idle and open as you cross quicker. If your EGR have been caught closed, it could don't have any final result on driveability. If your EGR is caught open, probabilities are it in most cases may not idle for lengthy earlier than dieing. I could blank the MAF sensor placed simply after the air filter out. Use BrakeClean spray. You did not say whatever approximately the gas injectors. I could placed an injector cleanser within the tank (it would possibly not support however its inexpensive than exchanging them). You would dispose of the spark plugs and notice if any seem discolored indicating a persistant pass over. This would point out the cylinder or cylinders with disorders similar to plugged injector, dangerous coil, something.
- Q: I have 3 such valves in the line and none seem to be able to move past 10/4 oclock position and water remains on. Is there a way to adjust valve? Seems there is slot for screwdriver in center of valve.
- Jeff B is right, the screw you see is for taking off the handle, nothing more. A quarter turn should do it. If it doesn't turn, lightly tap on it as you do.
- Q: I have a training I will be attending on Valve actuator and subsequently an exam. I need fundamental knowledge of ROV. What are the types of ROV. The Maintenance Of ROV ? and the different Type of ROV actuators

- Q: also are those air flow limiting valves safe for the air pump to reduce the flow of air, I have one because the air bubbles are just way too many without one and it scares the fish away
- a check valve is to prevent back siphoning of water into the pump if you have a power outage or unplug the pump by accident. I'd suggest checking it by blowing through it the wrong way; if air does pass through get a new check valve (check new ones to be sure they don't limit airflow too much, and that the close in the wrong direction, many are cheap crap and don't work the day you buy them, so check them before you leave the store with it...note: same with thermometers, compare them with each other so you don't get the one that's crap) what you want is a normal air valve, they come in various configurations, one or more valves so as to run multiple airstones and to balance the airflow to each stone or ornament. You should not however just use the valve to limit airflow, as this damages the pump eventually. You can just let one of two valves bleed off a little air; however make sure another check valve is in the line from the tank to the valves or else you risk water coming out of that valve if it's lower than the tank water level.....You may want a smaller air pump or an adjustable one instead.
- Q: I been playing the trombone for 6 years, do you think i could learn to play the baritone easily,which baritone is easier,3 valve or 4 valve.
- The forth valve on the baritone is the same as the trigger on a trombone - it lowers the pitch 2 1/2 tones to extend the range downward, to assist in improving intonation, and to solve so tricky fingering problems. You can learn baritone quite easy, if you relate what you know on the trombone to it. Here is a quick lesson on valve playing. Trombone position Baritone valves 1 Open 2 2 3 1 4 1 2 5 2 3 6 1 3 7 1, 2 3 Trigger 4 On high F#, you must play 2 3 On High G, you must play 1 2 Good Luck! It is a great and wonderful instrument to learn, and will help you trombone playing, too!
- Q: I've just been told that I need to replace the valve cover gasket on my 97 Volvo 850.....to the tune of $650.00 .....ouch.....is it that difficult to fix?......can you use the red gasket sealant? is there a difference between the head gasket and the valve cover gasket.......yeah I know there probably is.......but when I look on line all i can find is head gaskets......no valve cover gaskets........which scares me into thinking they are the same thing.....i'm hopeing i'm wrong......if its the valve cover gasket it looks like it would be right on top of the engine and fairly accessable.......or am I wrong......sure would like to save the $650 if it is something i can do myself!!!!
- Valve Cover Gasket is a tuff thing to fix alone. I would say, take it to the shop and pay the $650.00- look at it like this, at least you will have a garentee if anything goes wrong you take that bad boy back and have them hook it up the right way! Best of Luck!
- Q: ok...i want to find a valve that controls air pressure so i can let it out in 2 different ways for my pneumatic potato gunwhat websites or stores sell this (not home depot)
- You might have to register on the site to order online. It is free. You can call them and order the catalog. It is free also. Hope this helps Email me if you want me to look it up in my catalog. Don't break any windows. Wingman
- Q: I have a intake valve leakage in both my car and truck. If there some sort of quick fix i could use to stop the leakage for about 1 month.
- IF the valves are correctly adjusted, then the only solution is a valve job. Certain vehicle engines are more prone to burning valves than others.
