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?
Our products are in accordance with ISO 9001、ISO 14001、API 6A、API 6D、TS CE、API607/6FA/BS6755.
- Q: I am trying to replace a leaky valve stem. And I didn't know how to get to the valve core and when I get there how do I change it? The charge is recovered. It is a 2000 Impala. Thanks in advance.Noah
- You say you want to change out the valve stem but can't find the valve core but the charge has been recovered. How did the charge get recovered without knowing where the valve core is. That's where the charge was recovered through. Also, if you have a leaking valve stem how did you still have a charge to recover, it would have leaked out through the leaking valve stem.
- Q: i have a 98 ford escort SE. oil spils out the dipstick. we think its the pressure release valve. sadly we dont know where that is. any imput would be great
- as they said, pcv valve. What you're describing is on a turbo- pressure exhaust valve.
- Q: What are better valve cover gaskets for a car? Cork kind? Or the rubber kind? Or either rubber/cork kind?
- For the inexperienced I would choose rubber it is harder to mess up by overtightening and if you clean the surface it will seal good
- Q: My electric water heater relief valve keeps opening 30 min after turning it on.I turned it down to 90F and 30 min later overflow again.when power is off no leak with the water on uld the valve be opening because of over heating?I know it does'nt leak with cold running through it.
- First you need to replace the relief valve. Once it opens, sediment sits in there and it will not shut off properly. If still happens after that, two things may be happening: either too much water pressure, or thermal expansion. -Check if your water main has pressure reducing valve, a check valve or a backflow preventer installed by the water meter, and make sure they're working properly. -If too much water pressure coming in to the house you need to install a pressure reducing valve in the water main, then you'll need a thermal expansion tank by the water heater. -If none of those item are installed by your water meter, most likely is only thermal expansion, and a thermal expansion tank will do the job.
- Q: Is this possible? The valve is way too big to fit the rim. Is there a special inner tube for this rim? Thanks in advance.
- Yeap, you need a tube with a Presta valve. Do not drill your Bontrager rims to te able to use your Schrader valve, you will ruin them. Also, the base of the valve will not fit the V of the Bontrager. The plastic cup can be discarded but you better keep it to help keep dirt out of the delicate threads and the seal. You can use the plastic cup also to make an adapter so you can use the Schader pump, just cut off the dome at the end of the cup and presto your Presta. Some people always use the cut-off cup to avoid bending and damaging the Presta valve, this is particularly recommended whem kids are going to use the pump. I have only broken a Presta valve myself but it does happen, sometimes they get decapitated. Now, you say that the inner tube is Specialized? You are not trying to put the valve through the hole with the cap on, are you? Just checking.
- Q: So i finaly got my check valve and my airstone. The airstone is actually a flat round airstone and is 5 inches in diameter to be in my 10gallon. Is it to big? though i have a tetra whisper air pump for 10-30g.And how do i place the check valve? Do i put it closer to the tank or closer to the pump? (just to make sure since i heard so many different ways people put it). Or does it even matter?And lastly, do i put the OUT side of the check valve facing towards the tank or the pump?Thanks! after this im ready to install it!
- Adequate the purpose you let a tank cycle in the first place is due to the fact of Bactria needs to grow that will maintain your water clear. As for overstocked. I consider your proper on the threshold of being over stocked. Just preserve the tank walking a lil longer and spot if it clears up. But when your 15 gallon tank has the filter from the ten gallon tank that could be why to you dont have sufficient water moving around to scrub it
- Q: sprinkler valve leaking
- Most valves are either 3/4 or 1 with female connections. Use the same size male adaptors with teflon tape wraped around the threads and screw it into the valves. Take a photo before you start to refer to when rewiring.
- Q: used in pipe line
- To allow adjustment for different pressures. The bellows extends under pressure. It works against the resistance of a spring to open the valve at the desired pressure.
- Q: Exactly what is an EGR valve where is it located?
- EGR valve is the Exhaust Gas Recycling valve. This is for when a motor is cold and needs extra fuel to keep running. Back in the days of chokes you would restrict the air going into the carburator to make the car run richer. With fuel injection cars more fuel is added to the engine to richen the mixture. This richer mixture causes the exhaust to have unburnt hydrocarbons, meaning not good for the environment. The EGR opens and allows some of the exhaust to be added back into the intake to be reburned. Once the engine warms up to operating tempurature the EGR closes. The EGR should be a UFO looking item about the diameter of a big coffee cup. Should be brownish metal, lightly rusted from the heat. A a steel pipe, around 1/2 to 1 inch in diameter, will run from the EGR to the exhaust at the back of the engine. Some EGR valves are on the front of the engine, some at the rear. Most frontwheel drive cars with will be right above the exhaust manifold on the front of the engine. Good luck and happy holidays
- Q: A friend of mine is having open-heart surgery next week to replace a heart valve. He needs to decide whether he wants a mechanical valve or a biological one. He is 28 years old. Which would you choose and why?
- Ask the surgeon which would be most appropriate in,If you trust your surgeon let him make the decision if you don't get a different surgeon.
