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 have a curtis toledo compressor at my house. While moving it a helper dropped it on its side into the tank and broke off these 2 valves off the very top of the compressor. They had a copper line that ran off both of them and went over to the auto on/off switch, I'm guessing that's what it is. Where can I buy these or at least what are they called?
- The valves are probably one way check valves and the line is called the discharge line. The valves could also be un-loader valves that release the head pressure when the compressor shuts off. For parts just google your compressor brand and model for parts dealers.
- Q:What is the purpose of the LNG Vs Propane Valve that has to be installed on Gas Stoves/Ovens before use ? How can I set it myself for Propane ? What negligible effects would I experience if I hook a stove up to Propane while the valve is set-up for LNG ?Thank You !
- the reason for the difference in orifice size is pressure, not btu! propane is highly pressurized and uses a smaller jet. they use the same burners, so change the jets,, it is usually easy unless you have one of those that require a special tool,,
- Q:I have a 97 Neon. The Canister Purge Valve circuit gives a code 31 stating that it has a problem. I've replaced the valve, which didn't make the code go away. I removed the battery for a few hours, and the code went away. I drove for about 2 weeks and the code came back on. If it's not the valve, where do I look next?
- Could you describe this canister purge valve? Not sure what you are talking about here. Is it part of the emissions, part of the radiator, or what. I am just guessing it's part of the emissions. In which case, I need to know if it has a smog pump. Could be the pump, could be a clogged up cat, could be a bad EGR valve. Need some more info to help beyond this point. Good luck.
- Q:Our reactor is cooled by a cooling water system. The line pressure is around 4 bars and the pipe size is 42. How to select a good valve for that service?
- You'd also need to know design flow ranges, ultimate flow desired, pressure drop acceptable across valve, and the average temperature of cooling water the valve will see or the range it will see if varies much. You would need to decide if you want to use a ball valve, butterfly valve, of a globe valve to throttle the water.
- Q:my valves got dirty long story how do you clean them
- Remove the valves, wash them and the horn in warm (NOT hot) water with liquid dish soap. Dry with a clean towel, then oil and reassemble.
- Q:according to my study only indurial gate valves have both rising and non rising stem through handwheel and it seems that it doesnot apply to golbe valve and globe valves are only non rising stem. i wanted to know if this is right
- The valve in the upper left quadrant of the picture on this web page is a rising stem globe valve. This type of globe valve is common in cast steel and forged steel valves like those used in the oil and gas industry. They can be as small as 3/4 up to about 8 sizes.
- Q:Check engine light came on. Had a diagnostic exam run. EGR Valve is gone. Do I REALLY need to replace this valve, or will the car run just fine without it? 1999 Chevy Malibu.
- Nice try guys The EGR valve has a few things that makes it boath a good thing and a bad thing. First and formost it is for smog controle. The idea is that an engine requires more volume to idle than air and fuel to idle. So if you dump inert exhaust gas back into the intake the engine (pump) will not have to work as hard to suck air and fuel. Because you are replacing fuel and air with inert gas NOx is therefore reduced. In late model cars the EGR valve is actually open at various rpm levels, different engine loads, and throttle angles. EGR error codes are usually generated because of + feedback to the ECM. This could mean that the EGR is stuck (clean it), The diaphragm is leaking, (RR) or the electronics that monitor the position are fried (also a replace) Other things that can cause an EGR code are: no vacuum to the EGR valve, or plugged Exhaust gas plumbing Good Luck Does an EGR help a car warm up/ Yes but that is just a byproduct does it reduce MPG maybe but you would have to have it on a dyno to messure the change. In any event on many cars you can plug it with a plate at the intake and everything would work BUT , if the feedback from the EGR or (like ford) there is no differance in pressure mesured through a fixed orafice. you will still get an error code
- Q:For those of you that have had a heart valve replaced, why did your heart valve go bad?
- It depends on the type of the vavle. They usually get worn after 10-15 years.
- Q:Can someone please explain the difference between a pressure tap valve and a gate valve (if any).
- this will explain about a gate valve e
- Q:does anyone have a bicuspid aortic valve and wrestle? my cardiologist told me that wrestling would put too much strain on my heart but i can feel that i'm fine when i wrestle so if you have a bicuspid aortic valve and wrestle or know anyone who has that disfunction and wrestles please let me know
- I was only recently diagnosed with a bicuspid aortic valve, and before then I had wrestled for 13 years. I think every case is different though when it comes to how severe the stenosis is within the valve. If you really want to wrestle, you should ask your cardiologist if there is any way you can strengthen your heart to the point where he thinks you will be able to wrestle. Another thing you can do is try and wrestle, but pay attention to any chest pains. at the first sign of chest pain you should stop, immediately. This is nothing to screw around with.
