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 wanted to know what is the actual difference between check valve (non return valve) and globe valve?
- A non-return valve is a globe valve with the disk attached so it can slide up and down. Back pressure will shut the valve even if the handwheel is in the open position. There will be a direction of flow arrow cast or stamped into the valve body. A regular globe valve has the disk threaded or pinned to the stem so it can't fall down. The previous answer was referring to a flapper type check valve and you can easily see by the valve body that they are not the same.
- Q:what is the difference between the pinch valve and gate valve / knife valve? If someone can help me explain / show me the complete structure of pinch valve and the way it operates, thats better
- a pinch valve has a membrane (or sleeve) inside the valve. When the valve handle is screwed down the membrane is pinch closed. This type of valve is good when the flow needs to be finely controlled. It is also good for slurry (abrasive) flows, as the membrane can be replaced when worn. Gate valves are less effective when the flow must be controlled. They are not used in slurry applications at all, as the gate will be quickly worn away. Knife gate valves can be used in slurry, but are generally totally open or totally closed. The valve must be installed the correct way around, as when closed the weight of the product against the knifegate helps seal the valve. If you have the wrong way around it will tend to leak.
- Q:My 91 GMC Van has an Idle Control Valve that is unplugged, but the van still runs great. Will the valve being unplugged, result in harm to my vehicle?
- Go to your local library, ask if they can get you the *factory* GM wiring diagram and service manual for your specific year/vehicle. They have a troubleshooting section that is usually quite good, with easy to follow flow charts. IAC is tied into the ECM in the way it handles air when you aren't using the gas...decelerating, stopping, when you start the vehicle (and different depending on whether the engine is cold/hot), etc. It will be stuck in one position now. When it starts to cause problems, you'll see them manifest in the conditions I describe above. If there truly no issues with the way it runs, then don't worry about it until you start to have problems. It's not going to destroy the motor without it. Not my cup of tea to know there is a problem, and ignore it, but then again, I'm me. You can rest assured though, if it were unnecessary, and saved GM one penny to not give it to you, they would not have installed it in the first place. :)
- Q:I threw a birthday party last night, all went well until 2am when a crazy (drunk!) lady cut all the wires from my heating system (i guess as a prank??? dunno, she is never invited back). I have everything up and running when using one thermostat and connecting the thermostat wires (red directly to tv, Brown directly to W, and white directly to T) and not using the two Honeywell zone valves (model number V8043F. How do I connect those two zone valves to the L8148E aquastat?The valves have on bottom Th-TR, TH and TR and the two top screws are labeled end switch.If you need photos I can take them :)Thanks in advance!

- Q:whaT ARE THE SYMPTON OF A BAD EGR Valve Position Sensor loss of power ?1998 toyota camry v6
- Typically when those sensors start to go bad, the EGR valve doesn't modulate properly between open and closed. When that happens you usually notice a sort of fluttering in the power delivery, often when cruising at a set speed but sometimes also when accelerating as a result of the wrong amount of exhaust gas being recycled back into the engine. You sometimes will notice a loss of power when accelerating as well. If the EGR valve is opening more than necessary it will be allowing more exhaust gas back into the engine than is beneficial....and that will reduce the amount of power the engine produces. If the EGR valve is staying closed more than necessary, you might not notice as many driveability issues but you'll probably notice your average fuel mileage decreasing a little and/or a check-engine light being triggered and/or a failure of an emissions test (even if the check engine light hasn't tripped) if you live somewhere that emissions checks are required.
- Q:just picked up my test results from cardiologist and I see it says: Assessment: 1+ tricuspid valve insufficiency and 1+ pulmonic valve insufficiency Aim 19 years old this test is a year old. (Never went back to the doc to get them until now) the reason I went back is because I feel a slight discomfort in my chest from time to time. Is not pain just discomfort that I get from walking moderate distance or lifting 20+ LB things. Please help
- Shashank has the interpretation all wrong. The information you provided us with only gives details about the Tricuspid and Pulmonic valves. 1+ valvular insufficiency means that these valves are letting a small amount of bloodflow backward into the chamber it came from. 1+ represents a mild degree of regurgitation which is normal in patients of all ages. I have it as well. If you are concerned about the chest discomfort you are experiencing, it wouldn't be a bad idea to see a doctor but as far as your test results are concerned, those results are perfectly normal.
- Q:My car (RWD) has vacuum leak and has the code PO171/PO174. I find some engine oil at the bolt well of the valve cover on the bank 2 side. Can the vacuum leak come from the valve cover? What is the main function of the valve cover? Thanks.
- First of all no. And. Second of all, to cover the valves. Little oil tubes come up to the rockers and lubricate them and the rods, springs, valve guides, top of valves. If you did not have covers than oil will spray all over engine compartment.
- Q:Where do I get a electric valve with a 120 VAC coil
- ASCO okorder is another vendor, though Grainger is good. If your budget is tight you could remove one from a dead dishwasher or washing machine.
- Q:im just bored so heres my question who do you think is better valve games (hl2 tf2 css) or bungie games (halo) and why. whoever gives me the best reson gets best answer. personally i like valve
- Personally, I find Valve the better developer. Bungie only has one series it's famous for, the Halo series, and while the same can be said for Valve, because everything is essentially mods of Half Life, Valve is much more consistent in its games. Bungie's Halo was it's first big hit, and I don't disagree with how great it was. The sequels on the other hand don't quite match up with the original. Though they're solid games in terms of gameplay, I disagree with the many reviews saying they're near perfection. The first Halo was the best of the series, possibly because it was refreshing for the genre, but the follow ups just weren't as good. Valve is one of the best developers of a first person shooter out there. They hit it big with Half-Life, and also created the opportunity for mods to arise. Mods such as Team Fortress and Counter-Strike were excellent enough to be revised, polished and sold in retail versions. While Half Life's follow up, Blue Shift, was lackluster, I think Opposing Force made up for it. Half Life 2 took a long time to make, and I think it was well worth the wait. It's own follow ups, Episodes 1 and 2 were excellent, but short. The Orange Box, however, made up for that because of everything packed in it. An excellent Team Fortress 2, the refreshingly funny and innovative Portal, and of course, three Half Life 2 games. The service Valve provides with frequent bug fixing patches is also great for those with a decent internet connection. My only complain against Valve is the steam is required to play their games, but that isn't a problem in terms of gameplay enjoyment. Halo's multiplayer communities are strong, but the same can be said for Counter Strike: Source and Team Fortress 2. This category seems like a tie. While neither company did groundbreaking things in developing either franchise, I greatly prefer Half Life 2's graphical style, the consistency of excellence and innovations (Portals, Gravity gun, fun physics) from Valve.
- Q:as we are strating centrifugal pump with discharge valve close and can not start positive displacement comp. with disch. valve closed
- No, with no discharge flow, there's no suction flow the compressor will immediatley go into surge. However, if a Low-Flow recycle control is installed, upstream of the discharge valve (which should recycle back to the suction drum to prevent heat build-up), then the compressor will operate without surging and without lifting the discharge safety valve but the condition should be corrected ASAP. (A Centrifugal Compressor will normally be fitted with a Low flow recycle system taken off from the aftercooler discharge line for use during start-up but, if a sudden low flow condition occurs and the recycle doesn't have time to activate, a Low Flow alarm and trip system will shut down the machine). Also, starting a centrifugal pump against a closed discharge is quite common practice as long as it too has a low flow protection recycle back to the suction vessel. This Low flow recycle is common where the discharge has a liquid level or flow control valve installed and may close down during normal operation. This valve would be operating as a 'Split System' controller in conjunction with the Low-Flow recycle control valve. PD pumps without discharge pressure safety protection should NEVER be started against a closed discharge, the hydraulic pressure build up will be instantaneous with possible disastrous results or stalling of the pump.
