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: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 !
- Gas ovens, and furnaces on natural run at 3.5 inches of water column and propane is at 10.5 inches of water column. Therefore the pressures are different. If you were to run a natural stove on propane you would be eating soot, and it would end up on your walls backsplash, inside the oven etc. This is to be done only by a professional
- Q:Water has been seeping out of the sprinklers closest to the anti-siphon valve. Water seeps out of the sprinkler even when the anti-siphon valve is manually closed and not connected electronically. I opened up the anti-siphon valve to inspect the diaphragm, but there is no debris nor it was damaged. To be sure, I switched the diaphragm chamber of the two anti-siphon valves (a suspected leaky one and another good working one), but leak persists from the same sprinklers. I think the leak is from the (float?) rubber seal at the bottom of the stem closing the inlet valve. My anti-siphon is a Hardie (or Irritrol) model 311A series.1) Is my troubleshooting and logic correct? What other components could have contributed to the leak described? 2) At what scenario will water be flowing out of the anti-siphon cap?3) How can I determine if my anti-siphon valve has a vacuum breaker? What is a vacuum breaker good for?4)Which brand makes the most reliable anti-siphon valve?
- If the antisyphon valve is not leaking maybe you should focus attention on the main valve ( assuming it is a solenoid valve) to see if it closes completely. Another thing, if the irrigation zone is on an incline then the water in the system will drain to the lowest point. Sometimes it drains slowly causing the impression of a leaky feed valve.
- Q:Okay, so veins have valves to help counteract the pull of gravity. I'm wondering, do the veins in the head have this same adaptation, seeing as these veins are simply bringing blood down to the heart, and are not pulling against gravity.
- Valves counteract the pull of gravity. They also prevent blood clotting. Yes, because if they didn't, the blood could flow too fast and pool in your veins, which causes blood clots, which isn't good. So to monitor the amount of blood going through veins in the head or neck, the valves close, and open. Hope I helped. -Selene
- Q:Ive been tolding one or more of my valves is/are knocking, how can I fix this. Detail would be great, this is for a F0RD 460, from a 90. I was wondering if I can just buy some used heads(not sure if this comes with these things called valves, haha)but I can pick up some 460 heads, for pretty cheap.. on those and do a full swap, since mine is from 90 i dont know if year would matter. So how can I fix knocking valves., thanks
- Valve noise is usually caused by a bad hydraulic lifter, or a worn cam lobe, sometimes wear in the rocker arms also. I don't think changing the heads would help much in your case. I woud get a good mechanic to listen to it, and tell you first ok, because sometimes, just changing the oil and putting in an additive will stop noisy valves good luck
- Q:We have a 4 station sprinkler set-up. On the 4 station (last station to run) the Sprinkler headers are struggle to pop up water. From inside the house I hear the valve making a noise, that continues through out the entire run cycle. Any ideas on what causes these 2 problems to occur?
- Sounds like you have a valve that is not opening up fully. Is the noise coming from within the valve box or from the plumbing inside the house? I am assuming that it is coming from the valve box itself. If the valve is not opeing fully at that 4th station, the low volume of water flowing through the opening is causing a humming sound. And, with a low volume of water entering the lateral lines, your last station heads will not popup all the way, or may not popup at all. Check to make sure that you have no soft, wet, mushy areas on the turf in the last station area that would indicate a lateral line breakage or leek. If you do not see this occuring, you more than likely need to change out the valve and replace it with a new one for that particular system... Hope this answers your question. ...Billy Ray
- Q:can you spray WD-40 on it so you can turn it off?
- What kind of valve? Water? Gas? If it's a gas valve, LEAVE IT ALONE and call the gas company or a plumber. If it's water, if it breaks it won't kill you, but it can make a huge and expensive mess. First, are you sure that you're turning the valve in the right direction? When facing the valve, turn it clockwise to turn it off. If that's not the problem, then using WD-40 or other petroleum based product might work, but you have to be patient with it. Let it soak in and give it time to work dissolving and loosening rust or general grunge that might be freezing the valve. There are other products developed specifically to loosen nuts and bolts, but if you don't have easy access to an auto parts store, then try this. Spray the valve generously, wait 30 minutes, work the valve gently back and forth, spray again wait 30 minutes, work it again, etc. until the valve loosens. Don't force the valve or you'll snap it.
- Q:is it possible to check valve to piston clearance with out taking the heads off? I want to buy a bigger camshaft for my 351 windsor stock pistons with 1970 heads. cam is 230 duration (280) and 512 lift
- The piston isn't the issue here, the issue would be the valve springs. Stock Ford small block springs will bind at .500 lift, this cam will require new springs. If you don't have adjustable rocker arms (most Fords are a postive stop or torque value) you will need an adjustable valve train also. 351s and 289s BOTH use 4 inch pistons, and you CAN'T put a 3.5 inch (351) crank in a 289!
- Q:if safe, at what age should a woman with mitral valve prolapse be pregnant?
- My daughter was diagnosed with MVP at age 14. She has had 5 pregnancies, 1 miscarriage and 4 deliveries. That's 4 deliveries in less than 5 years. The obvious answer here is to talk to the OB that will deliver you to have your particular case evaluated since we don't know all the details.
- Q:Hey I was wondering how I can test the compression of the valves. Also if they are leaky. I'm thinking about valve rebuilding because my M series conn 8d was bought a few months ago and it was a school instrument. I like how it plays but I feel like there are things that should be done. The valves are one of them. So if there is any test for the valves please let me know. Thanks
- If you like how it plays you might just wish to leave it alone. Anything you do is going to change the way it plays, perhaps to something you don't like. Check compression by pulling the valve slide part way out, wait a second or two and then push the key, as the air fills up the partial vacuum cause by pulling the slide you should hear a nice thunk. If there is no noise when you push the valve the air is leaking around the valve and that's bad compression. Another way to check is just slowly withdraw the valve slide. It should get harder as you pull due to the vacuum, if it comes all the way out it should pop.
- Q:school starts tomorrow that means having band and i havent played it in 2 months (summer vacation) and i oiled the valves and the 1 and 2 valves are stuck the 1st valve comes up slowly when i push it down but on the 2nd valve it stays down how do i undo this???? thank you
- Unscrew your valve, remove the bottom valve cap, and carefully push out the valve with a drumstick or something. Clean the valve off with a cotton swab and some vinegar, rinse it off gently with lukewarm water, oil 'er up, and put her back in. If you've messed your instrument up to the point where your valve caps are all stuck from lack of cleaning, you're going to have to take it to a professional. Don't force them with a tool or anything or you'll strip them. Haha, good luck. Matt
