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:Valve clearance importance?
- Valve adjustments are something nobody does anymore. It really is important to do to, especially if your car is older. If your valves are adjusted to tight, you can wind up with burnt valves, too much clearance and it can quickly wear out the valvetrain. BMW reccomends inspecting valve adjustment every 24,000 kilometers. You may be able to do 30,000 Maybe more than that but I personally wouldnt. It will effect mileage a noticable amout, and your car can lose power if it has too many burnt valves. If a valve is burnt it isnt seating properly and you arent getting a fully sealed combustion chamber. It is a fairly easy maintence that you can do yourself. You need a feeler gauge to check the valve lash. you will need to remove your valve covers, (you might as well replace your valve cover gaskets lest they get leaky) and find top dead center for each cylinder as you can only check valve lash at TDC. You will need a shop manual it will tell you what the measurements should be, and give a step by step method to checking your valves. If that sounds like too much work, just take it to a BMW dealer. To those of you that think that you can let it go until it makes noise.... The idea is to keep it from getting to that point. It is a relatively easy thing to do.
- Q:Does the number of valves make a difference?
- Valves let the air and fuel in and the exhaust out. Number doesn't matter much, seeing as some valves are bigger than others and overall what really matters is the bottom line which is power and efficiency.
- Q:Issue with Weil McLain water heater - Zone Valve?
- Generally, there are those who swear by and those who swear at Weil-Mclain. I am amongst the former - if installed properly and with the correct peripheral equipment. Otherwise, they can be quite touchy and very fussy. The simplest solution I can suggest is that you purchase a WM Zone Valve Control - linked below. It will be fully compatible with the rest of your system. Not so expensive and very effective.
- Q:Mitral Valve Replacement Surgery?...?
- Haven't had it done before but: It's a pretty involved procedure. Patient is put under general anesthesia and is usually on the cardiopulmonary bypass machine (heart-lung machine) since you can't really replace a heart valve if the heart is beating. mortality for full valve replacement according to wiki is 6-8 percent, prob less than 5% for young healthy patients. Recently, many people have been doing the procedure laparoscopically. Patients are put into the surgical ICU for typically 1-2 days after the surgery. You can be discharged about a week after. Obviously there's risks, this is a very involved and definitely not a simple procedure. However, the cardiothoracic surgeons do these procedures every day for their entire lives-they're very skilled and qualified. good luck!
- Q:how to check valve clearances?
- Adam S, you're both right and wrong as far as needing to adjust valves. I changed 2 shims in 100,000 miles on my Kawasaki KZ1000, but my 1300 Kaw touring bike with nearly identical valve train needs checking and adjuuting every 6,000 miles or so. Go figure. Kneedragger, since your bike requires manual adjustment, you're valve train is either going to have a rockerarm type system with threaded screws and locknuts (easy) or use shims of various thicknesses to adjust the clearance (harder). Some have the shim on top of the 'bucket that covers the valve spring. With these, you will need a small, rather inexpensive tool specifically made for your model engine to compress the spring, allowing you to remove the shim. Other engines have the shim under the bucket, requiring you to remove the camshaft to change the shim. No special tools needed here, but reinstalling the camshafts correctly is absolutely vital. While this proceduere sounds rather intimidating, just remember that checking is all that may be necessary and no adjustments will need to be made. To check clearances, the idea is to turn the camshaft to that the cam lobe is pointing away from the valve and then measure the clearance with a feeler gauge and see how that compares to the recommended clearances. On shim type, clearances nearly always tighten and if the clearance is too little, you will need to install a thinner shim. I write down the clearance for each valve each time I check the clearances. If one valve tightens up faster than the others, this will give you a heads up to a possible future problem. Or, you may find they are ok this time but at the next check, you find some that need adjustment and will decide to take it to the shop that time. After a few checks and recording the clearances, you'll get a pretty good feel for how often you need to check them again. If you decide to do it yourself, by all means, get a shop manual.
- Q:Two PVC valves?
- Leave the breather in, you need the freshair to enter the crankcase. Esentially think of the breather a the entrance for the air then it goes through the crankcase and up the other valve cover back into the intake/carb with all the oil vapors. If you wanted to run a closed system could put a line from the valve cover with the breather to the air cleaner.
- Q:aortic valve stenosis severe amemia hemoglobin 9.1 ?
- I don't know of there being any relationship. The only thing would be if your aortic valve was damaging your blood cells, but I don't think that is the cause of your anemia. I wouldn't call 9.1 Severe. It would have to be below 8 before anyone should consider giving you blood. I work as a nurse in a hospital and have seen tons of Hemoglobin levels in the 7's and 8's. I've seen a few 5 and 6's. So don't get too worried about how low it is, just keep looking for the cause and treat it that way.
- Q:What is a flow valve?
- sophisticated situation. look on to yahoo. just that can assist!
- Q:i wanted to know what is the actual difference between check valve (non return valve) and globe valve?
- Check valve/non-return valves are unidirectional, meaning flow can only go through them one direction. Check/Non-return valves usually don't include any kind of manual actuation. Globe valves have a sphere with a hole cut through it, as the globe is rotated within the housing, the hole aligns with the valve inlet and outlet, or is sealed from the inlet/outlet by the valve casing. Thus, the handle/knob is used to rotate the ball, thereby opening or closing the valve. Because the hole is cut cleanly through the ball, flow through a globe valve is bi-directional.
- Q:chevy 350 exhaust valve seat pittings?
- hard to tell looking at your pic,s. your best bet is to find a trust worthy machine shop...they can tell you if they can be lapped or if they need replacing...newer heads have hardened valve,s seat,s..if damaged they should be replaced ...valve,s , seat,s , guide,s , valve seal,s , possible rocker assembly,s , lifter,s , push rod,s ,Etc......best of luck!
