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: From searching around I feel that I need to replace this on my vehicle. Is the Suction Control Valve different from the Idle Control Valve? Sometimes at a stop light the engine will stall. A couple times it has happened while driving when coasting to a turn or stop.
- hold the computer near the Pathfinder it will suck data directly off the internet (NO WAY) what you need is a complete diagnosis by a experenced Technician or a Nissan Technician. Idle control is on the bottom of the throttle chamber or on the intake manifold. Stalling and Dieing may be caused by a Distributor or air flow meter fuel pump or clogged up fuel filter. Suction control valve in not a part on your year pathfinder good lick
- Q: Grade seven, my teacher's a pain. She didn't even explain the 'sets', we just know what valves are in general. So.. which set of valves closes when the ventricles contract? Relax? Thank you so much!***10 POINTS***
- Atrioventricular valves close when it relaxes and the lunar valves close when it contracts
- Q: can a person survive with only one heart valve functioning?
- Biological valve is made of human or animal tissue. These valves last 12 - 15 years, but you may not need to take blood thinners for life. Human body has a tendency to reject foreign material such as porcine valve. Medication can be used to retard this effect, but is not always successful. Biologic porcine heterograft - harvested aortic valve of pig that is preserved in glutaraldehyde and mounted on specially designed sewing ring.
- Q: had a water heater put in after that i have low hot water pressure it get hot but goes to a low stream.when i try to adjust gate valve it keeps turning
- A gate valve is used as a shut-off, not a regulator. It is supposed to be either all on or all off, and the handle only has a total movement of 90 degrees. When the handle is aligned with the pipe, it's on, and when the handle is perpendicular to the pipe it's off. If the handle is turning more than that, it's broke and needs to be fixed or replaced.
- Q: What are the benefits of changing new cylinder heads and exhaust valves in the Main engine of the vessel? I am now studying a vessel which has a problem with their main engine. Frequent repair of cylinder heads (they usually weld it) and exhaust valves are the ones they do. I need to further give the benefits to be submitted to the vessel's management for them to buy new cylinder heads and exhaust valves as a replacement for the welded ones.
- It sounds to me like this ship has an ongoing exhaust problem (maybe an obstruction of the flow) Or a low volume of cooling water (look at the water pumps) About the only reason to weld a head would be because of a crack and the most likely reason for a crack is over heating likewise the burned valves! Assuming that the engine was assembled correctly What else would cause the over heating except one of the above! Before you put new expensive heads and valves on this thing check out the over heating ( just because the Gage never shows hot dose not mean that it isn't! If the welding and the valve replacement was done correctly then there may be no benefit at all in buying new ones a compression test would tell,but a REAL LARGE benefit in finding out WHY this would happen especially more then ounce !
- Q: 1990 Pontiac Sunbird, I took a piece of hose going to the egr valve to try and see if it is working properly, but with car off, I can suck through, and blow out into hose going to egr valve, and it doesn't seem like there's any seal stopping air flow either way...is it supposed to, or what is this supposed to do?
- The okorder /
- Q: I'm taking a pipe fitting class and I can not find witch valve had the most restriction.
- VALVES CAUSING RESTRICTIONS? WTF? When they are CLOSED or not open all they way, they can cause a restriction. Otherwise, in and of themselves... valves do not cause restrictions.
- Q: If someone is not born with heart valve disease... can a teenager or a 12 year old develop heart valve disease?
- If a teen has heart valve disease, is most likely something they where born with, but it can go undiagnosed till the are teens. I was born with aortic stenosis, aortic regurgitation, bicuspid aortic valve(all are valve disease) and i also have an enlarged aorta. Im 16 years old. I was born with the bicuspid aortic valve and aortic stenosis, and that caused me to develop aortic regurgitation when i was 10, and an enlarged aorta at 14. In some cases a teen can develop it with out being born with it, its uncommon but it can happen.
- Q: what is the purpose of valves such as: gate valve, foot valve and globe valve in the industry?
- Valves are used to stop/start or control the flow of liquids or gases in pipes. There are many many kinds of valves, so if you want info on a specific type, just list that.
- Q: this question was on my test for APII, the question is stated as:the tricuspid valve is closed...a) during rapid filling of the ventricles (this is the answer the teacher shows to be correct)b) by contraction of the papillary musclesc) while the atria contractd) during ventricular contraction (this is the answer i chose i got it wrong)please let me know to correct answer!! thanks!!
