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:used in pipe line
- I assume you are referring to a pressure safety valve (PSV) or a pressure relief valve. If you have a PSV connected on the exhaust side to a relief header that can have a pressure build up in then you can use a bellows type PSV to assure that the set pressure of the PSV is not changed by any pressure build up in the header You can get a better idea of this from the first link below.
- Q:so do v-6 engines mean 6 cylinders right?, but what are valves? sometimes they are like double the cylinders (12 valve v6). what do they do, and cars that have like 2.5L does that mean how much fuel is injected and does more mean more power?on a side note, what kind of engine is the evo x? is it 4 cylinder? but has really good technology in it and is that how it has such high bhp?also if anyone knows, i kinda know what torque is but can someone explain in laymen terms? does more=better?
- OK well first, cc stands for cubic centimeters, and they measure the displacement within the cylinder of your engine. Basically, the more cc's the bigger the engine. HP is horsepower and generally the more cc's the more horsepower, altho that is not always true, especially if you turbocharge or supercharge and engine. Also, some manufacturers are able to engineer their engines better than others, thus producing more horsepower out of a smaller (less cc) engine. Finally, valves are like little doors in your cylinder. They open and let in the air and fuel, the engine burns the fuel, and then other ones open and let out the exhaust. Some manufacturers put 2 or 3 or 4 of these doors in each cylinder, with the intention of getting the gas in and exhaust out faster, thus producing more horsepower in some applications. A 16 valve engine will generally be a 4 cylinder engine with 4 valves per cylinder, it is a common engine setup. If you still have questions, wikipedia is your friend.

- Q:Would a 96 saturn egr valve work on a 96 camaro
- what approximately it? are you specific you'll be able to desire to repalce the valve itself. they could be run with the help of a sensor and vacuum traces or if sufficiently previous as yours could be basically vacuum traces. make sure your vacuum traces are good, with out holes....
- Q:My fiance needs his aortic valve replaced. He is 40 yrs old otherwise healthy. I am wondering how long he will be in surgery, how long he be in the hospital and any other info about having this surgery.
- This is major heart surgery that is done on bypass (cardiopulmonary bypass, meaning the heart and lung machine. This is very serious. He may be in the hospital for a week or more. He may need cardiac rehab to gradually be able to do simple things.
- Q:The automotive machine shop who is working on my Corolla head and block said that one of the valves was severely burnt. What causes burnt valves???
- This Site Might Help You. RE: What causes burnt valves? The automotive machine shop who is working on my Corolla head and block said that one of the valves was severely burnt. What causes burnt valves??
- Q:My boyfriend just went to his heart doctor and his tricuspid valve is leaking because of his pacemaker wire. They are saying that its moderate to severe. We are trying to decide on what moderate to severe really means. They said the same thing when he was at the doctors in June.
- Tricupsid regurgitation (TR) can be mild, moderate or severe. The tricupsid valve is located on the right side of the heart and separates the right atrium from the right ventricle. During the contraction of the right ventricle, the tricupsid valve is normally closed and does not allow blood to travel backwards into the right atrium. The severity of TR is determined by the amount of blood that regurgitates back into the right atrium instead of going into the pulmonary artery like it normally should. If a small amount of blood is regurgitated, then it is considered mild. If a significant amount of blood is regurgitated then it is considered severe. Moderate is between the two. Cardiologists frequently use the term moderate to severe to indicate that it is somewhere in the middle.
- Q:and that i need a valve job. what is a valve job, and is it expensive? i have a stock 1.6 SI motor in it, but i want to make my car better and faster, would it be cheaper to buy a new engine? some of the people who want to buy my car say that they would put a B16 vtec in it. what is that, and how much better is it than my engine?
- Basically a valve job is a valve backlash check and adjustment. There has to be a clearance measured in thousanths of an inch between the camshaft and the rocker assembly. This is generally measured with feeler guages.
- Q:The hot water shutoff valve to the washing machine was dripping. I removed the packing nut and put in new packing over the weekend. Problem is that the packing nut seems to only go back on at an angle no matter what I do...it may have already been that way though. The valve isn't currently dripping, but I'm not liking the way the packing nut only goes on at an angle. Would it be crazy to keep the existing valve if I keep an eye on it and over time it doesn't drip, or is it too risky to keep this valve given that the packing nut is on at a funny angle? (Local plumbers here in Northern NJ all want around $350 if I were to replace both the hot and cold with a watts single handle valve.) Thanks, J.
- I would do a little more trying to get the nut on straight. Turn it counter-clockwise until it drops a little bit. Then turn it clockwise. Question to ask yourself is, how long will it take you to get to the main house shutoff valve if the nut lets go? You should be able to replace just the one faucet for less than $10.
- Q:Serious answers only please. I have a 1995 Ford F-250 XL 5.8L 351 c.i. engine. My check engine light comes on periodically when I drive. When I bought the truck a year ago the gas mileage wasn't too bad, about 9-10 mpg. I've only put about 3,000 miles on it this past year, and now the needle drops just driving it across town. I work at a Chevy dealership, and I've worked at another Chevy dealer as well as a Ford. I've always done my own work on my cars and am currently restoring a 1967 Mustang, so I have decent knowledge under the hood. I scanned the truck and it has a stored code for EGR valve voltage too high (stuck open). How bad could this be hurting my gas mileage? It's $160 for the valve and sensor even after my discount, and being a college student that's a lotta $ to pay. I'm selling the truck and need it running perfect when I do. Please, serious answers only, and help is greatly appreciated!
- Open the hood, find the valve and check its operation. With the engine running, watch the diaphragm and then operate the throttle. When you gun the engine, you should see the diaphragm move. If it doesn't, there may be a dried-out and damaged rubber vacuum hose (quite likely) or else the valve is clogged up with carbon. Pull the valve out and shoot it full of carburetor cleaner to dissolve out the carbon. You should be able to move the operating diaphragm by sucking on the vacuum tube. While you're in there, start the engine without the EGR valve in place and shoot carburetor cleaner into the holes that lead into the intake manifold: one should have vacuum, and the other should have exhaust pressure.
