- Q: Between these two Blow off valves around the same price, what would be the best choice for a pt cruiser.
- The Mopar Performance blow off valve is really going to be your best bet if the two are roughly the same price. The reason I say that is because the Mopar unit is designed to fit onto that car, therefore it is engineered to release excess pressure at a safe level for that engine. The Greddy unit is also going to typically require modification to make it fit and function properly. Unfortunately, what they don't tell you about universal units is the reason they are universal is because they don't fit anything until you make them to fit, you just have enough material and hardware to get creative with it. If you are looking to extensively modify your engine, then it may benefit you to go with the universal unit and just wait until you have your piping cut exactly the way you want it, this may give you better location or clearance using the aftermarket unit, but otherwise like I said, I would go with the factory performance BOV. If you have any further questions about your cruiser, please feel free to email me, I have had a cruiser for a couple of years now and have also done lots of customizing to cruisers for friends.
- Q: I just dropped my 3rd valve slide from my trumpet on the ground. It fell with the curved end first. I can't see any dents and it doesn't look bent, but I oiled it and everything and it's really hard to move. Could it be bent? How can I fix it?
- Be sure that it is aligned correctly when you place it back in the valve casing. When you are putting it back in, it has to turn until you hear a click, indicating that the valve guide has fallen in the right space. This aligns the valve with all the ports. (The valve guide is a small plastic piece located under the valve spring. This valve guide must snap into a little notch inside the casing. When it does, the valve will be perfectly aligned. You will know when the valve guide is in the right place because you will feel and hear a click and the valve will not rotate any longer.) After thorough cleaning, oiling, and correct valve placement, if you still notice it sticking, take it to a repair shop to have it chemically cleaned. They are typically very good and will ensure your trumpet is in proper playing condition.
- Q: I am doing a big project on Valve and it's games. I am currently doing some research on the company and wanted to see if anyone had any interesting facts or information about Valve that may be useful when doing research, thank you. :)
- Google can help
- Q: i believe it's to do something to the valve guide to make it the right clearance n not go straight to the valve seat right? or is valve seat next?
- Once the valve guide is installed, it has to be reamed to fit the valve stem. After it has been reamed to fit the valve stem, the new valve needs to be seated in. (The valve seat should have already been done by this point) This can be done with a machine tool, or it can be ground in by hand with valve grinding compound. Once this is accomplished, the valve is removed, everything is cleaned thoroughly, and the valve is reinstalled with the spring and keeper. Normally you would do all the operations to all the valves at the same time. (That is, you don't grind in one valve, then go back and ream another valve stem. You do all the operations required at one time. So you would install all the valve guides, then ream them all, then grind or face the valve seats, then check the valve contact area, then remove all the valves, clean the head and valves up, and then reasemble into a completed head unit.)
- Q: my dad is going to go under heart valve replacement what are the chances of him surviving he is 58 years old and has copd
- It depends a lot on which valve and why it's being replaced, but unless the COPD is very bad, the average chance that a 58yo man who does not have any other major medical problems will survive single-valve replacement surgery is better than 98% if the surgery is done by an experienced surgeon at a good hospital. The COPD will very likely mean that his post-operative recovery will be prolonged and difficult, but he should do fine.
- Q: I started out playing trombone in middle school, then switched to euphonium as my main instrument. (I still play trombone for marching and jazz band, but I'm a little better at euphonium.) That being said, should I get rotary valve trombone or the one with axial flow? I only have a student trombone right now... And I have a professional Besson euphonium.
- Rotary Valve Trombone
- Q: I need to make a one way valve that would allow water or other fluid one way but if there is too much pressure on the opposite side the valve will close and stop water from flowing backward. Can anyone help?
- You are looking for whats called an RP or back flow device. These may be sold at home depot. However, I know your local plumbing supply house would carry them.
- Q: And' the valve leaks......Can the valve be unscrewed from the tank for replacement? Or can the valve be serviced with a new gasket perhaps?
- Go to the following site and enter the Model of your water heater in the box provided Click on the Magnifying glass. This should give you a list of all the parts for your water heater.
- Q: primary function of a valve position?
- ...to control flow.
- Q: I am a 55-year-old female going in for mitral valve replacement surgery, and I need to decide on which valve to get: bovine or mechanical. If you have any experiences or know anyone who's had either of these types of valves placed in their bodies, please elaborate on the experience. I want to know the pros and cons of each.Thank you.
- I had open heart surgery, repairs to my mitrial and tricuspid valves. On the mitrial valve, an Edwards Lifescience ring was placed to tighten valve and the tricuspid was just tightened. That was five yrs ago. Have more energy and feeling better, still. My surgeon did mention placing a porcine valve but once they got inside my heart, the DRs. choose the lifescience ring. I do take an anticoagulant but for other reasons for over 8 yrs now.
