Q:I couldn't get a name off the valve as it sits. It has a leak on the top plate and i'd like to replace the valve plate as opposed to cutting the whole thing out and replacing.
i have seen many types of valves on an everyday basis. and i havent even seen one like this. its most likely a cheaper knock off brand valve. you have enough room to replumb a new one in quite easily. if you do not have enough room right before the valve to just cut it out, cut the pipe on the other side and unthread the valve from the threaded fitting. then buy some fittings and pipe and replumb it. you have a lot of room to work on it. i doubt you will find the same valve to part it out with. use either a Hunter valve or a rainbird valve avoid toros, orbits, weathermatic, and lawn genie parts. good luck and just take your time.
Q:Does the heater control valve anything to do with the A/C ?My heater control valve needs replacing, as it leaks when I put my truck's heat on. No heat, no leak. I have to periodically re-add Prestone every once in awhile after using the heat . I've checked the valve and it only leaks when I have my heat on, if I don't use my heat, I don't lose fluid. But now I'm wondering if I use my truck's A/C, does the heater control valve have anything to do with the radiator fluid, or just the freon? Thanks in advanceCar Mechanic in training
The heater control valve has nothing to do with the A/C.
Q:I'm thinking of buying a used 2006 Volkswagen Jetta. It has a 1.5 liter 20 valve engine, and I really don't know what that means. That's good, right?And is this a good used car to buy?
Valves are what allow the air into the cylinders and the exhaust gasses out. Cars used to only have two valves per cylinder... one to let air in and the other to let exhaust gas out, but lately cars come with more than two per cylinder. This allows the air to come in faster (with less restriction) and the exhaust gas to exit faster. Generally the number of valves isn't important, and I have no experience with Volkswagens, so I can't tell you if that's a good model to buy. Check with the Kelly Blue Book (or any similar reference book) to determine if the condition of the car and the number of miles on it are reasonable for the asking price.
Q:I heard alot about blow off valves making your engine run rich, but I want to get a blow off valve or bypass valve when I get a wrx. (I know some people think they're gay) but i dont care how loud it is, just want that sound. so what's the difference? I've been looking at this one:
Bypass Valve Turbo
Q:what is the purpose of valves such as: gate valve, foot valve and globe valve in the industry?
the valves control the flow
Q:I've been playing french horn in school for about five years, and I'm not exceptional by any means! But I love the instrument. Our school district bought a french horn a few years ago when we didn't have enough french horns for players. The almost new Holton has great tone. But unfortunately it fell into ignorant hands and has been neglected for two years. I just received the instrument and cleaned it up and got it back up to snuff, except for the valves. I can't get them to run smoothly!! They act all gummed up. I've put oil in the top and bottom of the valve, and I've dropped a couple drops in the tubes down onto the valves, but they're still gummed up! Do I need to use more oil?? Or what? Any suggestions?
Here are 3 options I know of - 1) take it in and have it cleaned. This can cost anywhere upwards from $40. I paid $75 last time. 2) Clean it yourself. Take out all the slides, pour a few drops of dishwashing liquid soap into each valve (one at a time). Get it all the way through, like you would when using oil. Use warm water and rinse out all the soap. Let it dry. This is very tedious, but has worked for me the couple times I've done it. 3) Like someone else said, use a thinner valve oil to semi-rinse out the gumminess. This has also worked well for me. Keep the lead pipe clean!
Q:Glob Valve or Gate Valve
Never heard it called a globe valve. Around here the term ball valve is more common.I have seen a few gate valves on some crew boats but that's the exception rather the rule.Ball valves are way more common. In any case,once installed on a boat they become sea cocks.
Q:It seems like the shutoff (stop) valve for the toilet is preventing my toilet tank from filling up for flushing. When I shut the valve, and open again, the water flows into the supply tube that flows into the tank for a few minutes. Afterward, the flow of water stops BEFORE filling the tank as if it lost pressure of water flow.I repeat the above (closing and opening valve) and does the same thing. (There is also no sign of leak...)What can I do? I'm hoping I don't have to call the plumber.
I think its the float in your toilet try pushing down in to the water and see if the flow begins again. If it does just readjust your float setting to the tank fill level you want
Q:HAS ANYONE HAD VALVE REPLACEMENT (WITH PIG VALVE) OPEN HEART SURGURY. WHAT WAS THE RESULTS? HOW DO YOU FEEL NOW?
my brother had it done in 1977 he chose the pigs valve because he was so young(19) and it has the most longevity. the only problem he had was alot of scar tissue developing around the attached portion and that should regularly be monitored. he lived another 11 years that he wouldn't have otherwise best of luck to you
Q:Okay so my boyfriend's father is getting a heart valve replacement....he's so nervous he cried last night when he heard it will be in 2 weeks....and he's usually one of those tough guys has anyone or know anyone who has had this type of surgery. They are leaning towards a animal (cow or pig) valve...because with mechanical you have to take blood thinners for the rest of your life...anyways if anyone knows information on this or knows the pro's and cons of the two diff. types of valves please give me info. Thanks
I have worked in the health care field as an Emergency Department manager for 12 years and had to keep up with the latest cardiac surgeries. Valve replacement is an extremely common surgery now a days. But as with any surgical procedure there are risks that the physician should explain completely until your boyfriend's father completely understands the entire process. To answer your question: The mechanical valves have been around for decades and are a proven technology. You are right, he would have to take a blood thinner for the rest of his life inorder to prevent clots from forming on the metal valve. Pros: it has a long successful history Cons: Blood thinning medication for lifeValve can wear out (after 10 to 15 years)Potentially longer recovery Conversely, the animal valves are more resilient and less likely to need replaced (although it can happen if not taken care of). There is much less need for prolonged blood thinning medication. Recovery can be shorter with less chances of strokes or heart attacks from small clots. If it were me that had to receive the valve...I would take the animal valves. Also...in some institutions (hospitals) the physicians may have the training and skills to perform this procedure through a catheterization procedure where there is no large incision in the chest. The heart valve is connected to a Stent that is inserted into the opening of the valve to be replaced--opened to cover the old valve--and left in place. The heart wall heals around the stent leaving the valve intact. I do not know where you are in the country, but many large University based Teaching hospitals can perform this procedure. I have listed two sites for additional information. Hope this helps.
