Q:01 civic valve question?
1.7 SOHC VTEC? I thought that used hydraulic lifters with the small flat plates under the lobes like a subaru or the DOHC older style hondas no? Otherwise i've never adjusted those valves unless they are the same as my old engine like a 1.6 SOHV ---V for valves Where you adjust the top screw and loosen the nut then adjust with the guage. Question are you useing the manual while adjusting from Honda? You can't just take the valve cover off and start sticking the feeler guage at every spot, Do know where each piston is at and at what stroke? also don't get the adjustment wrong for EX. and IN. side because that will just mess everything up even more. Is it high mileage also? and if you know you did it right and it still sounds loud you might have a bent valve or just engine damage like piston slap or something else. I've never had to adjust the valves for that vehicle in all the years i've worked on hondas or acuras, even though they say to adjust every 100k or something we've never had one that was really loud in that model plus those engines are dirt cheap and easy to swap if any engine damage is done... But ya, the honda manual is best for step by step instructions specially when you have to check certain ones at certain piston positions and after you can learn a trick to do it even faster and you can check a few at the same time then turn the engine and check the other ones but theres not enough space to explain in detail if you don't know.... Good luck though....( and do not leave the guage under the valve while your tightening the bolt down, you will squish the guage and then your specs will be off to )
Q:what does a Pneumatic valve do in a process?
pneumatic valves use pressurized gas (Air, nitrogen) to operate.A simple example if you are monitoring the level of a vessel in a process the indicator for level (LI) tells you remotely what the level is. If you need to keep the level stable the level indicating controller (LIC) sends a signal to the regulator on the Pneumatic Valve which provides air to open or close the valve depending on what the vessel level set point is. the FIC (flow indicating controller) PIC (pressure) TIC (tempurature) are all instrumentation used to compare a set point parameter against a measured process variable and send a signal to control the valve to maintain the set point
Q:Where can i find a three-way air pressure valve?
You might have to register on the site to order online. It is free. You can call them and order the catalog. It is free also. Hope this helps Email me if you want me to look it up in my catalog. Don't break any windows. Wingman
Q:Anti-Siphon Valve leaks = Where??
I work in a printing plant,and our city mandates anti-siphon valves on all our commercial equipment,so I have a little knowledge about these.We used to call these pesky creatures Vacumn Breakers,but now they are called anti-siphon valves,but what's in a name-they both are supposed to accomplish the same thing.Should your water pressure drop,due to a broken main or largefire,these devices are supposed to prevent contaminated water,like the contents of the Agfa Encomatic plate processor rinse tank,or your irrigation pipes,from being pulled back into your plumbing ,and then out your faucets when pressure is restored ,which could make everybody sicker than pooches. The way these work on industrial models is a little more complicated,but the principle is the same,for water to flow through the system,a certain pressure must be maintained.Our older models had a spring and diaphram arragement,the water pressure pushed the diaphram against a seal seat,with a spring behind it.As long as the pressure in the valve was greater than the spring,water would flow through the vave,but when the pressure ceased,the spring closed the diaphram,which in turn opened a vent that allowed the water to drain hence,vacumn breaker.These had to be at a point above the turn-offs,by the way,and when they malfunctioned,due to debris or rusted springs,they could either fail,and stay open,or fail,and water wouldcome gushing out the cap. The conditions you desribe sounds like a low pressure situation,where there is not enough pressure to flow through the anti-siphon.Is your supply line kinked or crushed?
Q:Trumpet valves sticking help?
Check that you are not putting sideways pressure on your valves when you press them downwards. Even on a good horn this sideways pressure can cause friction between the piston and the valve casing. Avoid this by arching your fingers a little, depressing with your finger's tips, and avoid the pinkie finger ring entirely. Tying your pinkie up in that only restricts your 3rd. finger's freedom of straight downward movement. Over- lubricating the valves can be as bad as too little oil. Do the whole warm bath treatment that you would normally do to clean it, add 3 drops to each valve, work horn for a few minutes, wipe valves with very old (washed heaps of times) t-shirt: then finally 2 drops again. If this doesn't work, get a trumpet specialist teacher to take it home for this treatment.(You might not be bathing it right). Failing that, check my web site's repair section. Good Luck!
Q:How do I fix a leaky brass gate valve?
Creative, While those valves are open, you certainly could try to snug up those smaller brass nuts up on those gate valves just below the handles. That might stop those leaks. If you find that you can't tighten those up anymore, there's nothing else you can do but replace them. Those are gate valves it looks like they are either 1/2 or 3/4. Those valves have female iron pipe (FIP) union-like fittings on each end. There are lots of different types, styles, sizes of gate valves. There are countless ways to replumb what you have there but, if you want to try to make it as simple as possible and just replace those valves, the thing to do would be to shut the water off, disconnect one of those valves, take it to a good plumbing shop and have them spedcial order THAT SAME VALVE! (3 of them) Because you want the exact same thing. (This would be the easiest way). By the way those gate valves that you have are not common ones. They are unusual because they have those union-like fittings at each end. You won't just be able to find those easily. That's why they will more than likley have to be special ordered. Good luck
Q:pool and spa valve diagrams?
You have one or more faulty valves or you've got them turned the wrong way for the operation you want. You also may have a check valve that's going bad. The problem is that I'd have to see the setup around the pump and filter to even get an idea of what goes where. My pool has electric activators for the valves that allow automatic operation from inside the house. I adjusted one incorrectly once and it activated the valve backwards, and I had to readjust it.
Q:Tire Valve Stem cracked?
Any reputable tire shop will install new valve stems when mounting new tires. This really sounds like somebody is messin with you. Anyone else in your area having similar problems?
Q:aftermarket blow off valve info?
Don't do it. First of all, if you knew enough about turbo charging or supercharging, blow off valves, bypass values, hooters, etc., then you would have known we need to know the size of engine, model of turbo, piping diameter, etc. The actual control lines are not that complex. By using your tongue you can tell what each line is ported to, and then you just need to know if you blow off valve is operated by vacuum or lack of vacuum. They make both types. And your throttle body will have ports on both sides of the plate. And yes, it does very much matter. Turbo charging is not for the novice to fool around with.
Q:Fast fast question about aquarium check valves?
The airstone is not too big, unless it causes the water to bubble right out of the tank. Then you will need a valve to divert the excess air to an unused air line. If the airline is already cut, just put the check valve wherever the airline ends. If it's not cut you can put it anywhere. The arrow on the check valve should point toward the aquarium. If it says IN and OUT, then the OUT is on the aquarium side. If you want to test it to be sure, blow in one end of the valve. You can't blow air into the side that connects to the aquarium. Be sure there is a drip loop in the air pump electrical cord. If water were to somehow get in the air pump or drip on it, water might follow down the outside of the electrical cord and go into the the wall outlet. To make sure that doesn't happen be sure the cord is looped down lower than the outlet and then loops back up before it's plugged in. Get a second airstone any time in the next few weeks. About once a month, trade airstones, putting the recently used one into a jar with white vinegar. A week or so of soaking will unclog the airstone so that it can be used again several times before needing to be discarded. If you do have excess air, I find that running a piece of airline tubing to a spot away from sight and putting a short piece of pipe cleaner in the far end will muffle the hissing sound of the excess air.
