Q:I got new sprinkler valves put in (Rainbird anti-siphon kind). Every time a valve shuts off, it makes a loud squeak, kind of like plastic rubbing (NOT a bang like water hammering). Is this normal and will it go away? If not, what could be the problem? This is annoying because the sound can be heard in the house as it echoes through the pipes.

Q:My 97 Tahoe has a leaking A/C pressure valve. I went to charge the system yesterday, and when I finished I took the hoses from the charging gauges off. The pressure side valve leaked. I pressed it down with a small screwdriver yet still couldn't get it to seat. I looks like it might have a damaged seal around the valve.Can I replace the valve? And if so, how. Or do I have to replace the entire hose assemble as they connect to the compressor?Thanks

This is a very common problem and you will need to reclaim the freon and replace the service port only and not the hose, however you will need a special socket to remove it or you will damage the hose as well as the new valve......... After you are finished you will need to evacuate and recharge the system complete and dont for get to add refrigerate oil back as well.

Q:i have a 1996 doge grand caravan,do i need to lower gas tank to remove rear proportioning valve for my brakes, it leaks fluid and is in a bad spot to get too ?

i got a 97 model van setting out side the shop and i went and looked at it and it doesn't have one on it,what are you calling the rear proportioning valve,it has a block that the lines split off of but not a proportioning valve,let me know if you got some kind of special edition or something,good luck.

Q:i have a yamaha trumpet. i got it brand new and it is 3 years old. I recently did drop it and i have a tiny dent on the last turn to the bell. after that they started sticking . There are no dents on the valves or casing surrounding them. i brought them to Quinlan and fabish and showed them the sticking they replaced the valves spring padding and the such. They also did an ultrasound cleaning i think it is called . they are still sticking. Please any think that you can suggest i showed my band teacher who suggested going to Quinlan and fabish. Then my trumpet teacher who said i need to oil more after the cleaning please 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:Im replacing the valve stem seals and i dont know how to remove the springs and with the valve compressor wont fit in the engine

Do NOT do what banit said, if you did his technique once you remove the keepers the valve would drop to the bottom of the cylinder and require a tear down. You must get the piston be at top dead center on the cylinder you intend on removing the valve springs from and you cannot do any other valves besides the ones on the cylinder you brought to top dead center. You can take the rocker arm off the top and take the push rod out then when at top dead center using a spring compressor you can take the keepers out, or if you do not have a spring compressor (proceed at your own risk) you can get an oversized socket and a dead blow hammer and place the socket over the top of the valve spring with the octagonal side towards the spring and give it a decent hit, but be aware the keepers will pop out and you may lose them if you are not careful.

Q:how to reset control valve with electron pneumatic positioner of (make) Instrument and system.?

Control valves come with a spring g which keeps the valve in either the open or closed position, when there is no air pressure applied to the diaphragm of the valve actuator. For this reason, I'm unsure what you mean with 'reset the valve. The electro/pneumatic positioner is a device which applies the air pressure required to open (or close) the valve to the position the electric signal from the controller is calling for, rather than using an I/P transducer to output a 3 to 15 PSIG air pressure to the diaphragm. Sometimes an actuator requires more pressure than the normal 3 to 15 psig to move a sticky valve to the correct position. Edit your question to detail what is occurring, and I or someone else can give you a proper answer. TexMav

Q:this valve uses in fire water lines...

Deluge valves are used in special fire sprinkler systems. Open sprinklers or spray nozzles are attached to piping and to the valves. The valve is connected through control valves to a water supply system. The deluge valve consists of a housing, a swinging clapper like an ordinary check valve and a retractable keeper to hold the clapper tight to the valve seat. Electrical pneumatic or hydraulic mechanisms can retract the keeper, causing the valve to open. Other attachments provide for alarm sensors, gages and the like. See one at the link below

Q:how do u remove a valve seat from a head, and install the new one?

What engine? Not all heads have valve seats that are pressed in. Some (many later model cars) have the seats ground right into the head and are not removable.

Q:I dont want to buy an expensive snorkel, because I only want the valve. Its for a project for a club where I go to college.
