Q:what does a vacuum switching valve do?
Vacuum Switching Valve
Q:Double valve air pump?
If the pump doesn't come with any method to shut off one of the outlets, you can combine both outlets into one by using some tubing and a T-valve. You can also use an air valve and some tubing on the unneeded outlet to dead-end it, though that method may be a bit more stressful on the pump.
Q:Is it possible to re-port a globe valve?

Q:How much for a valve job 96 Camry???
A valve job is removing the cylinder head(s) from the engine so the valves, guides and seats can be refurbished to restore compression and oil control. A valve job may be necessary by the time an engine has 80,000 or more miles on it, or to fix a burned valve, compression or oil burning problem. If the valves are to be reused, they will be inspected, checked for straightness then refaced. Many shops automatically replace all the exhaust valves to reduce the risk of failure (exhaust valves run much hotter than intakes and are much more likely to fail). On the other hand, if you have an import car with dual overhead cams, four-valves-per-cylinder and a lot of fancy valvetrain hardware, you might be looking at a total bill of $200-$300. Parts typically cost much more for import engines as well as performance engines and diesels. The labor to do the valve work is also much more involved on these overhead cam multi-valve heads. (Of course, they didn't tell you that when you bought the car. All they stressed was the fantastic performance of overhead cams and multiple valves.)
Q:Where is this pcv valve?
It should look something like a flattened top and should be black and in line with your fuel fline to the injectors.
Q:Do we need to position a Gate valve as per the flow direction?
the gate valve is a very important one in flow measurement and also used to help the measure of flow. for example if you know the pneumatic comparator operation, you can easily under stand the gate valve. the gate valve is mainly used for to adjust the float in the tube to zero position or the clearance value.
Q:Unplugged Idle Air Control Valve?
Won't hurt a thing.
Q:97 Neon - Canister Purge Valve?
Could you describe this canister purge valve? Not sure what you are talking about here. Is it part of the emissions, part of the radiator, or what. I am just guessing it's part of the emissions. In which case, I need to know if it has a smog pump. Could be the pump, could be a clogged up cat, could be a bad EGR valve. Need some more info to help beyond this point. Good luck.
Q:What do people mean when they say they have a 12 in valve?
A 12 inch valve means it is designed to fit with nominal 12 inch pipe. Most 12 valves are flanged so these valves would also be flanged to match as 12 piping flange. They would also be sized to match the appropriate flange rating as in 125#, 250#, 150#, 300# 600# and so on. As to the opening of the valve that will vary depending on the type of valve. For a gate valve it will be very close to 12 inch in diameter. For a globe valve it may be a bit smaller. In some cases you will see what it called a reduced port valve where in internal opening is smaller. This is more common with large ball valve where the smaller ball and opening makes the opening/closing torque less. These valves also tend to have a venturi shape on the inlet and out leading to be ball so the pressure drop is closer to a full opening valve.
Q:Laundry room hot water valve leaking?
Not to sound insulting but the hose will have water left in after you turn the valve off , use a bucket and drain the house before you go tearing things apart. You really do not have to change the whole valve if that is the case, there is a rubber washer inside of the valve which may be worn or distorted from over tightening of the valve.Either way you have to drain the system I would tell you to attend one of the plumbing classes at Home depot to learn what to do they hold them all of the time .
