Pressure Reducing Valve with good delivery and low price

Q: how could you make a valve or a system so that when it is pressurized, if enough pressure is reached in the system the valve will open completely and remain opened until it is close manually?I'm thinking about this in the context of an air powered dart gun, so that the firing mechanism is like a piston, and when a certain air pressure is reached, the valve that connects to the barrel will open and fire the dart: One thing you can do is get a pressure switch and a solenoid valve so that when whatever you are pressurizing comes to a certain level the switch will close it's normally open contacts and energize the solenoid which will open the valve. However as soon as the pressure level goes below the trigger level the valve will automatically close.

Q: Our water heater (bought in 2007 so still fairly new still under warranty luckily) seems to release water from the pressure release valve quite frequently. Everyone seems to say that it shouldn't do it often and ours probably does it a couple times per day. 2 main questions - 1. Is there really a risk of too much pressure building up and the water heater exploding (that's what the sales guy at Lowe's said) and 2. Any idea what the problem might be/what we should check out?: Two possibilities: When cold water is heated by the water heater it expands. In most houses the tiny bit of extra volume caused by this expansion flows back out the main line toward the street and the water pressure in your home remains constant. Some homes get such high water pressure from the utility that a pressure regulator valve is added where the water main enters the house. But pressure regulators are, by nature, backflow preventers. So now the small increase in volume from heating water results in a large increase in pressure - which is bled off by the Watts valve on your water heater. The only problem is that Watts valves are designed to operate very infrequently and only in an overpressure emergency. Yours is operating multiple times per day and functioning as a pressure control rather than as an emergency release. This can lead to premature fialure and it cn be dangerous. If you have a pressure regulator or a backflow prevention valve on your water main, ten you must have a properly installed expansion tank. The other possibility is that the Watts valve is starting to fail and should be replaced - they normally last the life of the water heater - but you may have gotten a 'bad' one. So, check for a pressure regualtor or backflow preventer and if you have you get a pressure tank, otherwise try just installing a new Watts valve.

Q: my EGR valve has gone on my Vauxhall Vectra 2.0 DI LS, 1998, 5 DOOR HATCHBACK, so i am getting a new one next week, what i want to know is, is it an easy job to replace them if so how do i do it? or is it better just to let a garage do the job?: The EGR on this model is indeed vacuum operated. The diaphragm rarely fails to be fair but that particular engine suffers with vacuum leaks. This is something that needs checking first. Also, before buying one, try sucking on the little vacuum connection going into the unit first. You should feel resistance as the plunger is sucked up against spring pressure. If no resistance is met, the diaphragm is gone and it needs replacing. If you can feel the plunger lifting, there is nothing wrong with it. You can remove it to make it easier. Push the plunger in by hand and put your finger over the vacuum connection; the plunger should stay where it is until you take your finger off. (It's hidden under the plastic cover on the top of the engine (3 Torx bolts) and is easy to access.) The EGR valve unfortunately comes with the inlet manifold (expensive) which would mean removing injector pipes etc. if you fit it all. It is, however, very easy to replace if you just remove the 2 bolts holding it into the inlet manifold. They are female Torx but an 8mm 6 point socket will work too. Any other questions on this job, just ask or email.

Q: My mom just went to DR and will have open heart next Thursday for removal of anyerisum. She was told she has 2 heart valves instead of four. What does this mean? Is it normal?: Your mom probably has a Bicuspid aortic valve, that she was born with.. it means that the valve between her heart and the aorta has two valve leaflets instead of the usual three valve leaflets (not four) in normal people. Bicuspid aortic valve is caused by fusion of two of the three leaflets. It's a fairly common congenital condition, and is associated with a risk of aortic aneurysm (a weakening of the wall of the blood vessel which then causes ballooning of the vessel wall)...usually of the ascending aorta. All the best for her safe recovery.

Q: what's the function of a car valve???????????: It is the stopper for the combustion chamber, the intake one lets stuff in and the exhaust one lets stuff out.

Q: Is it safe to remove the butterfly valve on my 94 celica 1.8l st?: Um...no Why would you want to? Also, a 94 celica should be fuel injected, and not have a butterfly valve. What do you call a butterfly valve? I call it a moveable plate that controls the air flow for the intake on a carburettor.

Q: The time has come to re shim my 06 450, and I am having a small problem (I think anyway). The exhaust valves have decreased to below the required spec and need to be replaced with thinner shims (as is usually the case), but the left intake valve has for some reason increased its valve clearance (from 0.16mm to 0.23mm). Is it normal for the valve clearance to increase? I thought they would only decrease... Any ideas? Unless the valve is being held open by something. Many thanks, Jim: The valve seats in the head take a constant pounding when the valves close - causing the valves to move up into the head and tighten the valve clearance. Carbon build up on the valve seats and valves will hold the valves open a fraction (unnoticeable in the engine's performance) - which will loosen the clearance.

Q: this question was on my test for APII, the question is stated as:the tricuspid valve is closed...a) during rapid filling of the ventricles (this is the answer the teacher shows to be correct)b) by contraction of the papillary musclesc) while the atria contractd) during ventricular contraction (this is the answer i chose i got it wrong)please let me know to correct answer!! thanks!!: The bicuspid valve is the left atrioventricular valve, and the tricuspid valve is the right atrioventricular valve. Blood enters the heart via the Superior Vena Cava (and Inferior Vena Cava) into the Right Atrium. In between the Right Ventricle and the Right Atrium is the Tricuspid Valve. The right ventricle receives oxygenated blood from the right atrium (as it contracts). Once the ventricles are full, they contract and the tricuspid valve shuts and the pulmonary valve opens. This makes sense for the tricuspid valve to shut (preventing regurgitation or backwash) while the blood flows through the open pulmonary valve into the pulmonary artery (to the lungs.) I would not have chosen a) or c) for an answer. You can rule out b) for an answer because the papillary muscles contract opening the tricuspid valve. You chose the correct answer, d) because once the ventricles are full they contract causing their respective valves to shut.

Q: my Hunter SVC VALVE will not work with my Lawn Genie Valve. Is this becaous the voltage is not matched? Hunter says it operates solenoids at 6-9 v DC // Lawn Genie says it is an 18 v DC solenoid. :-( my original Hunter Valve broke and I replaced it with the Lawn Genie. Should I get a Hunter Valve , or a Lawn Genie Controller at this point/ or is there something I have overlooked?.: Something is incorrect. All valve solenoids and all timers are designed to work at 24 v DC It should make no difference which brand of clock or which brand of valve you are using. Now the actual solenoid which is the circular cylinder with the wires coming out of it that screws into the valve may not fit all brands of valves but you can buy the correct brand to fit your valve at any irrigation supplier. If your controller is working with at least one valve it should work with any valve you have installed. I would look at the wiring and see that they are correctly installed and connected especially at the valve. If one of the two wires is loose or connected wrong then you wont get the valve to operate. If you have a voltage meter I would test it with that. If not make sure at least one wire from each valve is connected to the white (or nuetral wire) out of the controller and the other valve wire is connected to one of the hot wires coming out of the controller. If one valve does not work try connecting a hot wire off a working valve to the non working valve and test it. If it works your problem is in the wire you disconnected. I constantly work on sprinkler systems and wiring is no. one problem. Incidently I cant find a SVC valve listed in the Hunter catalog did you get the letters mixed up?
