Application:
A pressure relief valve (PRV) is a safety device that relieves overpressure in a vessel or system. When the pressure of vessel or system increased beyond the specified design pressure or maximum allowable working pressure, PRV will be opened automaticly to relief the overpressure for proteding the vessel or system. The PRV will be closed if the pressure reached specified design pressure so that to ensure the normal operation and protect the vessel or system.
Our Pressure Relief Valve has been designed and manuractured according to following Standard:
♦ ISO 4123-1 Safety Devices for Portection Against Excessve Pressure

- Q:Hi, I was told by my gardener that I need new sprinkler valves and each of those run about $50-70. I looked up online and I found them for $20 or less. Also what is the basic labor cost for getting them installed? I got estimates that range from $300-1000. I am confused.
- they screw in and out, acouple of wrenches, a shovel, a roll of teflon tape, all less than 300$
- Q:Compare and contrast stenosis and regurgitation (insufficiency) in terms of the functional abnormality associated with the valve leaflets and their effects on hemodynamic parameters such as stroke volume.

- Q:can anyone tell me the difference between Pressure Safety valveTemperature Safety ValvePressure Relief Valveused in a process industry
- Pressure Safety valve and Pressure Relief Valve are essentially the same. When fitted on a pressure vessel they limit the internal pressure to specified limits. When the pressure exceeds a set value they open to release the pressure. Some types will maintain the pressure (Like the pressure regulator on a pressure cooker) others will release all the pressure. Temperature Safety Valves are used in boiler type of vessels containing a boiling liquid, which generates the pressure (Again like a pressure cooker). Usually there is an equilibrium between the pressure and the temperature. In such applications a temperature responsive valve is used to control the inside pressure to safe levels. If based on thermal expansion, they can regulate. Otherwise a fusible alloy just melts and releases all pressure in one go.
- Q:My doctor detectd a heart mumer. I am 48 years old. Had a echocardiogram performed. He says that I have a sightly irregular valve and I do not need to take precautions. I run three miles a day. I have heard that this condition makes your heart more suceptiable to infection. You should take antibiotics when dental work is done. My GP is a man of few words. Just says continue as usual and nothing needs to be done unless there is further symptomns. My question: Should I follow up with a heart specialist or would it be over doing it? Should I go on antibiotics when I get dental work? Can this Slightely irregular valve get worse?
- Hi not much help but i am a 26 year old female, My doc also found a mumer and then a leaking valve,said there was no need to worry this would never be a problem,but i have a history of heart disease and hypertension so I am getting a second opinion you know your body best get one to if you are concerned! Wish you the best, glad to hear i was not the only one told not to worry.
- Q:Anyone know what causes a heart valve to leak? I had surgery to repair mine (mitral) a few months ago, and now I have a very mild leak.
- The leak is called regurgitation or prolapse .. Here is a little example. Hold up your hands and put your index fingers tip to tip .. like they are pointing at each other. These two fingers will represent the valve's 'leaflets.' Operating normally, your 'leaflets' will open and close together, like a trap door. Now, within your heart's chambers, blood is supposed to flow in only one direction. It is the valve's job to ensure that blood only goes in one direction in each chamber. There are four valves .. tricuspid, pulmonic, mitral and aortic, and four chambers. In a normal valve, the sides open and close in unison with the help of regulating 'cords' that work much like a parachute's cords. If these 'cords' weaken, the valve will leak. Much like a bodybuilder that stops working out and gets flabby, these cords can get 'flabby,' (stretch) and become unable to operate the heart's valve efficiently. Sometimes, the leaflets thicken as a result of infection like rheumatic fever or endocarditis. The thickening will prevent the leaflets from closing tightly (... imagine them being slightly weighted... ) and blood will flow backwards through the valve. Aging, previous heart attacks and congenital birth defects are also common causes of heart valve disorders.
- Q:I have a question over my car. When a valve cover gasket(s) has a leak, will it still leak even after car has been off for a few days. It has also been starting to smoke after it has been on for 5 minutes. I don't move it. Thanks.
- Valve covers leak and the oil runs down the motor so it can drip off of the motor while sitting. The oil also gets on the exhaust manifold which will smoke even with a small amount of oil dripping on it. It's a fire hazard and doesn't cost much to repair.
- Q:Is there a difference between the atrioventricular valves in the right side versus the left side of the heart?Is there a different between the pulmonary valves?
- Atrioventricular valves separate the atria and ventricles. Mitral valve has 2 flaps which separates the left atria and the left ventricle, whereas tricuspid valve has 3 flaps which separates the right atria and the right ventricle. I think there's only 1 pulmonary valve, which is located between the right ventricle and the pulmonary artery. Pulmonary valve and aortic valve, which lies between the left ventricle and the aorta, are two semilunar valves.
- Q:Any way to treat the calcification of the valves?Is valvotomy only an option for youths?
- Every case and every patient is different. You could opt for a valvuloplasty or management with medications.
- Q:The check engine warning light came on in my car, i went to pump gas and try to start but it wouldn't start. I went to the dealership to let them check up, and they said the problem was the purge valve, it leaked. What is a purge valve and what does it do? Is it common for purge valve to go bad?
- i would guess on avg 100K miles. But hey, my girlfriend has a 2006 altima and the starter went bust. My 98 acura still has it's original starter (honda uses great oem parts). things go depending on driving conditions and what we in the auto parts stores call flukes. Like a 2007 pontiac that needs a new ignition coil. That's why aftermarket companies continue to make parts for cars. no one wants to go to the dealer.
- Q:I have a Chevy Silverado 2500 5.7L V8. I have been having problems with passing smog. First one failed because it needed a new cat. Replaced it and tested again. NOx emissions are off the chart (1450/1006 max of 992/59615/25mph). I replaced the EGR valve based on a suggestion. Quick test today said the NOx emissions are still way off. Suggested that I change the EGR solenoid valve and also pull the EGR valve and use a coat hanger to clean some of the carbon build up. I purchased a new solenoid today but looking at it I noticed something. Since there are what are appear to be two ports on one side of the solenoid, I must have replaced the vacuum hose onto the wrong one after replacing the EGR valve. How much would this make a difference on the test readings taken? Would it be beneficial to just replace the solenoid anyway or try to test again with the current one but connected properly?
- try changing the egr vac solenoid, and the O2 sensor. dad has a 1992, and i replaced the egr valve, the solenoid, all the vac lines, and the O2 sensor to get rid of a missfire, and help mpg. we dont do smog tests here, so it wasnt for a smog reason went from 12mpg to 15 mpg. your supposed to connect the egr to the normally closed port on the solenoid. should be the top port. there is supposed to be a bit of foam glued to the VENT port. check your check engine light codes, you can do it in 5 minutes by jumpering terminals A and B. read more about it online. code 32 is the EGR code, its the most common code on these old trucks
