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: wut is the purpose of this valve on tanks and on piping? explain wut the vacuum part does and wut pressure does? thanks
- The pressure relief valve is to protect a tank or piping from rupturing from excess pressure. A vacuum relief valve would prevent tanks and piping from collapsing from too little internal pressure.
- Q: Last year an echo revealed severe aortic valve regurgitation with low ef of 37 but ecg was normal. i am 36 yrs old. I have noticed that i often have chest pain when i lie on my left (especially after a heavy drinking or if my bp is high) but the pain subsides when i lie on my right or back. Is it possible that my aortic valve only leaks when i lie on my left side, if so, can I continue living a normal life without needing valve replacement surgery if avoid lieing on my left side. or i'm i fooling myself, is the heart damage progressing silently?
- Hello, You don't tell us *why* your doctors think, you developed this problem with your aortic valve in the first place? Has there been any infection of the valve with germs, (bacterial endocarditis)? Did you have Rheumatic Fever as a child? Were you born, with stenosis or regurgitation of your aortic valve? Do you have abnormally early, clogging-up of your artery-linings with cholesterol?
- Q: I would like to know about the signal pneumatic valves are drivesn (PWM,PCM?) and about their bandwidth and bit rate. Where can i find info?Thanx!!
- Go to the FESTO website. they should have all the answers for you in the downloadable litriture.
- Q: So I know the main purpose of the EGR valve is to recirculate some exhaust to the cylinders to reduce NOx emissions. However, a mechanic told me that a malfunctioning EGR valve can make the engine run way hotter, and that this can damage the pistons, or other components of the engine, over time. Is that true?
- Yes. An EGR valve reintroduces exhaust gas to cool the combustion chamber, making it run cooler, due to less oxygen. Oxygen burns hotter than fuel. So if you have a faulty egr valve, emissions will go up, and you run the risk of overheating and damaging the engine. It could cause the pistons to expand, or seize, due to higher temperatures. It was not as much of an issue in yesterdays cars, because they had much lower compression. Now tolerances are tighter, but metallurgy is also much better. It still does run the risk of running hot, and causing predetonation, which would destroy pistons and other engine components such as the crankshaft, and valves.
- Q: When i went to the cardiologist a few months ago, i remember him saying that my pulmonary and tricuspid valve were leaky, and i think he said they were a 1 on a scale of 1 to 4 which is minor and of no concern. but i have valve problems in my family and i got thining about it. anybody know what this scale is called/have more info or was it something he just made up to tell me that it was minor?
- Initial auscultation of your heart sounds can determine the presence of murmurs which are indications that valves are not closing properly (leaking) and allowing the heart chambers to fill and empty properly. Usually once murmurs are detected, an echocardiogram is done to visualize the valve function. From this test gradients can be determined to assess individual valve functions. The higher the gradient (it's a calculation based on blood flow and pressure across the valve leaflets) the worse the valve function. Mild gradients are not considered serious and are usually just monitored with your regular checkups to see if they are worsening. Serious gradients indicate poor valve function and are usually corrected with either valvuloplasty or valve replacement. Serious valve impairment also has associated heart symptoms such as congestive heart failure, left ventricular hypertrophy, arrythmias, and poor ejection fractions-to name a few. Regular follow-up is suggested with your cardiologist to monitor any potential deterioration in your valve functions. Meds are often used to treat the symptoms of poor valve function not to cure your valves. Once damaged, heart valves do not repair themselves. The aim is to reduce the workload put on the valves and prevent their function from declining further. Hope this helps.
- Q: I mean dropping the valve seat. And some mechanic told me that it dropped when the catalytic converter got clogged and it hurt the engine. But the most I've heard is that if I want to avoid this from happening I should be running the engine a bit colder because the valves weren't made with the right specs and after a 100,000 miles they become a bit loose and when the engine gets to the normal temperature or just a bit above, the valve seats would drop. Does ANYONE KNOW ANYTHING ABOUT THIS?
- Those old escorts ran forever. I don't fully understand your question. Are you having any problems with the engine now? If the engine is running like it always has, I think you are worrying about a stray comment from a mechanic. If one of the valves seats moves out of position, you will know. The engine will start making ticking sounds and you may lose power. If none of that is happening, you are worried about nothing. If you are having some of those issues, then take the car to a competent mechanic have the problem diagnosed and get the head rebuilt. It's not that expensive on that engine. Then you will have new valves, new seats, new guides and a very clean head.
- 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: Can a clogged EGR regulator valve cause my car to stall out and die when it's idling at red lights?If I give it a little has it wakes the car up and keeps it from dying.One mechanic told me it was clogged up and that it can cause that issue. My boss says there's no way that's the problem... I say we've fixed cleaned or replaced just about everything else...Is this true or is the mechanic just trying to pocket a bit more $$??
- No, there is no way a clogged EGR valve can cause the car to stall. The EGR valve is only supposed to open and allow flow when the engine is under load so if it's flow is stopped all the time it behaves no differently at idle than a new valve. HOWEVER, if the valve is dirty or carboned up and the valve is getting sticky and not closing all the way when it's supposed to then it can cause a stall. Do you know what kind of car it is? Update: It's a 2002 ford focus wagon These cars have a very common problem with stalling and it is usually caused by rotted out rubber elbows on the PCV valve vacuum lines. If you follow every inch of the PCV hard lines there will be at least two rubber fittings on either end of the system, poke your fingernail into the corners to see if they have gone soft and cracked.
- Q: where on the motor is the valves location
- The idle air control valve can be found under the throttle body. In order to get to it: 1. Disconnect negative battery cable. 2. Remove air intake from throttle body. 3. Disconnect throttle body cable. 4. Disconnect sensor connectors from IAC valve, and throttle position sensor. 5. Remove 4 bolts from throttle body using 10mm socket wrench. 6. Take throttle body, turn bottom side up, remove 4 mounting screws from IAC Once you do that you have removed the IAC. Reverse the steps to put it back on starting at number 6 and working your way back to number one How do you replace an air idle control valve? Replacing an idle control valve can be a daunting task. For your specific application, we recommend to ask in our car forum for advice. Here we will describe the basic process for replacing your idle control valve. Please note that for different cars and trucks the process will not be the same. Steps to replace your idle control valve You will want to begin by first gaining access to the idle control valve. In order to do this you will need to remove the air filter assembly, along with the air mass sensor and the air mass meter boot. Once you remove this whole assembly, you should have easy access to the throttle body. Remove the four bolts that secure the throttle body to the intake manifold. Usually on the bottom of the throttle body, on fuel injected cars, there is a idle control valve. To remove the old valve, simply unscrew or unbolt it. Bolt on the new valve, and reinstall everything. Make sure you replace your throttle body gasket at this time.
- Q: like they say on 4 strokes you gotta go get valve jobs, and they cost bout 300 they say? well what does the mechanic do? can it be done at home and your just adjusting them?
- i'm 18 and race a crf40r i admire the motorbike. in case you desire to flow extra decrease priced i might decide for 2 stroke. have faith it or not 2 stroke is extra maintence even though it is lots extra decrease priced to rebuild. A 2 stroke on long tracks with enormous sweapers is purely as speedy as a 450 if not speedier. I enjoyed my 250 haha. 450's are somewhat a combat on the song they supply a real undesirable arm pump by using engine breaking. and 250 4 strokes are like driving the previous one hundred twenty five's all you do is shift. in case you may desire to get an rm 250 2 stroke they have the extra appropriate potential bands and have very solid bottomw end.
