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
♦ API STD 526 Flanged Steel Pressure Relief Valves
♦ API STD 527 Seat Tightness of Pressure Relief Valves
♦ ASME Boiler and Pressure Vessel Code Section VIII Division 1, Rules for Construction of Pressure Vessels

♦ Materials are chosen carefully , and the manufacture of the spring and the bellows has strict technological process. Each of them is tested and checked strictly.
- Q: I own a 2001 Chevy cavalier Z24 with a dual cam... Just got it tuned up and noticed oil in my spark plug sockets, which leaves me to assume either the valve cover gaskets or the cam carrier gasket is leaking oil... I would prefer to so this by myself considering I'm sure it's going to be costly.. Anyone have any ideas on how I go about replacing either?
- valve cover shouldn't be that much of a problem as long as you have some basic tools and some mechanical ability. Take it that its a 4 cylinder car, the size of the motor is very helpful when looking for tips. Just don't over torque your bolts when replacing. 89 in lbs is about normal on gm's valve covers
- Q: Need some info. Ok, four valves per cylinder is better than two valves per cylinder. Fine, why did Ford REVERT to only 3 valves (my guess is to save cost SOHC)? Audi and VW are using five valves per cylinder on some cars, does this offer any advantage over a four valve engine? Maserati even experimented with a six valve per cylinder!!!! (see link) http://www.maserati-alfieri .uk/alfier... but abandoned it (my guess is cost again?) Why are we stuck at four valves or would more valves actually render more horsepower? Pop some ideas best answer to reasonable answer...
- Think of an engine as an air pump - obviously, we want the least amount of restriction for the incoming air and also the least amount for exhausting the compressed air. The ideal situation would be to remove the head during the intake stroke and put it back on during the compression stroke, but, obviously, this isn't possible. On a naturally aspirated engine, the intake is the most critical because the air is moved only by a relatively small difference in pressures. The exhaust stroke, on the other hand, is aided greatly by the super heated temperature and rapid expansion of the gasses. Two intake and one exhaust valve seems to be the most practical and efficient solution - adding more vales means smaller valves and an increase in the overall complexity. I seriously doubt that Maserati ever abandoned ANY automotive idea due to cost restraints. It's far more likely that adding more valves than three or four simply resulted in diminishing returns. Sometimes the allure of a new buzz phrase is nothing more than a marketing ploy - a 16 valve, DOHC, four cylinder engine, for example, is a pretty impressive resume for an engine, regardless of whether it actually is the optimum performance set up or not.
- Q: i have a 8v fiat punto...is it much work to add 2 valves to make it a 16v?
- Ha...ha...ha
- Q: Also what prevents this from occuring? I have a lab due tomorrow for my biology class this is one of the questions. the answer is no where in my book, and we haven't discussed this in class. im also having a hard time finding the answer online. i would assume it would have something to do with the elasticity of the valves, and i know that when valves are weak sometimes blood can flow back into the artium when the ventricle contracts causing a heart murmur and other problems, but i haven't came across any information that talks about the valve being pushed backwards. if you can help me out that would be awesome! thanks =]
- Valves, because they open when your heart pumps and close, not allowing blood to flow backwards after the pump.
- Q: I heard alot about blow off valves making your engine run rich, but I want to get a blow off valve or bypass valve when I get a wrx. (I know some people think they're gay) but i dont care how loud it is, just want that sound. so what's the difference? I've been looking at this one:
- A blow off valve releases the air into the atmosphere which gives you the noise their known for. A bypass valve releases the air back into the intake, like a stock BOV on most turbo cars including the WRX they are also known as recirculating BOV's, and do not produce the sound that a atmospheric BOV will make. A recirculating BOV will not cause you to run rich, and thats why a lot of people recommend them unless you are running a bigger turbo/ lots of boost. However they do not always make you run rich, and i would suggest that if you do get an BOV to just install it and not mess with it. If you mess around with the spring on them it can cause compressor surge which you do not want. However, I have used the hks ssqv with none of these problems.
- Q: I have rented a house and the irrigation timer only has wires of one zone.It goes to a single valve then out to a big round cover with 6 zone pipes coming out of it. What the heck kind of set up is this?does it do a mechanical rotation inside that cover? the zones only come on one at a time but every time I turn it on I get a different zone as they are all Zone 1 on the timer.

- Q: Hi.. I was looking forward to install an electric supercharger for my 2 litre non turbo engine.This unit is driven by an electric motor instead of being mechanically driven.My question is if I can install a blow off valve in between the supercharger and the inlet manifold? Will it work?
- You don't need a blow off valve. They create only 2lbs of boost which will not get your intake out of vacume, let alone produce pressure. The main efect they have is they mix the air and fuel better for better combustion. Weisco did make a prototype that produced 8 psi though!!! Can't wait for that one.
- Q: I have an '03 vw jetta and don't know if I should get a greddy blow off valve or an injen cold air intake? Any suggestions? I don't know a lot about either, what is the difference between them?
- well unless the jetta comes with a turbo there is no need for a BOV. the CAI would be the better choice for performance.
- Q: We had a sprinkler zone that did not send much water to sprinkler heads. Checked the spring on the solenoid. We took off the top of the valve and rinsed gasket and parts below – put back together. The zone then worked. However I then noticed that the valve that does not shut off completely – water meter shows usage. I turn off water as it comes from the house.We then replaced the solenoid, the zone would not turn on. When back to the old solenoid. I switched wires at the timer and valve, it started, but when the cycle was through there still was water going through the system. Put wires back to their original locations.Space is crowded and looks tricky to replace valve. Would like advice on that for next year. However my main concern is when we shut down for the winter. We manually run each of the 8 stations and blow out the water. Will the bad valve cause a problem?
- Do you measure this 100 psi ahead of the antisiphon valve, or after it? I think you are measuring it after, and suspect the flow regulator on the antisiphon valve is not fully open. You could try adjusting it. It's also possible there is an obstruction in the piping somewhere. Any chance there is dirt in the sprinklers themselves? Also you could close down each sprinkler on a zone and see if the pressure comes up. If it does, there is no major leak. Any chance there is dirt in the spprinklers themselves?
- Q: My check engine light is on in my 1999 Toyota Camry XLE...I went to autozone and they told me it was my egr valve BUT they did not tell me if it need to be cleaned or replaced. How can I tell if it needs to be cleaned or replaced
- EGR valves are replaced much more often than they need to be. Most of the time the problem is not in the valve itself but in the EGR passages. The actual trouble code would verify that (I am expecting a P0401: Insufficient EGR Flow). The most effective approach is to remove the EGR valve, examine it for really bad deposits, then clean it with carburetor cleaner or replace it depending on whether it looks like it can be cleaned. In any case, clean out all the exhaust side passages. The second source has the usual vague ehow instructions while the third source has a more detailed but vertiginous video. EGR valves are pricey enough (typically $150) to make it worth cleaning before replacing. I personally have never had to replace an EGR valve.
