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

♦ Tightness: conforms to API STD 527
Features:
♦The solid nozzle is screwed into the body, which makes the maintenance easy.
♦ The shape of the disc holder has been designed to enhance the effect of the fluid thrust for an instant lift of the disc.
♦ Blowdown control is provided with adjustable nuzzle ring only.
♦ The adequate terials and clearance between disc holder and guide , spindle and adjusting screw assures disc to lift successfully.
♦ The surface of both the disc and the nozzle seat are deposited with Stellite. Excellent flatness and surface finish of the seating surfaces by precision machining and lapping assure pressure relief valve to have high degree of seat tightness and long using life.
♦ The bellows of balanced bellows pressure relief valves can not only avoid and effect of variable back pressure in the system , but also protect spring and other trim components from corrosive media.
♦ 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: The tricuspid valve is closed: a. during the rapid filling of the ventriclesb. when the mitral valve is openc. during ejection of blood from the ventriclesHelp plzThank you!
- b, when the ventricle contracts the valve closes to prevent blood from moving back into the atrium.
- Q: When I flush the toilet it flushes just fine, but it doesn't fill again. You have to close the wall valve and then open it up again to fill the tank. Is this a problem with the valve or the internals of the tank? Thanks
- Check your fill valve (inside the tank) first. If it appears to be working properly, turn the water off outside the house, drain the tank, take the filler tube ( from the valve to the bottom of the tank on the outside) loose at the valve. Remove the valve and inspect for obstructions, such as calcium and or lime deposits. You may need to replace the valve as they will occasionally wash out over time. Reverse this process to put everything back together, and be sure to wrap the male threads on the supply line (pipe sticking out of the wall) with teflon tape.
- Q: 2003 Ford Focus SE2.0L SPI EngineAutomatic Transmission 145KPerfectly maintained since new!One of the pistons had snapped, yes the actual piston, it didn't mess up the walls, but I am hearing a LOT about these dropping valve seatsI intended to do an entire rebuild with a kit, but did it break BECAUSE of a droppedvalve seat?I don't know because I don't know what that isHelp is appreciated
- highly unlikely , depends how the piston is broken often when revving too high the piston top will separate at a ring groove nothing to do with valve seats
- Q: my dad is going to go under heart valve replacement what are the chances of him surviving he is 58 years old and has copd
- It depends a lot on which valve and why it's being replaced, but unless the COPD is very bad, the average chance that a 58yo man who does not have any other major medical problems will survive single-valve replacement surgery is better than 98% if the surgery is done by an experienced surgeon at a good hospital. The COPD will very likely mean that his post-operative recovery will be prolonged and difficult, but he should do fine.
- 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: 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?
- You aren't getting a lot of power out of a BOV. I don't mean to sound obvious or degrading if you know this but a BOV makes the pissssssss sound you hear when you wined out the turbo. It might help the turbo release some pressure and get some more power that way but besides that not much. You will spend about $250 on a blow-off value and unless you install it it's gonna cost you about $80 per hour to have someone else do it. It is about a 1 and 1/2 hour project so your looking at $370. An air intake on the other hand is what I suggest. To get a brand name it will cost about $250 but you can install that yourself in about 45 mins after figuring out that you have been reading the directions upside down for the last hour. Just kidding... It's a really easy install and it can add anywhere from 10-15hp. By the way, if you don't have a turbo Jetta there is no point to buying a blow off value because it won't do anything. Now that I think about it if you do have a turbo jetta get a DV (Diverter Valve). The nice thing about a diverter valve is that it will prevent you from losing boost which is what gives you most of your power from the turbo.
- Q: Why would oil be leaking from a blow off valve?i own a 05' gti 1.8t, i have had the blow off valve for about a year now, its a HKS SSQV, but i just revently noticed that when it blows off, there is a spray of oil that comes out..... why would it be leaking oil through the blow off valve? i know VW dont really go well with blow off valves, but it hasnt given me any problems until recently....
- I'm having a very similar problem, i'm thinking the turbo might be damaged and leaking oil.
- Q: I was diagnosed with a VSD and a Biscuspid Aortic Valve and my doctor has started hinting towards sugery. I found out that the only reason i haven't had surgery yet is that it is stable enough to wait until technology improves so i am not left with a large scar. i was just wondering what this surgery would entail and if anyone has had it. I am 19 years old and kind of worried about it...
- VSD or ventricular septal defect is a congenital disease caused by failure of your ventricular septum to fuse with the bulbar ridges of your atrial septum during embryogenesis. Some VSD are fine since only a small amount of blood is shunted from LV to RV but a majority is still shunted straight to the aorta. An aortic valve stenosis which I think is what you are referring to is usually an adult disease associated with rheumatic fever, mechanical breakdown from hypertension, or death from an MI. Aortic valve stenosis is a bit more worrisome since this can lower the output of your heart by acting as an obstruction, which overtime can cause ventricular hypertrophy, a disease with whole set of other problems. New trends in VSD repair uses minimally-invasive surgery using a transcatheter that is inserted esophageally or through femoral artery; very small scars and short recovery time. Aortic valve repair may also be done this way in the future, but if your aortic valve is still patent, there is no need to replace it at this moment because it would require a donor and open heart surgery.
- Q: .The valve behind the toilet is spewing water (we have connected a hose to it and have it emptying into the tub). When we try to shut the water off from that valve, the knob or turny-thingy (the name escapes me right now) just turns and turns correcting the water flow slightly, but not shutting it off.The problem it that we can't find the main water valve outside the house. What am I looking for please?!? Also, we shut a valve off in the garage, but it was for the hot water.Help!
- find the house water meter located a the edge of the street in your yard and turn the main valve off
- Q: i got a filler neck for my dodge dakota and was wondering how to put it on. can anyone send me a link or help me. and also what does my EGR valve look like and i cant seem to find a new one not even at the dealer. i was told to clean it how do i do this. can someone send me a link or pic what it look like. thanks
- The VECI decal map under your hodd will show you EXACTLY where your EGR valve is. You may need a magnifying glass. The valve can be removed and cleaned with Gum-out or foaming cleaner (amsoil). When you are done, re-install the valve. While you are getting ambitious, clean your throttle body and plate, and the IDLE AIR CONTROL VALVE. A dirty IAC is the most prominant reason for the EGR valve to clog up. Running Gum-out through your intake system will clean out your O2 sensors, as well. Good luck!!
