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
Peformance:
♦ Type: Conventional, Bellows
♦ Size:1" D 2"- 8" T 10"
♦ Class:150lb~2500lb
♦ Temperature:-268~+538°C
♦ Fluid: Gas, Steam, and Liquid
♦ Material: Carbon steel, Stainless steel, Alloy steel
♦ The allowable tolerance of the set pressure: ≤±3%
♦ Overpressure: ≤10%(gas)/≤20%(liquid)
♦ Blowdown: ≤10%(gas)/≤20%(liquid)
♦ 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: Hi. I am planning to install new kitchen faucet and noticed that there are two shut off valves under the sink. One of them is badly rusted and needs to be replaced. I noticed that it is connected to three pipes (one of which is kitchen faucet). The other is clearly water coming in. What is the third one connected to wall? Also how should I go about replacing this? Anything that I should be careful of?
- make a drawing of what you have. . .take it to Home Depot or better yet, a plumbing suppy place. They will be able to replace what you have. Just replace what you have and it will work. The interesting thing about shutoff valves is that they are always broken when you need them and work when you don't. They last no longer than what you are protecting. Buy the best ones they have. I have a strange one that is connected to three pipes. . .the water comes in one and goes out to the faucet and the dishwasher. . .three pipes. That's the hot water. And then the cold water comes in and goes up to the faucet. .the second shutoff.
- Q: I know what a blow off valve is but where does it blow out the air out off does the air blow out threw the exhaust or what?
- Depends on the type of blow off valve. Some vent to atmosphere(just blow it out into open air) others recirculate(blow the air back into the intake farther upstream). Which one it does depends mainly on where the blow off valve is located in the system. If the car has a MAF(mass air flow) sensor and the blow off valve is located after that sensor then it has to be recirculated, because the sensor has already registered that air and if it vents to atmosphere then the engine will run rich because the ECM will be putting too much fuel into the engine.
- Q: I am buying a 2004 Ford Taurus tomorrow and want to know the difference between a 24 valve V-6, and 12 valve V-6...Now besides the obvious difference in the # of valves...Is one better then the other???
- The 24 valve has 2 intake and 2 exhaust valves when the 12 valve only has 1 intake and exhaust per cylinder, the 24 would give u more power but will most likely use more gas.
- Q: It's just a small 1 cylinder 1000 watt generator but thanks to contributors here, I verified the exhaust valve is pitted after I cleaned it all up with oven cleaner a toothbrush. My question is can I just replace the valve itself or do I need an entire new head? The seats still feel smooth.
- You can replace just the valve. You should lap the valve to the seat though. That requires a lapping compound and some way to spin the valve. This is done before installing the spring. Lapping ensures that the valve is seated and won't leak. In the old days I have used comet cleanser and a small suction cup chucked in my drill. Worked fine. I know that is not the correct method but it worked and my mower ran for several years after that. Auto zone may have a valve lapping tool that they will loan out and you can buy some real lapping compound to do a better job. I always enjoyed getting the job done with what I had on hand. Good luck.
- Q: I have a 2000 Mitsubishi Eclipse GT.I just replaced the EGR Valve yesterday, and disconnected the battery to reset the code.My old valve was nasty and loaded with carbon and the valve wasnt even opening.As soon as I drove it out of my driveway with the new valve I IMMEDIATELY noticed the difference, as it was back to normal and felt like the car moved quick again without the knocking. But after about 20 miles, the light came back on [the car is still running perfect].Today I went to Autozone and had it scanned, and sure enough, code P0403 came up as EGR Valve Circuit. He cleared the code out, and I drove to a nearby store, and when I came back out and turned my car on, the code was back AGAIN.What's the problem?If you have an idea of something else that I should check, please give me an idea of where it is located.Thank you.
- if your valve was carboned up then you Dp sensor is probably clogged as well and that would cause the light to come on and it would give that code. You can more than likely take it off and clean it really well with something like LPS or brake cleaner...carb cleaner would work also
- Q: im just bored so heres my question who do you think is better valve games (hl2 tf2 css) or bungie games (halo) and why. whoever gives me the best reson gets best answer. personally i like valve
- While Halo is great, Valve wins out here because of the variety of games it offers, such as the Half-Life series, Portal, and Counter-Strike!
- Q: any flash files explaining valve operation maintenance will be very much helpful
- A pressure relief valve or safety valve is used in pipe lines or any other pressure vessel (pressure cooker for eg) where pressure exeeding the strength of the metal of the container or the pipe has to b avoided to prevent failure of the metal or possible explosion.in a pressure relief valve the inlet of the valve is connected to the pressure area where as the outlet is connected to atmosphere.the valve lid is held against the pressure via a compression spring.when the pressure in the pipeline or pressure vessel exceeds the spring pressure the valve lid opens and the pressure is relieved.
- Q: Kenmore washer ,cold water trickles in, pressure from faucet OK. Must entire valve be replaced?
- see if you can find a manuel on it also try tracing the wires that go to the valve and back track from there. there is also water level switches and tempture switches that might be messed up
- Q: I need to find a solenoid valve with the following specifications:2-way, 1 inch nozzles (both male)needs to be able to handle the pressure from a CO2 tank (~1000 psi)needs to work with 12vdc less than 10 ampsits either a solenoid, or some other type of valve which will release the CO2 when we tell it to electronically
- The leading maker of solenoid valves is ASCO. Their website is shown below. If a valve that fits your application exists they probably make one. If you can't find a suitable solenoid then you need to consider a pneumatic valve operated by a solenoid valve. That is a common solution for a problem like yours. As to the male connections. If they are not available then you can just use a pair of threaded fittings (pipe nipples) to change the configuration.
- Q: The water shut off valve that is under my sink in the bathroom is leaking and I need to replace it. I am wondering if I need soder the new one or can I just put some thread tape around it.
- TURN THE STOPCOCK OFF OUTSIDE ..DRAIN WATER OUT OF THE TAP AND REPLACE WITH NEW ..
