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: I have a stainless valve I want to install in a copper domestic water line. My concern is: are the two metals compatible? Are stainless steel and galvanized steel compatible?
- How would you plan on connecting them? SS will reject solder and a welding torch will likely melt the copper. Maybe via a PVC piece as an intermediary? If the valve is threaded can you solder a threaded adapter on the copper pipe and use Teflon tape on the threads?
- Q: eventually needed mitrial valve replacement or Valvuloplasty? It is also sometimes called Acquired Valve Disease, Aortic Valve Disease or Mirtral Valve Disease. Any information would be very helpful. I was not born with this condition if that helps at all.
- There is a bloke just up the road from me had this procedure done about 3 years ago, and seems to be having a normal life. However, he is restricted on the use of strength. he was a carpenter / joiner which he has had to give up (He is in his mid 60's) Have you tried Wikipedia?
- Q: what are the factors should be know to select a control valve for specified application
- control valve is an uni-directional (non-return) valve, some of the factors to be aware of before selecting it....identify application character, select the valve size, select the valve end connection, piping layout and valve orientation , maintenance requirement , actuation requirement , initial cost ..etc..
- Q: i have been having these chest pains and i went to the doc. they did an ekg, blood test for enzymes and a echo. Well today i went back for the results of the echo and was told that i had a leaky valve but it was nothing to worry about and that there are just trace amounts of valve regurgitation. Im only 19 and i have no other history of heart problems or diseases should i be worried...they said i didn't need any anti biotics or anything and that it wouldn't kill me just to watch for it as i age into my latter years of life 50-70, but im still kinda worried..anyone else have this? im also pregnant and im concerned as to how this will affect my pregnancy, labor and delivery????
- i have the same problem,they found it when i was 40 and that's been 10 yrs ago.in 10 yrs it has put me in the hospital 4 times.but feel good most of the time.good luck.
- Q: we are researching fluid power (pneumatics and hydraulics) in my high school engineering class. Does anyone know another name for a valve? I've been able to find different types, but I can't come up with any different names for a valve. Anyone have any ideas?
- Valve comes from latin valva. There is not other name for it in engineering, but some times is referred as a cock, if the valve is used as shutoff valve, it is also known as shutoff cock. For irrigation, sometimes large gate valves are also known as gates. I can give you many names for the type of valves but I can't think of any other name that replaces valve.
- Q: I had some great answers to my question yesterday... I have decided to have the valve job done... Since I have decide to go this route... I need some reassurance, the few people I have suggessed this option to have now told me that typically after a valve job other problems will start showing up. They have said that the car isn't worth putting money into and to get ride of it.
- well, is the car in good shape otherwise, like the tranny, suspension and the body?, if it is, then its probably wort a valve job, its cheaper then another motor.
- Q: Hello, I have a 1990 BMW 525i.I would like to paint the valve cover where the BMW was written between a set of lines.I think I require a heat resitant paint for doing this.Can anyone advice the brand which will be best suited for this job.Is it advisable to chrome plate the valve cover.?with regards,natarajBahrain
- portray won't count. in case you get rid of the area to paint it incredibly is valuable to apply new gaskets! careful with the intake air hoses. they are previous an could be brittle. Even a tiny air leak will reason your vehicle to run poorly.
- Q: Do most V6's have 24 valves? What are they for? (brief description would be fine)
- Like a bath plug with a stem attached or an ice cream cornet with a straight cone, and these go up and down in the head to let petrol in and exhaust fumes out. They're driven by a cam which has lobes on it which sit on top of the valves on the end of the stem as the cam goes round and round the valves open and close at the specific time to open and close the valves. Got it now? Ask at your local library for books on internal combustion engines then all will be revealed in text and pictorially. You could also go down to your local car or motorcycle breakers and buy or look at a cylinder head, which as engineer goes is a very simple system.
- Q: give some application of varible throttle valve?
- A throttle valve allows continuous control of the rate at which some fluid moves from a region of relatively high pressure into a region of relatively low pressure. An example would be in an automobile engine, where the throttle controls the rate at which air (at or above atmospheric pressure) enters the engine's intake manifold (near vacuum when the throttle is closed.) The throttle in an automobile engine is mechanically linked to the gas pedal (in case you didn't know).
- Q: My friend is having 3 valves in her heart replaced with pig valves. Her dr said that putting in human valves raises the risk of her body rejecting them but wouldnt your body also reject a part form different species? And if they only last a few years why use them at all? shes all freaked out about the surgery so I dont want to ask her too many questions
- We recently demonstrated a third possible replacement material: fresh porcine valves . Fresh porcine valves are immunologically privileged, as they do not express -Gal, the carbohydrate antigen that is responsible for the rejection of porcine hearts. Consequently, even when wild-type porcine hearts are destroyed by primate immunoglobulin M (IgM) and membrane attack complex (MAC) deposition within 60 minutes, the valves remain structurally pristine.
