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:Can anyone tell me what is the industrial application for globe valve?? Please help. I tried to search in the Net but couldn't get.
- I will rstrict myself to only the types other wise the selection criteria are many. GLOBE: These are used for controlling a process parameter loop. They cause medium pr. drop are ideal for clean fluids. The shape of the stem is contoured to get the desired characteristics. The repeatability of the type in flow control make it ideal for closed loop control. BUTTERFLY: These are low pr drop devise that are used primarily where u can't allow higher pressure drops. Good for clean fluids in on/off service. Even allowed for gases. it opens/shuts faster than other types of valves. Sealing characteristics are not as good as ball valve, particularly unsuitable for fluids containing solids.
- Q:i'm being charged $300 to replace a 75gallon water heater valve, is that too much?
- on the high side 60 bux other than that you can get half a new heater for 300$ crazyness/
- Q:Hi, I was told by my gardener that I need new sprinkler valves and each of those run about $50-70. I looked up online and I found them for $20 or less. Also what is the basic labor cost for getting them installed? I got estimates that range from $300-1000. I am confused.
- they screw in and out, acouple of wrenches, a shovel, a roll of teflon tape, all less than 300$
- Q:In December I got a new John Packers Bb Cornet and it was fine to start with. But recently the valves have been sticking, especially the 1st and 2nd ones. Even when I put valve oil on them they stick. It's really starting to annoy me, is there any else I can do to prevent this?
- If the valves continue to stick after being oiled, then it's time to clean your horn. Remove all the valves (making sure to keep them in order so you don't put them back in the wrong casings) as well as the slides. Fill a sink with warm (not hot) water with liquid dish soap. Wash all the parts gently with a soft clean cloth. There are special brushes available at music stores for cleaning the insides of slides. After cleaning, pat everything dry, apply fresh grease and oil, and reassemble.
- Q:i dont get how valves produce the sound? and why did we change to solid state? was that because they we're used in stereos?
- Most valve amps I have used reproduce the sound of a tube amp. Tubes have a warm sound and can be overdriven to get that good rock crunch distortion sound. We went to solid state because they were durable and didn't require the maintenance of a tube amp. Printed circuits and transistors cut the cost of manufacturing. The old tube amps still have the purpose and they never quite matched the exact sound of tubes with the solid state amps. That is why they are making a lot of tube amps now.
- Q:We have a 2008 grizzly 700...Lately when we run the 4-wheeler there is a ticking like noise (as is something were loose). I have been told by a few people that it sounds like the valves need adjusting. Does that sound like what it is? Will it cause any damage to the 4-wheeler if we ride it before we get a chance to adjust the valves?
- They are correct. Well almost. The Rockers are what can be adjusted. They are too far away from the valve and are starting to hammer on them instead of just moving them. You will not cause immediate damage by riding it but you could wear out the rocker completely and drop a valve into the engine which would be very costly. Best to get it repaired soon. Make sure they install new rockers and springs. The main cause for this is poor oil maintenance or poor grade of oil being used. Always use a GOOD synthetic oil and your motor will last 10 times as long
- Q:I saw some other answers. I figure the relief valve needs replacing, ok no problem, but exactly how much pressure are we talking about here? what is the correct procedure to shut this thing down to replace the valve?
- Same thing happened to me, but with an oil boiler. Shut off power to water heater. Find the drain valve on bottom of unit, attach hose if it has a fitting. If you have an open sump pump in you basement, just drain into there, or you can fill buckets and keep emptying them. Use a pipe wrench to take of pressure relief valve. Take the valve to a good hardware store, or plumbing supply place so they can match it. Put teflon tape on threads of new valve (thats all i used, no leaks) and install then refill tank, you may have to manually hold down the water feed line. turn on power, and open all faucets to bleed out the air.
- Q:I am 31 and just discovered I have severe Mitral Valve Prolapse (Heart probelm). I probably have to have surgery. I have been healthy all my life and I am a little scared. Anyone had surgery for it? What can I expect??
- yes. In Feb of last year. Had a gradually worsening valve and regurg. Had it done at UVA teaching hospital by an excellent surgeon and 2 doctors who were months away from being certified themselves. IN at 6 am, spent most of the day in surgery, stopped my heart, cut open my breastbone, opened my heart, sewed in a ring and trimmed the valve, closed and restarted. Spent a week in hospital; three weeks at home recovering and was released to come back to work at a very low physical demand (and driving a car with no airbags). Couldn't lift or pull anything for a good six months being cautious mostly about the wires holding my breastbone together. Was on blood thinner for about 45 days and on severe pain meds for about 30. HAd a little fluid develop on a lung that eventually cleared, and some anemia issues that also creared up. After 6 month, my cardio told me it went well enough I didn't have to see him again. Year later, only real side effect is some residual fatigue (im 51) and my breastbone gets sore when I'm tired or overstressed. I'm not a smoker and they said this was textbook. No worries man; you'll blow thru it
- Q:Ok. I have to ask cause I have been in hospital all weekend after having a moment on saturday when my heart decided to start racing. Woke up 4.30am on saturday morning cause of blood test which kinda showed I could have had a heart attack which was scarey and though I was discharged today I got told I had a leaking aortic valve. What does this mean and what is going to happen. I am honestly really worried cause it cant be good
- The valves of your heart valve are not closing properly. Very common thing. May or may not require surgery. May or may not be related to you having a fast heart beat. Ask your dr to tell you what the racing heart was about. They would have a record if it was significant. Or your doctor may want you to wear a monitor for 1-2 days to help to catch this so it can be identified.
- Q:Can anyone tell me what to do if i know that I have the type of valve stem that was recalled TR413chrome?? Will they replace them for free since they are a recall or do I have to dish out some more $$ to fix the problem??? The company that sold them to me is in Florida (Wheelmax) and I am in Mass. Not sure what to do to avoid having to pay out more $$ to have them replaced...any help is greatly appreciated
- well really they should dont see the big deal they are like a buck each... and will take ten minutes to fix.. at any shop some places might cost you 10 to 20 bucks.. and yes if there is a recall on valve stems im sure they would redo them for free... . ive never heard of one been doing tires over 20 yrs.... rubbber gets old and dry about as fast as the tires wear out
