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 someone please help me on this anatomy question:Describe the physical similarities and differences in the structure of the AV valves and the semilunar valves.Thanks
- The two atrioventricular (AV) valves ensure blood flows from the atria to the ventricles, and not the other way. These are large, multicusped valves that prevent backflow from the ventricles into the atria during systole. They are anchored to the wall of the ventricle by chordae tendinae, that prevent the valve from inverting. The two semilunar (SL) valves are present in the arteries leaving the heart, and they prevent blood flowing back from the arteries into the ventricles. These are positioned on the pulmonary artery and the aorta. These valves do not have chordae tendinae, but are more similar to valves in veins.
- Q:I want to find a cheap valve that will let me take a breath in from one place then exhale through a tube going out so that i can attach an airbag to the breathing end and make a little diving lung.
- What your looking for is a check valve. Home Depot Be careful, very careful!
- Q:I've found a little beemer that's only $800. I would like to have it as a 2nd car that I'll use in case something's wrong with my main car to loan maybe once or twice weekly to my neices (16 yr. old twins). The seller says it needs a valve job. My question is, will the valve job cost me more than the car?
- almost the work is alot cause you have to practicaly take the engine apart. and its a beemer. look to spend bout 700 on the job (gaskets, labor)
- Q:I see a valve that says FNW on it with ( on, off ) but I'm not sure it's the main valve to the water supply. It does go to the water heater so I'm guessing that it's it. Does anyone know anything about the main water supply valve and how to find it?
- Find the meter, the shut off valve will be within a foot of the meter, If the meter is digital and on the outside of the house, look for a closet, or cupboard near the meter on the inside of the house, the meter will be concealed there.. The valve you are looking at is a shut off valve for the heater.
- Q:My mother is 40 and is going in on the 21st for an aeortioc valve replacement. We are so stress on deciding between what type of valve she should have to get. please help. please include things like costs and medicines and anything else that will give us more info.
- This is definitely a question for your cardiologist. I can tell you that mechanical valves will require a higher INR and they will have more problems with bleeding. A tissue valve won't last as long as mechanical, and may have to be replaced sooner.
- Q:I accidentally pushed the pressure release valve on my hot water heater last night. It ran for a while, and did not stop. I turned the water off, the valve on the cold water piper above the water heater, and it stopped running. Will this stop running at some point? The overflow tray fills too quickly for me to drain it. When I turn the water back on it starts pouring out again. HELP!!!
- the device once activated rarely reseals It is called a TP valve or temperature and pressure they cost about 15 bucks at the big box stores they usually have a pipe attached to them and are plumbed outside you will need to cut the pipe and unscrew the fitting attache to the TP Now remove and replace the TP make sure to use tape or pipe dope Do not touch the valve in the future reinstall the pipe and solder the pipe back together using a coupler
- Q:Slow songs are a major factor of this this lagging sound. Note to Note. I Oil my Valves often and they still are slow. Am I just not using enough air? Help me Experts!
- I am wondering on the make of your instrument. I have gone from a Yamaha euphonium to a Bach and now to a Yamaha pro model Baritone ,compensating 4 valve ( English bore) Having been previously a professional trumpet player I really did not like the long valve stroke on either of the euphoniums. The baritone has great valves albeit trickier on intonation.
- Q:like they say on 4 strokes you gotta go get valve jobs, and they cost bout 300 they say? well what does the mechanic do? can it be done at home and your just adjusting them?

- Q:I am replacing the Camshaft, lifters, and timing chain on a SBC 350. The motor is still in the car and I have the valve covers and manifold removed (and other components). The camshaft break-in procedure recommends removing the inner valve springs and running engine at 2000-2500 rpm for 20-30 minutes. MY QUESTION: I have the valve spring compressor tool to remove the springs. HOW do I prevent the valve from falling into the cylinder when I remove the spring? Can I conduct the break in without removing the inner valve springs?
- I have worked on many a V8 Chevy engine-350 305. I have done too many camshafts and lifters BUT i have NEVER,EVER heard that. If you remove the valve springs and attempt to run the engine, yes, your pistons will swallow up those valves.No doubt. No support, there part of the piston head. No I would say that after installing the cam lifters,etc you loosen up all the adjustable valves and let the engine start ( If It won't start and seems to chug-chug you have them too loose. So, in an orderly fashion loosen each and ever one maybe 2 clicks when the engine does start let run in this ragged fashion until ALL the valves are seated (You will know by the engine starting to get smooth) Then you tighten each one ( No order is necessary) Let the engine run for a good 25 to 30 minutes. The only problem here is the oil dripping or squirting onto the exhaust manifold.( This WILL start a fire) So, stay on top of It and flush them down every now and then. I used to, after I got the thing running in a orderly fashion, I put the valve covers back on loosely. Finger tight. Still watch It,though. But no, do NOT remove those inner valve springs.
