Product Description:

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

♦ 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


♦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:700r4 throttle valve......?
700r4 Throttle Valve
Q:Can anyone explain me the basic differences between a gate valve and a globe valve?
Well, we're all around it. I like the answer the gate valve is like a garage door. That is about right. A globe valve the flow through the valve is forced through two 90 degree turns and the valve shuts off like a lid coming down in between the two turns. Not sure why the fire requirements are that way.
Q:Is mitral valve anything to worry about it?
i wouldn't worry too much at the moment your cardiologist and you dr will keep a close eye on it Medication can't correct a deformity of a mitral valve. such as diuretics are available to relieve fluid accumulation in your lungs or legs, which can accompany mitral valve regurgitation. High blood pressure makes mitral valve regurgitation worse, so if you have high blood pressure, your doctor may prescribe medication to help lower it. Following a low-salt diet helps prevent fluid buildup and helps control blood pressure looking going back yrs ago they used to replase them srtaight away but the diffrent tenics now they dont do it straght away but try to sort it with medication it can be repaired if the heart is not pumping very well but this is how a repair is done if your heart is not too bad Your mitral valve consists of two triangular-shaped flaps of tissue called leaflets. The leaflets of the mitral valve connect to the heart muscle through a ring called the annulus. The surgeon can modify the original valve (valvuloplasty) to eliminate backward blood flow. Surgeons can also repair the valve by reconnecting valve leaflets or by removing excess valve tissue so that the leaflets can close tightly. Sometimes repairing the valve includes tightening or replacing the ring around the valve (annulus). This is called an annuloplasty. It's important to have an experienced surgeon perform mitral valve repair i hope you find this an help to you but as i said you dont have to worry too much yet you have a good chance with your tests you can lead a pretty good life and if need be they would do more if it came to the worst hope this as helped you
Q:pulmonary valve stenosis in my eight month old daughter.?
I don't know if it's the same but my son had aortic stenosis when he was born. After many tests it just went away and no they did not have to do a catherization. Never caused him any problems either.
Q:89 Dodge Ramcharger Valve Cover?
Virtually speaking yes, the engine size or displacement is the same on all 318 engines. You can obtain a newer valve cover which will fit your 89.
Q:Would a ERG valve cause sputtering or hesitating on my pontiac firebird?
If the EGR valve is opening on Acceleration yes this would cause hesitation,but you have to find out why it is opening if it is.If there is a solenoid controlling the EGR valve this might be the problem.If you can put your finger under the EGR valve when the engine is idling,rev then engine up in park,if you feel the valve opening it is most likly the solenoid
Q:1979 oldsmobile pcv valve?
look on the valve covers.it will be at one end with a hose running to the carb.
Q:1997 Chevrolet Tahoe Air Conditioning Pressure Valve?
You will have to evacuate the A/C system of it's freon to replace that schraeder valve.There is a tool that is similar to the one used on valve stems on tires that you might get and just try to tighten it first. That tool can be found at automotive A/C supply stores. Don't try to use anything else or you might mess it beyond repair. If you replace the hose you will also have to evacuate the system. I would try tightening it first. Also I've seen people just put a good o-ring under the cap that goes on it and tighten the cap real tight to avoid having to evacuate the system.
Q:whats a leaking aortic valve?
It just means that one of the valves in your heart doesn't completely close. So when your heart pumps blood it doesn't do it as effectively. I have a leaky mitral valve and I have no symptoms. I just have to take antibiotics anytime I have dental work done. Bacteria from your mouth like to mess up your valves if they are already leaky. But it almost never happens. It's just a precaution. You really need to talk to your doctor about what he found. He needs to explain whether it's serious or nothing to be worried about.
Q:mitral valve regurgitation and surgery?
The valve should be replaced under two conditions: it is causing symptoms that interfere with your lifestyle, or it creates a risk of more serious medical complications. It looks like it isn't affecting your lifestyle. It would be a good idea to ask your doc about the possible complications that might arise from your particular situation and also find out the likelihood that those complication might arise.
