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:When you regulate flow with a valve in a fluid circuit, obviously the flow changes. But mathematically, it changes in function to what? the minimum cross-sectional area? I mean it has to have something to do with some integral of sth (since a valve can change the cross-sectional area of a portion of the tube with length of almost zero and the flow would still change dramatically). I have no idea how to work this through. Can you tell me what changes when you close a valve, which makes the total flow change?Please answer asprecisely as possible, this is for a college essay! thanks in advance!
- A valve reduces the cross-section of the pipe. .
- 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.

- Q:How would you change the Heater control valve on a 1997 honda civic hx?its my first car, so i dont know much about cars.
- confident get the screw clamps. those spring clamps you would be able to besides throw them over the hill by way of fact while they're used then they get susceptible. plus with the screw clamps you may continually tighten them in the event that they must be.
- Q:P.S.V. Pressure Safety Valve
- They okorder or other relief valve sites for more information.
- Q:When I went to cardiologist he said i had normal EKG, excellent blood work high HDl 58, low triglycerides only 51, and LDL was like 71, ejection fraction of 65% he said I was fine but he said I had mild mitral valve prolapse. DO I have to worry abt the mitral valve prolapse? Im healthy and can I live a normal long life any opinions?I dont smoke, dont do drugs, no family history of Heart problems just some cholesterol but mine is low so Im good
- In 95 plus percent of cases so-called mitral valve prolapse is a normal variant. If yours was other than a normal variant your cardiologist should have discussed this with you. As such I would not worry. JR
- Q:Where is the mixer valve on a '94 Dodge Caravan with a 3.0 V6 engine?
- which valve are you talking about,fuel injection is mixed automatically with the air and fuel ratio through the injectors,i hope that was what your talking about,good luck.,,PS i don't think a 94 model uses a mixing valve,if it does have one on it it will be before it goes in to the firewall in plain site.
- Q:Also what prevents this from occuring? I have a lab due tomorrow for my biology class this is one of the questions. the answer is no where in my book, and we haven't discussed this in class. im also having a hard time finding the answer online. i would assume it would have something to do with the elasticity of the valves, and i know that when valves are weak sometimes blood can flow back into the artium when the ventricle contracts causing a heart murmur and other problems, but i haven't came across any information that talks about the valve being pushed backwards. if you can help me out that would be awesome! thanks =]
- Valves, because they open when your heart pumps and close, not allowing blood to flow backwards after the pump.
- Q:Since the valve drain is usually open, I am wondering if placing the cap on the drain has made my water heater dangerous.
- If it is the drain valve and not the pressure relief valve, you should be fine. The drain valve is not usually open, just when the sediment is drained out of the heater or when it is drained.
- Q:I have a intake valve leakage in both my car and truck. If there some sort of quick fix i could use to stop the leakage for about 1 month.
- IF the valves are correctly adjusted, then the only solution is a valve job. Certain vehicle engines are more prone to burning valves than others.
