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 was adding air to my bike tires and the valve became loose. Do I need a new tire or is there a way to tight?
A Schrader valve coming loose is a rare occurrence. If you didn't damage anything and the valve core itself is coming loose, there's a tool to tighten them. Old-fashioned valve caps actually had this tool built in. You can still buy the tools for a couple bucks at auto parts stores. But of course, a new tube will cost about $3 and solve the problem.
Q:I gotta 89 Crx si. Just wondering if you could put on a blow off valve and it work without it boosted
Simply put...No...If you mount it on a cold air intake, you will intake air from where you mount it, and most likely throw off your MAFS and make your car run poorly
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.
The web page of the attached link has some good section drawings of the various valve types. Whereas ball and gate valves are designed as shut-off valves, and only operate efficiently fully closed or fully open, Globe valves, due to their internal design, can operate fairly efficiently in a partially open position to throttle or control the flow rate of liquids. They are used to control flow rates when mixing fluids or in batching operations where the fluid flow may need to continuously adjusted. The valves can be operated manually or automatically depending on the process.
Q:I know i have to buy a recirculating valve but should i drop 250 on the perrin or will any brand do? how important is a high quality BOV?
Go with the APS blow off valve. As for the idiot who said name doesn't matter, let him go buy a $20 BOV and have i the diaphragm start leaking at idle and cause tons of driving issues.
Q:I have a 2005 Dodge Durango and had problems with stalling. I took it into the dealer with warranty on it. They said the ECG Valve is busted and its unsafe to drive. Can you guys tell me what the function of this part is?
ECG/EKG stands for electrocardiogram. Its a way to see your heart beat pretty much. There are little waves on a screen that come up and it shows how strong or weak your heart is, and how fast or slow it beats. And what your mitral valve does is open and close to allow oxygen rich blood into your left ventrical.
Q:I got a '99 bmw 740il that is leaking and burning oil. It shoots smoke out the exhaust when i first start it from burning oil. And the car misfires when idling, i did a tune up and the spark plugs were soaked in oil causing the tune up not to help anything for long cause it was missfiring the next day. Does this sound like the valve stem seals? I bought new valve cover gaskets and grommets and im gonna replace those this weekend, im hoping that will help. Comments please

Q:wut is the purpose of this valve on tanks and on piping? explain wut the vacuum part does and wut pressure does? thanks
The pressure relief valve is to protect a tank or piping from rupturing from excess pressure. A vacuum relief valve would prevent tanks and piping from collapsing from too little internal pressure.
Q:Mitral valve prolapse have impression on lifetime?please answer with source
Mitral valve prolapse (MVP) is the most common heart defect in population. The prevalence of MVP is about 0.6–2.5%. The occurrence increases with age, and the highest is in young woman. MVP is diagnosed by transthoracic echocardiography when displacement of mitral valve leaflet(s) above the annulus into the left atrium during a systole is present (Fig. 1). The clinical symptoms of the disease are connected with instability of the autonomic nervous system. Fig. 1 Two-dimensional echocardiographic long axis parasternal view of mitral valve prolapse. MV mitral valve, LV left ventricle, LA left atrium, RV right ventricle, Ao aorta Such a large population of patients becomes a problem of social significance, and it is extremely important to determine the influence of MVP as a chronic disease on patients. That is why our trial to evaluate the health-related quality of life (HRQOL) in children with MVP was undertaken. There are many publications concerning MVP in adult patients, but no study on their quality of life has been found. The literature concerning HRQOL of children with heart defects is not very extensive; the authors analyzed the problem of patients with serious conditions, such as hypoplastic left heart syndrome, transposition of the great arteries, pulmonary atresia, tetralogy of Fallot and non-complex heart defects, like ventricular or atrial septal defect [1–3]. The aim of our study was to evaluate the quality of life of children with MVP and the impact of clinical symptoms on HRQOL. You will detailed information on the link given in sources, as it is long topic.
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!
Clean your valves properly. Use dish soap and a light plastic scrubbing pad and clean the inside the cylinder and the valve. If that doesn't work, try again using rubbing alcohol to clean the valve. Make sure that the valve guide and the little channel it fits in are clean. (use a toothpick to clean that place) You might also consider getting new springs. More air will not speed up the valves but it will help you maintain a constant sound.
Q:A question about a hot water radiator bleed valve. I read the advise on previous questions and bleed all my radiators except one where the bleed valve broke off when I tried to turn it with the key. My question is that on the other side of the radiator near the floor there is a black knob that turns which I assume should shut off the radiator. If my assumption is correct then I should be able to shut this off and then remove the bleeding valve and replace it without bleeding the system.. Does this sound right? Thanks,.JOE B
make sure both sides of the rad is off if there is only one shut off you have the pressure dropped from the system and youll have back pressure from the system.. call a gasfitter..
