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:where is the oil pressure relief valve at in a 2003 ford focus
- its in oil pump some engines have a oil filter relief valve in behind the oil filter that can cause this problem but not certain if your engine does but worth a check
- Q:Hi My sons car has alloy wheels, and metal valve stems, there is a tiny leak between the valve stam and the alloy on one wheel, we are struggling to get anyone to repair at a reasonable cost. Would tyre weld make a permanent repair?. Some tyre specialists won't touch the wheel, one other wants to drill out the stem put in another, which sounds a bit drastic. Any other ideas?, is it feasible to get the metal valve stem replaced by a rubber version?. Apparently the metal ones get curbed and then start to leak.
- On that year car the tire is tubeless and the valve stem should not be moving as it would if you had a tube type tire. If the valve stem is pushing in it means you drove on the tire while flat and probably ruined the tire as well as the valve stem. The tire must come off the rim to be inspected before blowing it back up and used. If you don't inspect the tire it will probably blow out at highway speeds and kill someone!
- Q:I just bought my first bike in 20 years, and as a result have had to pump up a bike tire for the first time in 20 years. I was dazzled to discover a type of tire valve that I'd never known about. The Presta.So of course, I need a pump with a special adapter, I didn't know to unscrew that nut at first so I accomplished a whole lot of nothing for awhile, and once I did open the nut, the pump kept slipping off the tire once I got anywhere near the tire' recomended PSI until I awkwardly held it in place while operating my pump with one hand, which of course meant less leverage and so while I got above the min recommended PSI, I couldn't get anywhere near the upper end of the spectrum. Why would anyone use these ridiculous contraptions? The fact that they are used means there must be some rationale. A brief internet search seems to find more forum posts with people saying the alternative (Schraeder) valves are more reliable and don't leak as much either.Educate me!

- Q:non-return valves
- ..?..non-return valves..? I will assume that your 'non-return valves', are what is also known as check valves. Check valves allows flow in one direction only. These are used wherever you need to prevent backflow into the system, or to maintain a charged circuit with fluid, until you choose to unload(depressurize ) it. Now, why are they used in discharged lines of salt water, basically to prevent backflow....reason not known, here , requires usage info.
- Q:freak accident broke the shutoff valve at my toilet, so first thing i did was shut the water off at the main shut off valve inside the house. then fixed the toilet shut off valve then went to turn the water back on at the house valve and it ran for a few seconds and that was it. so i then went to the main valve at the street to make sure it was open. it was open as well as all the others inside the house. still no running water. please help.
- did you strip the knob handle?
- Q:P.S.V. Pressure Safety Valve
- psv is a pressure sensitive valve the other is sspring loaded and will fail in time
- Q:im looking at buying a 1995 ford probe, but it has a busted valve in the head, does anyone know how much it would cost to have fixed?
- stay away from it
- Q:Im living in an a house previously own but abandonded , and im trying to get water, the thing is the pipe where the shut off valve is is dettached , and i dont know where to reattach it nor do i see the missing pipes to reassemble what does the main shut off valve attach to in my house?
- the water line is probably a copper 2 line coming into the house...where it meets the water meter and on the other side of the meter is a shut off valve then it goes into the house. perhaps the water is shut off at the street
- 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:How can I tell if my 2004 Ford Taurus a 12 or 24 valve?
- You can try and look up the VIN online or call the Ford dealer and ask.
