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:What are these valves on top of my compressor?
The valves are probably one way check valves and the line is called the discharge line. The valves could also be un-loader valves that release the head pressure when the compressor shuts off. For parts just google your compressor brand and model for parts dealers.
Q:Pinch Valve?
a pinch valve has a membrane (or sleeve) inside the valve. When the valve handle is screwed down the membrane is pinch closed. This type of valve is good when the flow needs to be finely controlled. It is also good for slurry (abrasive) flows, as the membrane can be replaced when worn. Gate valves are less effective when the flow must be controlled. They are not used in slurry applications at all, as the gate will be quickly worn away. Knife gate valves can be used in slurry, but are generally totally open or totally closed. The valve must be installed the correct way around, as when closed the weight of the product against the knifegate helps seal the valve. If you have the wrong way around it will tend to leak.
Q:Dr says I have a leaking heart valve but not which valve.?
i exchange into an open coronary heart RN. we frequently operated on people for the 2nd time, often desiring valve replacements. an consumer-friendly hassle after a 2nd time around open coronary heart surgical treatment is bleeding. the 1st 12 hours is extreme. countless those victims pull by using and do only extreme high quality. stable fulfillment with your Dad.
Q:96 toyota camry expanssion valve location?
the expansion valve is usually located inside the line next to the accumulator/dryer. If you drain the system, and remove the accumulator, look inside the line that leads into it, and it should be stuffed in the line. If you see one inside the line, it is actually called an orifice tube, but has the same function as an expansion valve. Actually, expansion valves are usually used in large vans with a rear a/c evaporator unit. If it is an external valve it should be next to the accumulator as well. The purpose of this valve/tube is to create high pressure gas out of low pressure liquid freon. These usually become clogged with debris after the compressor's pistons break apart and contaminate the system. If you find little metal shavings in the tube, or valve, your compressor was either replaced at one time, or is bad now.
Q:Cold air intake - bypass valve or not?
Only version 1 of the AEM CAI's could even use the bypass valve. Version 2 will not work with this bypass. This bypass valve is pressure sensitive and set up to open if the air flow was blocked at the filter. It also has a foam filter on it to still give you some filtration of the air. You do not want to drill a hole in the intake. This will allow unfiltered air to enter your intake and reduce the efficiency of the intake system. I'm not sure what kind of car you have this system on, but on my Accord, the filter was moved down inside the front bumper just in front of the drivers tire. It is surrounded by plastic and has minimal chance of any water splashing in to it. The only way I can see water getting to it is if I were to try and drive in to a large Pool of water in which it would have to be higher than the floor of the car. Anyone who would even attempt such a thing would be a fool in the first place for trying to run through such high water. If you have the Version 1 AEM, get the bypass valve. Don't drill holes. If you have the Version 2 which can not use this valve, just don't try to use your car as a boat. You shouldn't have any problems. TGP
Q:Using thicker oil to eliminate valve clatter?
I wouldn't go any thicker than 10w-40. I have seen 20w-50 in the parts stores, but this will put a lot of strain on the oil pump. You may regret it down the road, and it's just a little bit of noise. Good luck.
Q:Severe aortic bicuspid valve?
There are minimally invasive approaches, and there are many different techniques of valve surgery and all valve replacements, with choices to provide each patient with the best possible treatment.The patient will normally choose, with their surgeon, the type of incision, the type of valve and the technique. Valve repair versus valve replacement, with coronary artery bypass if necessary. The choices will normally depend on the patient’s opinion, their health history, and their surgeon's opinion. After successful aortic valve replacement, patients can expect to return to their preoperative condition or better. Anticoagulation (blood thinners) with a drug like Coumadin may be prescribed for 6 weeks to 3 months after surgery for those with biological valves, and for life for those with mechanical valves. Once the wounds have healed, most patients should experience few if any restrictions to activity. A patient will require preventative or prophylactic antibiotics whenever having dental work, and should always tell a doctor about their valve surgery before any surgical procedure. Hope this helps Matador 89
Q:transmission valve body?
one thing i have done on some cars with shifting problems is to flush the trans fluid. bring it to a good shop and have them FLUSH it , not just change it. you can do it yourself without any special equipment but you will have to drain and refill the system about 3 to 4 times driving it a few miles inbetween to circulate the oil - it is a real pain in the ***
Q:How to seat the float valve on my 10 hp Tecumseh carburetor?
A disfunctional float valve will cause the carburetor to flood from fuel spilling over the top of the float bowl. The float valve acts like a toilet valve and just fills the float bowl up to the top and closes until the level drops from the fuel evaporation being pulled off while running. I don't know the exact specs, but you should be able to guesstimate and adjust by bending the float tang, or just replace the float valve.
Q:Cleaning trumpet valves?
Remove the valves, wash them and the horn in warm (NOT hot) water with liquid dish soap. Dry with a clean towel, then oil and reassemble.
