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

♦ 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: hi My Dad is 65 yrs old. he is very fit and healthy. He has had heart problems as long as i remmember! he has been under care for almost 2 years now and he has had to stents put in. Now the doctor has found out that his Mitral valve is leaking. They have told him tat he needs surgery to either have the valve replaced or repaired. i like to know if anyone out there has been through this and can help ease this a little as Ia really worried!! Thank you!
- Mitral valve surgery is surgery to either repair or replace the mitral valve in your heart. Minimally invasive mitral valve surgery is done through much smaller incisions (cuts). In open surgery, the surgeon makes a large incision (cut) in your breastbone to reach the heart. Mechanical heart valves do not fail often. However, blood clots develop on them. If a blood clot forms, you may have a stroke. Bleeding can occur, but this is rare. Biological valves tend to fail over time. But they have a lower risk of blood clots.
- Q: Pressure relief valve on boiler is dripping.Starts to drip more when the boiler is turned on.Bad relief valve?
- Only to add what Steve said, make sure you have a pipe leading from the Safety valve to the floor, that way if the Safety valve let's go it won't be shooting straight at someone's face or other equipment. If you could, pipe the safety to a drain but by all means leave the line open, Put no other valve in the line to restrict what the safety is meant to do.
- Q: When i disconnected my Diverter Valve and made it non-recirculating i drove down the street and my engine cut out on me. it will go a few feet and after the excess pressure is released (PSHH) the car cuts out. i reconnected the valve tubing making it rec-circulating and it works fine. im baffled i know VW is supposed to run a DV but last night i saw a stock VW GOLF running blow off and he was stock. any ideas? it is an after market DV made by forge.
- Yea... The 1.8T is made so you have to recirc your dv. You can run a BLOW OFF valve off of your throttle hose, but thats a lot of redirecting and work for some silly extra noise. Chip that Passat to get some more turbyturbo noise. Y was there a stock golf with a dv? I'm confused...
- Q: Can anyone recommend valve manufacturers who make a good electric high temperature valve. The temperature that I am looking at is 1600 F at 100 psi. It should be electric magnetism controled. Is there anybody know what is the highest temperature the valve can bear in the world?
- google 'inconnel valve' look for foundry equipment suppliers Can you valve the gas away from whatever is hot, or is your gas at 1600 F and 100 PSI ? If so, what are you using for piping ?
- Q: where is the fuel tank selector valve located on the truck?
- Located under the LH center of vehicle, on LH frame rail
- Q: Is it safe to remove the butterfly valve on my 94 celica 1.8l st?
- Why would you want to do that? The butterfly valve is a very important part of your engine. It is what gives your foot the ability to control engine RPM's. Therefor don't be stupid and mess with something that you will possiblly regret later
- Q: Sohc ZC (d15) honda I'm going to be painting my valve cover am I going to need new seals? What do I need to take it off and put it back on ? Please help I have the high temp sand paper all ready to go I just want to be ready
- if i were you i would replace the gasket ! even if it don,t break taking it off it,s best to put a new gasket on when you pull the valve pan !
- Q: Hi, in the heart, blood flows through the AV valves and enters the ventricles once the atria have filled up with blood. What opens the AV valves? Fluid pressure from the blood or the SA node pulses?
- The opening and closing of the atrioventricular valves is controlled by the differences in pressure across them: When blood passes from an atrium to a ventricle, the atrioventricular valve is pushed open (and the papillary muscles relax and the chordae tendineae lose their tension, becoming slack). At the next stage in the sequence the ventricle contracts. This forces blood out from the ventricle into the artery via which it leaves the heart. This contraction of the ventricle and the corresponding increase in blood pressure within that ventricle also presses the cusps of the atrioventricular valve together until their edges meet, closing the valve. At the same time, the papillary muscles contract and the chordae tendineae tighten - both of which also help to prevent the cusps from enabling the atrioventricular valves to open. When in the next stage of the sequence the ventricle relaxes and the atrium contracts, the blood pressure situation is reversed, the relaxation/tension of the papillary muscles and the chordae tendineae also reverses, and the atrioventricular valve allows blood to pass from the atrium to the ventricle again.
- Q: what is the purpose of valves such as: gate valve, foot valve and globe valve in the industry?
- Valves are used to stop/start or control the flow of liquids or gases in pipes. There are many many kinds of valves, so if you want info on a specific type, just list that.
- Q: Hi, this is a part 2 question to the one I posted last night. After turning the water shut off valve on my toilet back on, it didnt start to hammer till about 1 min pasted. When the hammering is happening I look in the toilet tank and see air bubbles coming out of the base of the fill valve and the water coming out of the fill tube isn't smooth and flowing its kinda step wise/ in intervals. I forgot to mention that I live in an apartment, does this affect anything?My official question is, is this an air bubble problem or is it a rubber gasket/ rubber seat problem?This is a new building only about 2 yrs old, so parts can't be that bad right?
- First check for a kinked or twisted supply connector hose. You may also have a piece of rubber gasket/washer debris stuck in the valve body (seat washer) or in the fill valve itself (from the connector compression washer). Shut off the water supply at the angle stop and disconnect the supply hose from the fill valve nipple under the toilet tank. Get a bucket and put the end of the supply connector hose/tube into the bucket and open the supply valve again. If it still hammers when unrestricted like this, the obstruction is in the anglestop valve body. The water pressure may force it out, but if it doesn't, you'll have to shut off your main water supply to clean the stop or replace it. If it doesn't hammer when unrestricted, the problem is now in the new fill valve, and is probably a deteriorated piece of the compression washer in your old supply connector hose or tube that has been pushed into the fill valve. Since it's a Fluidmaster, you can disassemble the head of the valve and remove any visible obstruction or just replace the top part.
