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 would like to hear from anyone who has actually had the work done. i also would like to know if the valve worked.
- I have never heard of a backwater valve. What kind of car is this? We need Year, Make and Model Can you be more specific.

- Q: Hi. I looked at instructional videos for installing shutoff valves and instead of simply unscrewing old valve, the plumber simply cut the copper pipe. Is this necessary? Why can't I simply unscrew old shutoff valves from copper pipe?
- Shutoff valves come in two varieties. 1. A compression fitting and looks like it is bolted onto the pipe. 2. Is soldered onto the copper pipe at each end of the tap. If you are paying your plumber by the hour, believe me, you will want him in and out including travel time in under an hour. If cutting the copper is and would be his quickest way then let him have at it. Good Luck Richard
- Q: When and why do you need to get a valve job? My car has 85k miles on it. What is the difference between a valve-job and valve-adjustment? what would the increase in power be on mine? 3800 series 2 engine, assuming it is just a little old, no major problems. 5-10hp?
- MOST modern engines have hydraulic lifters, which pretty much eliminates the need to have any periodic valve adjustments. You can take stock heads to a shop and put two grand into them and make better flow and bigger valves and more power, or actually buy a set of performance heads for less and make more power. the only time your valves would need to be set is when putting together a new engine, or taking apart the one you have and replacing say a head gasket or something. (in which case you would have a shop go through the heads and make sure they are up to factory specs. If your engine is running fine, and you have kept the oil clean and the motor in good tune, follow the recommended maintenance intervals in your owners manual. a valve adjustment is not going to give you horsepower.
- Q: How much will it cost to fix 5 broken gas valves out of 6 from my truck it's a Chevy s10 99'I live in North Carolina
- ...Gas Valves???....WTF....
- Q: I gotta 89 Crx si. Just wondering if you could put on a blow off valve and it work without it boosted
- A okorder /... but this is like putting playing cards on bicyles!
- Q: I am doing a big project on Valve and it's games. I am currently doing some research on the company and wanted to see if anyone had any interesting facts or information about Valve that may be useful when doing research, thank you. :)
- i just watched it again.. haven't seen it since it was released. Since then they've made Team Fortress 2 free to play, and any gamer that plays f2p will tell ya.. f2p/microtransactions are the future. Also they came out with Alien Swarm, and amazing isometric shooter where you had to rely on your teammates much like left for dead.. but even more indepth group dynamic. Then Portal 2 of course.. and DotA 2 is still in beta but looking great also. I really think the 1 thing that makes Valve so loved is the relationship it has with its consumer/gamers. Especially in the modding community. I know alot of people like me who will stand behind Valve in all their future games.. and that's perty damn crazy to say for a company that is trying to sell you things... especially in the Video Game world where so many are out to squeeze every dollar out of their customers and IPs.
- Q: Hi, I am a junior in high school and I play the trumpet. For the past week or so my 1st valve has been odd. It gets stuck badly when it hits all the way to the bottom, and I can't seem to get it to stop. Normally when valves are sticky I just use some valve oil and it helps a lot. But it doesn't seem to work this time. It is a Bach if that helps. I think there are other types of valves so I'll say that there is a spring inside from like the middle to top. If you could help me out that would be great! Thanks =)
- Instead of valve oil, try kerosine. This is no joke. I found that kerosine cleans the **** out of the valves, and makes for smoother valve action. Put about a 1/2 pint in to a a peanut butter jar, and you can let the valves soak a for a few seconds before you put them back in. i got this tip from a trumpet player who played professionally in a dance band.
- Q: I want to put a blow off valve in my car to make it sound cool lol but i dont have a turbo yet ... do i even need one?
- yes, you need one if you don't have a wastegate
- Q: Does the heater control valve anything to do with the A/C ?My heater control valve needs replacing, as it leaks when I put my truck's heat on. No heat, no leak. I have to periodically re-add Prestone every once in awhile after using the heat . I've checked the valve and it only leaks when I have my heat on, if I don't use my heat, I don't lose fluid. But now I'm wondering if I use my truck's A/C, does the heater control valve have anything to do with the radiator fluid, or just the freon? Thanks in advanceCar Mechanic in training
- What you may really want to check is if the heater core is leaking. I have never heard of a valve actually leaking. And no the AC and Heater are 2 different systems on a car. The fan that circulates the air is the same except air flows across the heater core or the air conditioning coil. AC air is usually just recirculated in the car air where heated air is usually outdoor air combined with in the car air.
