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

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: the blow off valve has a hose that goes to the intake. Do you need that hose.
- if you want it to operate properly the yes you will need it. The valves are also adustable but you need a tech manual to and special tool to do it propperly dont just guess at its setting rather know it. I assume the picture i looked at was your engine. Unless you like taking chaces i would recomend you put your timing belt cover back in place. If anything should get in there between your t-belt and gears or pullys the belt could be damaged and if it does get damaged you could damage the valves in the event of t-belt failure. I know people like to see the belt and gears moving and if that is what you are wanting i would suggest installing one of the clear t-belt covers that are available. unfortunatly i do not know who makes them. if you cant find out go to a car show and talk to gear heads that have them on there cars.
- Q: Ok so i am 16 years old, and i have Aortic stenosis, bicuspid aortic valve, aortic regurgitation and an Enlarged aorta. I am soon going to be getting an aortic valve replacement. I am just wondering what happens before and after the surgery and how long i will be in the hospital, how long in the ICU, what kind of tubes/machines will i need? any information will help. thanks :)
- They will probably do a tissue valve replacement so there would be no need for life long therapy of blood thinners. As for the post op. Our hospital recovers heart surgeries right in our cardiovascular intensive care unit. We do not reverse anesthesia, we let our patients wake up on their own. Because of this, we have them on a ventilator until they wake up and are functional enough to breath on their own. We also monitor things very invasively, so there are a lot of lines. We have a Swan Gantz catheter which measures the pressures in the heart, an ART line, which measures your blood pressure internally, and an I.V. that goes directly into your heart called a central venous line. Usually after you wake up from surgery, if all your pressures look good, we start to take out those invasive lines and we get you out of bed. Most of our patients are in our unit for 1-2 days if all goes well. Then we transfer them up to the telemetry floor for a couple of days and then we send them home. Valve replacement surgery is still a major surgery but we do them every day and the majority of our patients come out of surgery just fine and are home in a week.
- Q: i have seen the wrting M/T on some valve covers and was wondering what that meant
- It stands for the manufacturer; Mickey Thompson
- Q: My third valve is always sticking, despite the fact that I oil them thoroughly every other day. It scrapes the sides of the case when I take it out/put it in, it's almost as if the valve is too big for it. Often times it will stick and I'll have to unscrew it and physically pull it out for it to be functional again.I've inspected it, and the inside looks just like the others which are fine. I've tried washing it, oiling it, and putting a trace amount of vaseline on it. What is the problem?
- Check the spring and plastic valve guide on top of the spring. I've seen these stick and the results are quite annoying, but once the spring moves up and down freely, so will the valve.
- Q: okay i have a 1990 plymouth laser. it runs very and the compression is good but it smokes. im thinking valve seals? Also i need to know the tool to remove the seals. Thanx
- Could be, but first I would change the PCV and the hose going to it. At 18 years of age, it's prolly not pulling out the blowby. To chance the seals, you need a air line and a fitting that fits into the spark plug holes and a pressure line.
- Q: what do the doctors do and is it dangerouse? aslo how do you get a cloged valve?
- Are you referring to heart valves? They don't really get clogged, but can get calcified and what we call stenotic (the area through which blood flows is reduced). There are ways to manage valvular heart disease with medications, but some people require surgery and valve replacement. There are mechanical and biologic heart valves that can be put in place of a damaged valve. The surgery is one of the riskier ones, because it's on the heart.
- Q: here are pix's i want to no, if there is a easy fix or does it have 2 b machined thanksi think it use to have a bent valve in it
- hard to tell looking at your pic,s. your best bet is to find a trust worthy machine shop...they can tell you if they can be lapped or if they need replacing...newer heads have hardened valve,s seat,s..if damaged they should be replaced ...valve,s , seat,s , guide,s , valve seal,s , possible rocker assembly,s , lifter,s , push rod,s ,Etc......best of luck!
- Q: How would this affect the functioning of the heart valves?How would this be detected in a routine examination?
- Endocarditis is usually caused by bacteria. When symptoms are prevalent, blood cultures are done to detect what sort of bacteria is present. Many types of bacteria can cause endocarditis. Normally, blood flows smoothly through heart valves. But if they have been damaged, by some other medical condition, defense mechanisms (such as white blood cells) cannot enter the valves. Then bacteria can have a chance to take a hold on these valves. So if bacteria establishes a hold on the valves, the body cannot get rid of them. Antibiotics can be used to treat the infection. If antibiotics does not work, then the infected valves are removed surgically and replaced with transplants or artificial valves. I hope this helps. good luck
- Q: My 3rd valve keeps getting stuck when i play it, i have valve oil, but its just not working, help please
- There are several possibilities. You may have buildup on either the valve or the casing. Cleaning it thoroughly should normally remove it, but every once in a Blue Moon it pays to take it in and have it professionally cleaned. They can inspect it at the same time and tell you if you have a bend or a ding in the casing. Sometimes they are really hard to spot, especially if they are hidden in one of the crevices of the detail work. A really good repair person can stick a scope down there and tell you if you have some kind of blockage in just a few minutes. The only way to really clean inside the casing yourself is to get a good bottle brush that fits inside with just a little bit of resistance. You should really get someone to show you how to do it the first time because you don't want to go scraping up the insides. There is one other possibility that is kind of rare. Sometimes you get some gunk up under the valve button and it sticks when you push it down. You should normally be able to see this just by looking underneath however. Best of luck and I hope you find your sticking point and are able to set it free.
- Q: I jsut got my valve cover replaced on my car what does that do?
- It just covers up ur valves. Keeps them from getting damaged by other moving parts. And you could say that it keeps most of the oil in it so that the valves can be lubricated. Valves are moving parts so yes they do need oil to help reduce heat and wear!
