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 Auxiliary Air Valve on my 98 Civic?I have a 98 Honda Civic ex and need to change the Auxiliary Air Valve
- l was told by a mechanic that I had a bad auxiliary valve and I would cost $1200.00 I can t find information on such a thing. Douglas
- Q: Where are the valves. And how do I fix it? Will I have to buy anything? I have a 98 Honda fourtrax 300.

- Q: Is there anyway, from home, that I could rule out a bad heart valve as the cause for my heart palpitations and arythmia?
- As a physician, I strongly recommend you to visit a ER (Emergency Room if you were from UK) and explain the doctor what is going on. I also would recommended ACE inhibitors, since they prevent cardiac muscle remodelling. I can think in several other things, but I need PE and a new echo-cardiogram to make a decision (indeed a ER doctor must make those decision)
- Q: How many valves are involved in th etypical 4-stroke cycle? Is it the intake and exhaust valves only? If my car engine has 12 valves, how many cylinders does it have?
- For basic internal combustion you only need two valves, one for intake and one for exhaust. The four strokes are referring to the piston moving up and down in the cylinder, one to take in gas and air, one to compress the mixture, one during combustion and one during exhaust. Common cylinder amounts for cars are 4, 6, and 8. Some Volvos had five cylinders, and exotics can have more than 8. Modern engines can have more than two valves per cylinder but the standard is still two, so if you have 12 valves you most likely have a 6 cylinder engine.
- Q: im 16 and im rly scared i have already been checked out by the hospital and they sed that i have a moderately leaky heart valve. They recommended me to see a childrens cardiologist since they dont specialize in children. i have to get another echo and some other tests done i think. im so nervous. whats going to happen to me??
- dont mind buddah ,youl be fine 1 in 5 people have it and never know but you can live a worry free full life just like anyone else as long as you look after yourself
- Q: Does anyone know where i can get a chromed valve cover for a 99 eclipse or is there a way that i can do it myself? id like to get one that has the etched 2.0 and DOHC words on it
- Usually okorder /_... Their pricing is decent and the quality of their work is excellent. They are also on OKorder and have a core/exchange system setup. I'll leave some links for you to check out in the source box
- Q: also are those air flow limiting valves safe for the air pump to reduce the flow of air, I have one because the air bubbles are just way too many without one and it scares the fish away
- a check valve is to prevent back siphoning of water into the pump if you have a power outage or unplug the pump by accident. I'd suggest checking it by blowing through it the wrong way; if air does pass through get a new check valve (check new ones to be sure they don't limit airflow too much, and that the close in the wrong direction, many are cheap crap and don't work the day you buy them, so check them before you leave the store with it...note: same with thermometers, compare them with each other so you don't get the one that's crap) what you want is a normal air valve, they come in various configurations, one or more valves so as to run multiple airstones and to balance the airflow to each stone or ornament. You should not however just use the valve to limit airflow, as this damages the pump eventually. You can just let one of two valves bleed off a little air; however make sure another check valve is in the line from the tank to the valves or else you risk water coming out of that valve if it's lower than the tank water level.....You may want a smaller air pump or an adjustable one instead.
- Q: And' the valve leaks......Can the valve be unscrewed from the tank for replacement? Or can the valve be serviced with a new gasket perhaps?
- Go to the following site and enter the Model of your water heater in the box provided Click on the Magnifying glass. This should give you a list of all the parts for your water heater.
- Q: about a year ago a bought a bach stradivarious. the valves aren't sticking, but they are still considerably slower than my ten year old omega. shouldn't they be broken in by now? i've cleaned it countless times and tried many different valve oils. any tips on how to get them faster? thanks to all!!! :)
- Despite okorder and ask for recommendations based upon your location. It's a good bunch of guys who will steer you in the right direction.
- Q: like my Acura has a 16v 4clyinder engine , and i dont know what valves does , the more vavles the faster?
- Valves are in the Cylinder Head, They let Air and Fuel into the combustion chamber. 4 vavles let more air and fuel in than 2 vavles, Which makes more power.
