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:Does anyone know what those valves are/do in my picture?
I have seen this type of valve when it is installed in a location that makes no wet wall access from the back side , one can also adjust the temp a preset safety so one won't get scalded from hot water
Q:Craftsman mower valves?
i can explain it a bit more personally just email me if you want me to i will be happy to help with this sort of problem!
Q:What are the reasons a Schrader valve might need replaced?
After replacing all these parts it should have corrected any restriction. If it was vacuumed out there should be negative pressure in the system and accept a charge through the low side port. If you did not see the actual work done im wondering if the parts were indeed changed?
Q:what are valves in 2/4 stroke engines?
I can tell you right now crazydrunk couldn't have provided the right answer. If he knew what he was talking about, He'd know if the car is advertising the number of valves, and its 16 valves, thats 4 Cylinders, with 4 valves in each cylinder. Two for intake and two for exhaust. The intakes are usually the bigger ones. Simply divide the number of valves by 4 and you'll get the number of cylinders. 24 valve is 6 cylinder and 32 valves is 8. 2 stroke engines are commonly found in old motorcycles, lawn mowers, leaf blowers, genorators and small gas engines like that. 4 stroke engines are found in anything that runs on gas and is over 1000lbs, usually and diesel is above that but runs on heat ignition, rather than spark ignition.
Q:Water heater leak around relief valve?
Hi, Unless the valve released isn't seating properly then you're better off to just replace it, maybe it's stuck thats where pressure is being released?
Q:After a bout with bacterial endocarditis, scar tissue often stiffens the edges of the heart valves.?
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:Will a valve adjustment fix the leak of a bad valve stem seals?
Newer cars and trucks nowadays don't need valve adjustments because the valves automatically adjust to its specifications. However, if your car is an old one that needs the regular adjustments, the white-grayish smoke you're referring at can be traced not only to loose valve seals but can also be due to a loose or broken piston rings, a worn out cylinder walls or a detached cylinder head gasket. So do the process of elimination. First, see if it is really due to the valve seals. There's an add-to-oil additive where mixing it with your motor oil can revive old valve seals. Then apply another additive which claims that its oil molecules adhere to metal. After applying these additives and your car continues to emit the same smoke, then by all probability, your car trouble can only be corrected by mechanical repair (which involve huge repair costs) and no amount of add-to-oil additives can substitute for it.
Q:I can't fit my bike pump on to one of my presta valves.?
to apply the adapter, you need to first unscrew the presta valve, then placed the adapter on and pump up the tire, then take the adapter off and tighten the presta valve to close it. I consider the different answer that that's recommended to replace the tubes so as that the presta valve does not come aside. New tubes are inexpensive - approximately $6 or so. you need to purchase a spare, too, merely in case you flat. in case you do no longer understand the thank you to alter the tubes, your community motorbike save can do this for you and clarify the technique so as which you're able to do it your self interior the destiny and sell you the tire levers (and patch kit in case you want) you will ought to do it. reliable success!
Q:What's the different between (P.S.V. & Relief Valve)?
They okorder.com or other relief valve sites for more information.
Q:how to make a 1 way valve?
Creating a proper valve system for the creation of a diving lung is not as simple as you think. You require carefully balanced directional pressure regulation valves. A simple one-way valve (AKA check valve) would remain open and release all the air from the airbag as soon as the airbag was subjected to water pressure.
