Product Description:

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:Are There Other Oils For Valves On The Trumpet Unstuck?
Pull it out and try saliva. Always worked for me
Q:ducati valve adjustments?
Well first, you need to get them inspected, and they'll only adjust the valves if it's needed, even at 6k mile intervals, if your valves are still in spec or very close without lobe drag, they probably won't be changed, so check your bill and ask your tech directly if they were changed, some less reputable dealers may try to pull a fast one on you. If you actually needed ALL 16 shims changed, you're easily talking $1000 in labor, esp. on the 748/916 style heads, which have access ports on the heads instead of being able to remove the whole top of the heads like the newer DESMOQUATTRO heads, and are a PITA to work on because of it. The bad thing is that until recently (and they still need improvement) Ducati's quality control is lower than other manufacturers, meaning very inconsistent performance reliability, just from variances in manufacturing. If you get a GOOD tech to do the bike right in the first place though, not just valves but all-important TPS resetting, cam timing/belt tension, and balanced CO's in your exhaust, you will have a lot less headaches with your Duc.
Q:Motorcycle Valve Seals - 4 stroke (what is the function of valve seals??)?
Valve seals are placed over the intake valve guides so oil will not be drawn into the combustion chamber on intake stroke.
Q:Anybody with a valve replacement?Which valves do u think are more successful,mechanical or natural?
Usually with an artificial valve, you'll need to be on a blood thinner for the rest of your life. If they use a natural valve, you usually won't need the blood thinner - perhaps you will for a little while, but not permanently. You can request a natural valve, but the surgeon doesn't know what size/shape of valve you need until he actually opens you up and sees what he's working with. He has an idea, based on the x-rays and MRIs you've had done, but he won't know for sure until he actually see it. So the surgeons are going to request that the Organ Procurement Department to thaw out two or three valves, depending on what they see in the tests. You can't just keep thawing out valaves, testing them, and then refreezing them if they aren't what you are looking for, so if they turn out to not be a good fit, he's going to turn to an artificial valve. So you could request a natural valve, but because of the shape of the gap that he needs to fill, you may have to have an artificial valve. Blood thinners scare people, and your friends will tell you horror stories about how their uncle's cousin's Nephew cut his arm and bled to death because he was on a blood thinner! That could happen, but it is very rare. What does happen is that you will have to go to your doctor once a month and have a blood test, and if your blood is too thin, you need to ease off on the blood thinning medication. Or if it is too thick, you need to take more. If you're blood is too thin, you'll bruise more easily - which might be embarrassing if the bruise can be seen. Blood thinners aren't as dangerous as they make them out to be, but they can be inconvenient!
Q:trumpet valve keys !?
Unscrew the the valve cap on the appropriate under the button. attempt to softly pull the valve out. you may would desire to artwork it back and forth till it loosens up you may upload some oil around the the sting of the valve cylinder. as quickly as you have all 3 valves out sparkling each of the particles off of the valve, you ought to use an sos pad to get dissimilar the heaver stuff off. Wipe each factor off with slightly of lighter fluid and a sparkling rag. sparkling the valve bores including your snake. Stuff a rag down each hollow to get the stuff the snake loosened up. Reoil the valves and the cylinders and reassemble.
Q:what is action stop valve in the steam turbin?
This is a 'Trip and Throttle' (T T) valve that is maintained in a 'Fully Open' postion during normal turbine operation. It is maintained open by a Hydraulic Control system that, should any of many shutdown conditions occur, the hydraulic oil will be dumped to its reservoir by the operation of a Solenoid valve, actuated by the shutdown signal, and the T T valve will immediately close, stopping the steam flow to the turbine speed control steam chest in a safe manner. The valve handwheel is then operated to ensure that the valve remains fully closed until the system is ready for re-start. The valve cannot be opened again until the shutdown condition has been rectified and the hydraulic system reset to restore the oil pressure to the valve. The valve however, can then only be re-opened manually and slowly until the turbine is brought to the 'Minimum Speed Control' Governor setting. When settled down at this condition and the steam chest valves are under the control of the Governor, the T T valve is swung wide open. This latches the valve in the fully open position until another shut down occurs,
Q:I need to replace the multi-turn valve for the cold water my kitchen faucet. I have CPVC Flowguard Gold pipes
Is the new valve or the old valve the compression type? If the old valve is then as you take it off you will discover if it is glued (I doubt a compression valve is also glued). Replace the old valve with the same type as the old one. That is always a good rule of thumb to follow. Put it on tightly but DO NOT over-tighten it. 1/4 turn past tight it usually tight enough. I am not a big fan of compression fittings in either copper or cpvc. You may wish to put a glued valve on, if you already have the cleaner, the primer, and the glue, other wise the expense of the materials does not warrant their purchase for the changing of one valve.
Q:Is there a difference between the two valves in each side of the heart?
Atrioventricular valves separate the atria and ventricles. Mitral valve has 2 flaps which separates the left atria and the left ventricle, whereas tricuspid valve has 3 flaps which separates the right atria and the right ventricle. I think there's only 1 pulmonary valve, which is located between the right ventricle and the pulmonary artery. Pulmonary valve and aortic valve, which lies between the left ventricle and the aorta, are two semilunar valves.
Q:what are valves in 2/4 stroke engines?
To give you an example: my car has a 4 stroke Otto cycle 4 cylinders engine. It has 16 valves. Every cylinder has 4 valves, 2 to intake fresh combustion fluid ad 2 for the exausts. It's a double over head camshaft engine (DOHC). A 2 stroke engine doesn't have valves as a 4stroke. In a 2 stroke engine (in Otto cycle, I don't know in Diesel cycle) the piston works as a valve. Take care
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?
