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:Leaky Toilet shutoff valve....?
After replacing hundreds of these I suggest that any cost of the mentioned fixtures is far less than the resource wasted. I'd begin with a new shut off,,,inexpensive and easily installed, once the main line has been temporarily shut off. Then as long as it is, replace the line as well. I suspect at a cost of less than $10 for both. Often the issue extends to how YOU might have threaded both, how tight, within reason you secured them, and this is so common you should be able to alievieate the poroblem by replacing,,,, as long as you consider cross threading and possibly threading metal components to plastic. On an environmental note, Constant running is wasteful, and certainly damage to any flooring, or walls/molding that sponge up any leakage are wasteful in an after effect. Steven Wolf
Q:Proportional valve problem?
no count number if it incredibly is a proportional valve a 24 volt supply won't supply proportional administration. to boot, controlling an inductive load with a persevering with voltage slows the reaction time.
Q:Where to get Electric Valve?
ASCO okorder.com is another vendor, though Grainger is good. If your budget is tight you could remove one from a dead dishwasher or washing machine.
Q:how to adjust valve lash on a gmc yukon?
remove valve covers, watch front left two lifters and turn engine, by bolt that holds harmonic dampener to front of crankshaft, so mark on dampener lines up with mark on front cover. If rocker arms do not move as marks line up engine should be on top dead center number 1 cylinder. Now you can adjust exhaust valves 1, 3, 4, 8 and intake valves 1, 2, 5, 7 [ odd numbers are on the left bank from the front 1,3,5,7 even on the right bank from the front 2,4,6,8]. Adjust by turning nut in rocker arm out until movement is felt than tighten until all movement is gone and tighten one turn more. After done with the first eight valves turn engine over one full turn till marks line up again. Then adjust exhaust valves 2,5,6,7 and intake valves 3,4,6,8 the same way.
Q:engine piston valve question ford ?
in case you have a broken valve, the broken element will probably destroy the cylinder and piston in case you run it that way. ought to easily be a flaw in the unique valve or another ingredient, no longer person-friendly to appreciate.
Q:Controlling a butterfly valve?
Edit: the fast literal answer is no with the aid of be conscious in basic terms. each sort of valve may well be usually considered to be a pass administration device. maximum styles of valves, gate, globe, ball, B'fy may well be manually set everywhere from finished open to totally closed and can be set to any in part open place. The term administration valve usually refers to valves, which comprise butterfly types that are immediately regulated to modulate a cost of pass in accordance to a administration sign to the valve actuating device. in specific circumstances the sign is from a distant sensing element such with the aid of fact the temperature sensor controlling a refrigeration expansion valve. sometime the sign is from in the actuating device itself as in a water rigidity regulator on your place city water grant. The sign itself may well be modulating , as above or that's on/off which includes an emergency shutdown valve on a steam turbine or the on/off valve on your washer.
Q:Trumpet Valves Question?
PING ! You probably have a minute dent in the valve casing that the eye cannot see.. A repairman will buff it out . Meanwhile it is abrading the valve ( like a car cylinder ) so make haste to the repair shop.
Q:After a bout with bacterial endocarditis, scar tissue often stiffens the edges of the heart valves.?
If the heart valves are damaged, they may leak, causing regurgitation of blood. For example, if the mitral valve (between the left atrium and left ventricle) leaks, blood will leak back into the left atrium when the ventricle contracts. This reduces the efficiency of the heart contraction. Regurgitation is easily detected by echocardiography. On routine physical exam it may be detected *if* there is enough leakage/ flow abnormality to cause an audible sound, or murmur, that your physician can hear with his/her stethoscope.
Q:what is a valve job? i was trying to sell my Honda CRX, but the man said that the valves dont sound good...?
Basically a valve job is a valve backlash check and adjustment. There has to be a clearance measured in thousanths of an inch between the camshaft and the rocker assembly. This is generally measured with feeler guages.
Q:I can't fit my bike pump on to one of my presta valves.?
If is it a deep V wheel you need a tube with the proper extension for the value, or a presta valve extender. Next time you replace the tube measure how long the value is in mm and get a tube with a longer valve stem.
