High Performance China Pressure Relief Device   .

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:Why would a ball float toilet valve allow air to bubble up thru the water when the tank is full?

Q:how to protect a foot valve?
most foot valves i have bought come with a strainer attached perhaps you should look for that type. if your valve has a strainer you may consider making a further coarse strainer out of a ball of chicken wire and place this over the foot valve assembly(thats what i do for the cold water supply to my house) don't compress the chicken wire very small as it will block up i tie the wire filter on with galvanized wire then i can easily replace it if necessary ps i tried stainless steel pot scourers but they were to fine and blocked easily
Q:***10 points**** Which set of valves closes when the ventricles contract and relax?
Atrioventricular valves close when it relaxes and the lunar valves close when it contracts

Q:How to modify 1986 YZ 125 Power valve?
The power valve is the little metal flap that cover up part of the exhaust port while the engine is operating at low and mid RPM ranges. If you have bored the cylinder and the power valve is protruding into the cylinder, then you'll have to machine off the power valve or use a die grinder (dremel tool) to provide additional clearance. EDIT - If you're ordering the piston that is .040 oversize, then the power valve has to be modified. If you're ordering the .030 or smaller oversize, or the stock size, then no modification is needed.
Q:Severe aortic bicuspid valve?
The goal with every surgery is to get the person back to a normal physiologically functioning condition. Replacing an aortic valve or any valve in your heart will not inhibit your from performing any of your tasks. Almost all people go on to live normal healthy lives. Exercise and even athletic competitions are well within the norms of someone with a heart valve placement. In the 10+ years in nursing, I have never met anyone who needed to be on disability and needed a supplementary income. Hope this helps.
Q:Mazda MX-3 EGR Valve?
Most of the time its not the EGR Valve, this something else. Do you no what code or codes were found ? I've seen the O-ring missing on the PVC valve alot and this trips a EGR code, Check the PVC Valve for the O-Rings or when the engines ruining open the oil cap and check to see if theres a large vacuum there. If so the O-ring is missing.
Q:Valve springs question?
You need to measure your installed height. No guessing here at all. Measure to be sure. If you don't have a valve spring micometer, you can use a std dail caliper's outside jaws. Remove spring, put retainer on, put 2 locks in, and pull up on retainer till it seats in lock groove. Now measure from spring seat on heads to bottom of retainer.. If you have to then you can measure to top of retainer and then measure thickness of retainer and take that off of your total. You have to know the installed height to figure spring pressure change. The 98214 springs has a rate of 411.. That 411 # per 1 inch and rated installed height is 1.700 So you take the amount of change from the 1.700 and X it by the rate of 411 and that's your total pressure change.. Then take or add that to your rated pressure (which is 115 #) and that gives you your new spring pressure So lets just say installed height is now 1.750 So .050 x 411 = 20.55 #, 115 - 20.55 = 94.45 # total seat pressure Now you need to list the cam your running, diff lift needs diff amount of spring pressure ***EDIT*** Thats a .465 lift cam. If your not winging RPMs past 5,000 then you can get away with a 80 # seat pressure spring, 6K rpm you would need about 5-8 # more seat pressure
Q:how do i open the power valves?
remove the carb abd intake manifold, they are inbetween the intake and reed cage. you will have to rejet .
