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:ok im 17 and had really bad chest pains for like 2 years and the dr told me last year my valve was leaking and the pains have been getting worse what should i do?
- hcd2.bupa .uk/fact_sheets/html/heart_valve_disease.html#6 You'll probably have to go into surgery eventually. I would suggest seeing all the doctors you possibly can, now, before it gets worse. Try reading through the website above and see if that doesn't help you a bit.
- Q:The timing belt in my 93 honda accord went out going about 45mph,i then paid someone 150 dollars to put in the new timing belt and it began to shake and he told me that the valves were bent.....i went to a local mechanic and he told me that the valves in honda accords dont bend...is this true?and how much is an average cost to repair the valves and pay someone to do all this?can i do it myself?
- OK the valves int eh honda when the timing belt goes will impact the top of the cylinder. Now wether this bends them or not isn't the issue what is the issue is that there is damage to what is called the top end of the engine. A new head, is your best bet. As long as it didn't crack a piston when the valve hit the piston. If you are mechanically able I would go get a used head from a junkyard. go to a shop and have it checked for cracks etc. and have the valves checked. Not necessarily a valve job done unless it needs it. Put that on and that should fix your shaking issue. This is the route I have taken on numerous engines.
- Q:What is the International Standard or other acceptable calculation or table for determine the air supply of pneumatic actuator in shutdown valve 6 to 24.Desired answer will be air flow in SCFM.Thank you.
- Shut down valves I've worked with haven't had an 'Air Flow' for their operation. For the smaller valves, they consist of diaphragm operated valves either held open or closed by pneumatic pressure. The air supply at 25psi to give a diaphragm holding pressure of 15 psi, is via a solenoid valve which dumps the air pressure to either open or close the valve depending upon its function. (That of isolating a system or relieving pressure). The solenoid is actuated by a signal from the shut-down system, and the valve is a 3-way unit which isolates the supply air and vents the pressure off the diaphragm. Other SDV's in my experience, are operated in a similar way but are much larger and are operated by a pneumatic air cylinder and piston with air supplied at 100 psi. Others encountered are ... MOV's...Motor Operated Valves that can be automatically operated from the shutdown system, or Operated Remotely from a safe distance (ROV's).
- Q:1992 Ford Crown Vic, 102K, burns oil, no blue smoke, no leaks. My first thought was a valve job. Any other possibilities? Suggestions? What about an approxitmate cost for the valve job? Thanks.
- Did you check the radiator coolant to see if there is oil in it?
- Q:Cylinder head valves.Can't really differentiate the difference between burnt and just carbon build up on valves. Are they the same?If I the valves have no cracks or holes, can I clean the carbon off of them and reuse them.If they don't leak when I re-leak test them, are they then good to use?Had very little compression in one cylinder.What cleaner is safe to use on the valves?I know I should replace all, but any money I can save right now, helps a lot.Also I seen a method of re-lapping the valves by using a tool (stick with a suction cup on end that sticks to valve surface) that you spin while valve is seated. It refinishes the seat and recreates the seal/re-laps. Appears to work and seal just fine. Anything really wrong with this method?
- Why not just replace the valves.
- Q:What would this envole, can i size up/down the port on the existing valve with just changing the mechanical componts.

- Q:What is the primary 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:what exactly is thc pcv valve and what does it do
- pcv POSITIVE CRANKCASE VENTILATION. this little valve serves as a means of scavenging the blow by gases that have made it passed the rings into the crank case. this valve replaced the earth draft tube on the earlier cars. it extends the life of the oil and improves fuel economy. at idle it is subjected to engine vacuum lifting the valve allowing air to flow through it. at higher speeds and on acceleration, vacuum drops closing this valve eliminating the flow of air into the cylinder from the block. in the event of a backfire, pressure builds up quickly in the hose that goes to this valve, slamming the valve shut eliminating the chance of an explosion inside the engine block.
- Q:Hi, I have Orbit valve for a section of my yard. The pressure is really low when I turn it on with my remote. When I turn it on manually at the valve, the water pressure is much higher.
- Its possible the valve stem is corroded with stuff not letting it actuate properly open. Turn water off and unscrew the valve then actuate it electrically while watching for a full stroke. Make sure flow control is all the way open when inspecting valves stroke. Remember where you had it set when done or readjust. Also check the solenoid for corrosion and clean linkages. I would clean and coat with petroleum jelly. My guess is valve seat is gummed up so lube the stem and work it manually till it slides open and closed easy then test with the solenoid. Good luck!
- Q:whats the location of the pcv valve on on a 2001 bmw 740il (e38)
- In front of the engine slightly to the left and lower area of the throttle valve. It is a round black plastic canister supported by a teardrop shaped rubber with a cable connector at the top and 2 hose connections at the opposite end of the cable connector which are perpendicular to each other. BMW calls it the tank vent valve.
