High Performance China Pressure Relief Device .

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

♦ 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: It is burning oil, so that means oil is getting into the combustion chambers....but im not exactly sure which piece has gone bad? or for that matter what the valve guides are in the first place. Could the lifters have gone bad too? Can someone tell me what piece is most likely the cause for the oil leak into the chambers and then a price of how much it would cost to have it fixed. When i start the car it blows a puff and then settles down and then when im at a stop light and push the accelerator it blows a puff and then more or less settles down...sometimes it keeps going for a while. My mechanic put an additive in the oil called stop the smoke or something, and i know that that causes the seals to expand...and it has helped. So. I need someone to give me an overall diagnosis and price range. My mechanic is reluctant to have me do the work, im guessing cause its expensive...but i would rather pay 1000 dollars then buy a new car.: yes we would love to help, except you gave us zero information, in order to even begin to guess whats going on, you need to explain a whole bunch of information if you want any help, like what year make model of car, engine mileage on engine, and any other things that have been done to a coar that you know of. If you have a chevy 350 it was pretty normal to get a puff of smoke out if it when it was cold, this was from worn valve stem seals, and sometimes the design of the seal was a problem, like the umbrella seal for late 80s early 90s, even new some got a few drips of oil and blow a puff of smoke, you say its smoking out the tail pipe, ok when only when cold? or all the time , or under acceleration? when, that is the first clue we need to know ok?

Q: Valves regarding WC's: A flush valve (if you are talking about a toilet) is the flapper at the bottom of the tank. I suppose it could also be called a drop valve. At any rate, a flush valve is designed to rest in place preventing water from passing. When the flush valve is raised, trapped air in the bell of the flapper will cause it to float as high as possible, allowing water to pass without restriction. When the water level is low enough the flapper will float back down and seal the opening, thus allowing the tank to refill and be ready for another flush. Good luck. :)

Q: My brother bought a trumpet last month, and I've been trying it out but the first and second valves keep sticking. We've tried valve oil, but it isn't working. Any tips?: have you tried washing it out? ive played instruments i was going to suggest valve oil first but if that didnt work theres a good chance it needs cleaned inside and out and then oiled.

Q: I have a 1994 Toyota 4x4 pickup with the 4 cylinder motor. How do I check to see if the pvc valve works?: pull the pcv valve out and shake it, if it rattles, its good, also check to see if its working. start your truck and check for suction, by putting your thumb over the valve, if no suction, take the hose off and clean out the hose and fitting, its probably clogged up.

Q: HI ever one i have a 1969 1500 beetle engine i have just but 1600 piston and barrows on it but when i but the rockers on i have no valve gap at all. ive wound out the adjusters all the way and i still can not get a feeler gauge between the rocker and the valve. Please help cheers Adam: The problem could be that the crank shaft has not been turned to the place to adjust the valves. The push rods could be the wrong length ones too.

Q: I have an '03 vw jetta and don't know if I should get a greddy blow off valve or an injen cold air intake? Any suggestions? I don't know a lot about either, what is the difference between them?: a cold air intake will produce more hp and tourque while a bov will help release back pressure on a turbocharged vehicle. ive got a 1.8l turbo and i went with a cold air intake. then again i was going for more hp. also the bov will produce an awsome release of air into the atmosphere. then again if you get the air intake like i did you will hear the wastegate on your turbo make that same noise. and trust me itll make some ppl think you got major hp under the hood. so if you want the hp and the sound get the intake if you want the sound but are satisfied with the hp get the bov. intake will also help mpg's to.

Q: does anyone have a bicuspid aortic valve and wrestle? my cardiologist told me that wrestling would put too much strain on my heart but i can feel that i'm fine when i wrestle so if you have a bicuspid aortic valve and wrestle or know anyone who has that disfunction and wrestles please let me know: I was only recently diagnosed with a bicuspid aortic valve, and before then I had wrestled for 13 years. I think every case is different though when it comes to how severe the stenosis is within the valve. If you really want to wrestle, you should ask your cardiologist if there is any way you can strengthen your heart to the point where he thinks you will be able to wrestle. Another thing you can do is try and wrestle, but pay attention to any chest pains. at the first sign of chest pain you should stop, immediately. This is nothing to screw around with.

Q: My fortuner stalls without warning, but restarts quickly, according to Toyota service center, we need to replace the suction valve, can someone please tell me how a suction valve work: you need to be more specific. there are 100 things on a car that could be called a suction valve. Right off the top of my head the only valve that could do that is a EGR valve. If it gets stuck open the car will stall, but it will start back up after the valve closes again. The OBD will tell you if the EGR valve is bad, but other than that I can't say.

Q: How would you change the Heater control valve on a 1997 honda civic hx?its my first car, so i dont know much about cars.: the heater control valve is in the heater hose under the hood. on the passenger side of the car there will be two heater hoses going into the engine wall. one of them will have a heater valve in the line with a cable attached to it. drain the coolant from the radiator before removing the heater hose or you'll get coolant all over the place and coolant is toxic to animals. after you drain the coolant you can remove the clamps that secure the hose to the valve. have a drain pan under the car as some coolant will still be in the lines. once you remove both clamps you can take the hoses off the valve then disconnect the heater cable. install the cable on the new valve and install in the reverse order. fill the radiator back up will the removed coolant. you'll need to run the engine until the thermostat opens and the coolant level in the radiator drops. then top off the coolant and put the radiator cap on. hope that that helps
