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: Hi. I replaced my PCV valve but the hose it connects to is cracked at the end. It's still loose and I can pull it off with my hand. It is very hard to get it to stay connected. So my question is that while I am driving, what would happen if the PCV valve accidently disconnects from the hose? Would I still be able to get to a service center?
- Depends on the vehicle, most cars may run rough, sluggish, some wont even run, every car is different on how much actual vacuum is running through the pcv valve that will determine if its drivable. Run it for a minute..drive it around the block make sure it wont die...then take to the shop.
- Q: Alright. The engine is a 7mgte. The clearances for the skims in the intake side is 0.20mm and the exh side is 0.25mm. What happens if i mixed the shims?
- What do you mean if you mix the shims? Like switch the shims between the two valves? If that's what you mean then you could be causing the clearance to become really small on one side and really big on the other. Just check the clearances with the engine at TDC or on the heel of the cam lobe and you should be fine. The tick tick noise would either come from to big of a clearance or no oil. So I guess the simple answer would be nothing would happen if you mixed the shims except the clearances would change. Thumper This engine doesn't use pushrods or lifters. The cam pushes down on the valve with with shim overbucket design
- Q: Bought a 1986 GMC 350day 1 started up good - idle was rough - idle really too low, when brakes where applied, it would backfire. (day 2) Changed oil which was really dark - oil filter too... ghanged spark plugs and wires. % 10 improvement... Engine lack power and vibrates but no more backfire.day 4 Changed Cap and rotor - % 30 improvement - day 5 Got the manifold gasket replaced. Same condition but silent... day 6 Changed coil in cap ... Changed fuel filter % 60 improvement... The thing ran like new... Full power I started beliving again..Got full oil pressure 300 kpa - no valve noise Ran 30 minutes on highway.... Valves started making noise especially on driver's side... Engine lost lots of power, and vibrates a lot... doesnt heat up to much but oil pressure seems very low. (day 7) Start up the thing, and even when cold and choke on, oil pressure not as good as in the beginning. What went wrong
- I never got to scan any coeds when I worked at AutoZone! There were a few colleges nearby that had plenty of them. Sounds more like you have some carbon built up around your idle air control motor, or the motor may be bad itself. It is located on the side of the throttle body. It is a small passage blocked by a small step motor that pulls away and allows more or less air past the throttle blade, thereby regulating the idle. Throttle position sensor can cause similar problems. Clean the motor and air passage, and test.
- Q: Among butterfly,ball,needle and gate valves which is used mostly in pneumatic system?
- I don't agree that gate valves operate quickly and that they usually don't leak. Gate valves are slow to operate specially in large sizes and they all tend to leak unless they have a soft seat and there are very few of these type of gate valves. In larger piping systems globe valves are used to throttle air but not usually as a on/off valve. Probably the best on/off valve is the soft seated ball valve. They work well regardless of size with very little if any leakage. You can get some butterfly valves with soft seats that are really designed to operate much like a ball valve but are only economic in large sizes. The disc in these valves is essentially a wafer out of the sphere and that is why they do so well.

- Q: im just bored so heres my question who do you think is better valve games (hl2 tf2 css) or bungie games (halo) and why. whoever gives me the best reson gets best answer. personally i like valve
- Really hard question... So I'll start with Valve Valve - Half-Life 2/Ep1//Ep2 has the perfect physics/graphics and grabs you into the game. - You can buy games from their uhhh Steam thing, and I think you can instantly download once you buy. - You can play the most popular CounterStrike where you shoot/meet 12 year olds and other guys. -Most games from Steam that are about a year old become cheap and usually cost $10 Bungie - Halo 1/2/3 just an awesome game. - I dont know much.. so yeah.. The halo series are self explanitory. But Im a valve fan soo yeahh.. its totally up to you.
- Q: Was wondering if there is something I could purchase to put into a car so that it will become a 24 valve????
- Time to drop out of your software then. You did no longer even attempt - you in basic terms decrease and paste an common quiz devoid of even inclusive of the linked diagrams, and anticipate us to unravel it. Why could we do this? you haven't any longer even attempted. i do no longer want you getting close to a motor vehicle in any technical means in any admire in case you could no longer answer those questions.
- Q: I have a lawn tractor with a 10 hp Tecumseh and its running so rich because of the carburetor float valve not seating. So how should I fix this?

- Q: ex: 4 stroke 16 valve engine
- 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.
