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:when riding my motorcycle valves start knocking i took to a mechanic and they did not resolve problem. i have baby ed my motorcycle. dint know what to do at this point and time.
A lot of times you will not hear a valve problem, They tend to tighten up with age not loosen. On sign of a valve out of adjustment is if bike is hard to start when cold. knocking could be loose timing chain, timing chain tension-er needs attention.,Could also be worn drive chain. It will make a popping sound when its stretched out. Some front brake calipers will make a knocking sound, its the pads rattling around between calipers and rotors.
Q:what do the doctors do and is it dangerouse? aslo how do you get a cloged valve?
they are dangerous and you get them sometimes form cholesterol and stuff, the doctors clean it out sometimes unless you are in real danger when you have it removed
Q:So I know the main purpose of the EGR valve is to recirculate some exhaust to the cylinders to reduce NOx emissions. However, a mechanic told me that a malfunctioning EGR valve can make the engine run way hotter, and that this can damage the pistons, or other components of the engine, over time. Is that true?
Yes, very true. It would help if you stated what vehicle it was for. But let's say it's a Ford F-series truck with the 6.0L diesel, highly known for this problem. You can actually purchase an EGR delete which actually bypasses the valve so it won't burn the piston rings (the actual part that burns up). Buying this item only costs a few hundred and will save you thousands in the long run.
Q:I heard alot about blow off valves making your engine run rich, but I want to get a blow off valve or bypass valve when I get a wrx. (I know some people think they're gay) but i dont care how loud it is, just want that sound. so what's the difference? I've been looking at this one:

Q:Valves regarding WC's
David, tercir is wrong. A flush valve is THE valve inside of a toilet tank that allows water to refill the tank when you flush your toilet. That flush valve has a float on it so when the tank refills to a certain point, the float shuts the water off. A flapper valve merely HOLDS the water in the tank until you flush the toilet. The flapper valve is the thing on the bottom (inside) of your tank that covers the water outlet. When you flush your toilet, that flapper raises the water that is currently inside of your tank, is what refills your toilet bowl when THAT water goes down into your sewer system. OK?
Q:my check engine light just came on and i have some oil on the block of my engine, a friend told me that the valve cover gasket needs resealed. could that be why my check engine light is on?
I changed my vavle cover gasket over the weekend and my check engine light had been on....it is now off. That is the only repairs I have done. I was informed it could be my catalytic convertor causing the check engine light so i have ordered that. However with the light off.....idk lol
Q:what is meant by inherent characteristic for the steam control valve??
There are different type of valves, (ball, gate, globe, needle, diaphram) each have their own characteristics in how they operate and the effect they have on flow. Inherent characteristic would be an effect that valve has on the fluid flowing through it.(steam can also be considered a fluid ) An example is a globe valve used to throttle a flow does so by adjusting the size of its opening. In essense its a variable orifice. Flow through an orifice results in a pressure drop across that orifice. So, an inherent characteristic of a globe valve is a pressure drop.
Q:I was woundering if anyone had a repair manual for this valve on a 2004 Nissan Maxima. I just bought the car and Im getting the P1800 Code. Any help would be appreciated!

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.
Q:I own a 2001 Chevy cavalier Z24 with a dual cam... Just got it tuned up and noticed oil in my spark plug sockets, which leaves me to assume either the valve cover gaskets or the cam carrier gasket is leaking oil... I would prefer to so this by myself considering I'm sure it's going to be costly.. Anyone have any ideas on how I go about replacing either?
valve cover shouldn't be that much of a problem as long as you have some basic tools and some mechanical ability. Take it that its a 4 cylinder car, the size of the motor is very helpful when looking for tips. Just don't over torque your bolts when replacing. 89 in lbs is about normal on gm's valve covers
