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:what do the doctors do and is it dangerouse? aslo how do you get a cloged valve?
- Are you referring to heart valves? They don't really get clogged, but can get calcified and what we call stenotic (the area through which blood flows is reduced). There are ways to manage valvular heart disease with medications, but some people require surgery and valve replacement. There are mechanical and biologic heart valves that can be put in place of a damaged valve. The surgery is one of the riskier ones, because it's on the heart.
- Q:Ok I recently changed my pcv valve and today when I was checking my spark plugs I noticed and valve that looked exactly like a pcv valve on the passenger side valve cover iam not sure exactly what this valve is ?? I should note that I changed the pcv valve on the driver side because I noticed that it was just a hose coming out of a rubber grommet and into the back of the carb was that just a breather hose ? Thanks in advance for any info
- to add, support, you can simply soak pcv valve in fuel. the little eliment filter as well. pcv valve is a hard part. rattles when shaken? it's good. elliment filter is not a paper one. it too can merely be soaked. i've seen a few pcv valves that are bad. those were on engines that sat in yards for years and years. oil dried and set. had ridges that did not let the ball rattle. other than that, never seen one go bad. just need cleaning.
- Q:What are the requirements for valve automation?
- Some valves are controlled to maintain a fixed pressure on a system. Others control the level in a tank or vessel while still others actually control the flow rate in a pipe or line. The automatic control of flow through a valve requires a sensor to determine if flow is needed or what the flow rate is. You then need a controller to take this input and then adjust the valve to achieve the desired result. This is called a control loop. Some are all electric/electronic while others are all pneumatic. The valve itself is a specific valve designed to perform the function intended. It is not a good idea to take an existing on/off valve like a gate valve and try to control flow. These type of valves do not have a flow characteristic that is proportion to valve opening while a control valve does.
- Q:I have a stainless valve I want to install in a copper domestic water line. My concern is: are the two metals compatible? Are stainless steel and galvanized steel compatible?
- I am a bit confused. You ask about nnecting Copper to stainless steel, then ask if Stainless steel is compatible with Galvanised steel. However to join Copper to stainless steel , you will need a special Flux which is only obtainable from a Plumbers merchant. That is if you need to solder them Together. If you dont solder them, Then , yes they are compatible.
- Q:Help! I've got this leaky CPVC valve in a new plumbing setup for a water heater. It only drips when open. :( It's going to be a real pain to replace it. Is there any way to tighten this thing up? It looks like there is a plastic pop off panel on the knob for the valve but I'm not sure. Thanks for any help!
- Turn off the main water to your house. Turn that valve to open. Then tighen the nut on it (slightly), see if the valve will close , if yes; then tighten it a little more, then see if the valve will close. If yes - that should do it. If the nut is so tight that the valve will not close, then loosen the nut just a tad. That should do it, ......... now, turn the valve off. Turn back on the main water to your house -- and see if that works.
- Q:Hey, ive got a scooby and have a baileys dump valve that is a loud deep wooooosh sorta sound. What dump valve does the more high pitch sound? also they dump valve with the higher pitch seems to need less presure ta dump, mine needs alot of pressure before it will dump loud?
- if i remember rite you can adjust the control settings for your dump valve so that it will dump at a lower pressure and a lower pressure dump should also give you the sound that you are looking for.
- Q:I just got my water pump replaced on my Peerless boiler. Now my backflow valve is always dripping. I am unsure if I should cap it off or if the dripping will stop over time. It seems that there is some pressure comming from the vent. What should I do??
- They are like any valve that may not have to operate in a while, sediment in the line gets caught in the seat of the back flow preventer when pressure has been lost to one side. The valve can be disassembled and cleaned but is not for the novice unless you have a lot of time. You can cap it for now but get it repaired or replaced because you will have little protection in keeping boiler water from your drinking water if the pressure is lost.
- Q:What would be some drivability issues with an EGR valve that is acting up. The valve in question is an electronic egr valve.
- i have a egr valve,the same as you,but mine is leaking vacuum.i got 2 new gaskets,but the weather isnt on my side.your trouble sounds like my trouble,and i was told by a mech.,that its the electronic egr valve.
- Q:What exactly are valves and cylinders when talking about car engines? Say a car has 3 cylinders or 8 valves for example.
- There are intake valves and exhaust valves. On the intake side, the intake valve opens which lets the fuel/air mixture into the combusion chamber. At some point (measured in degrees of crank rotation) the intake valve closes, the air/fuel mixture is compressed and ignited by the spark plug. Then the spent mixture exits the cylinder when the exhaust valve opens. Valve configuration varies somewhat, but regardless of how many valves there are there will always be at least one intake and one exhaust valve. Some cylinder heads have 2 intake and 2 exhaust valves which is what is described as the 4-valve per cylinder setup. Regarding Car Cylinders, the answerer says Cylinders in a car engine are pretty much like rowers in a boat. But they are not. Rowers always row in synch with each other. Cylinders are made to be out-of-sync for smoother operation. The more cylinders you have, the smoother the engine runs. Compare a 1-cylinder minibike with a 4-cylinder motorcycle (both air-cooled), or a 4-cylinder to an eight... big difference in smoothness.
- Q:What is the functional difference between the following:1. Blow Off Valve2. Dump Valve3. Bypass Valve4. Diverter Valve
- The blow-off valve releases boost pressure into the atomsphere when decelerating to avoid compressor surge. The dump valve bleeds out compressed air produced by the inertional rotation of the turbo impeller into the atomsphere when the throttle valve is closed. The bypass valve does the same thing as the blowoff valve, except that it recirculates the compressed air back into the intake instead of out into the atomsphere. Diverter valve is just another name for blowoff valve.
