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

♦ 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.

♦ 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:I live in Houston (where it hardly EVER freezes during the winter..) This winter it froze and the valve on the sprinkler system flew off and water started shooting straight up. Now that it's getting warmer and I'm going to need the sprinkler.. I have to repair it. Is this an easy fix that I can do myself? Or should I call someone.
- If okorder /... If the brass body of the backflow cracked, then you will need to replace the whole thing. That link above has the best prices for these things. Good luck!
- Q:I need to find a solenoid valve with the following specifications:2-way, 1 inch nozzles (both male)needs to be able to handle the pressure from a CO2 tank (~1000 psi)needs to work with 12vdc less than 10 ampsits either a solenoid, or some other type of valve which will release the CO2 when we tell it to electronically
- The leading maker of solenoid valves is ASCO. Their website is shown below. If a valve that fits your application exists they probably make one. If you can't find a suitable solenoid then you need to consider a pneumatic valve operated by a solenoid valve. That is a common solution for a problem like yours. As to the male connections. If they are not available then you can just use a pair of threaded fittings (pipe nipples) to change the configuration.
- Q:I just dropped my 3rd valve slide from my trumpet on the ground. It fell with the curved end first. I can't see any dents and it doesn't look bent, but I oiled it and everything and it's really hard to move. Could it be bent? How can I fix it?
- Be sure that it is aligned correctly when you place it back in the valve casing. When you are putting it back in, it has to turn until you hear a click, indicating that the valve guide has fallen in the right space. This aligns the valve with all the ports. (The valve guide is a small plastic piece located under the valve spring. This valve guide must snap into a little notch inside the casing. When it does, the valve will be perfectly aligned. You will know when the valve guide is in the right place because you will feel and hear a click and the valve will not rotate any longer.) After thorough cleaning, oiling, and correct valve placement, if you still notice it sticking, take it to a repair shop to have it chemically cleaned. They are typically very good and will ensure your trumpet is in proper playing condition.
- Q:I Have a 2001 Honda Accord 3.0 V6. Would a clogged EGR valve cause it to run rough and have problems starting up when it is warm? It also runs hot. I have replaced the thermostat and the cooling fan relay? What could cause all of this? PLEASE HELP!

- Q:I've never replaced a shut off valve before but am wondering if there are any tricks in freeing up a stuck valve that wont close. Can this be done so I don't have to call anybody?
- turn off water to house, if your valve has a nut behind handle that has threads on inside of nut ie brasscraft style, you can go to store and buy new valve and replace stem. If pipe comes out of wall (angle stop) get that one, if comes out of floor (straight stop) get that one. remove new stem and old stem and switch. If nut behind handle has threads on outside of nut, then you must replace valve. ( you have to remove nut to see where threads are ( i don't but you might) depending on what type of pipe you have is what new valve you will need and also how close to wall or floor is how to attack problem tre..706yahoo 4 any more help
- Q:I am trying to repalce the water turnoof valve under my sink but the valve just keeps turning and no progress is made to get it off so I can put on a new one. I am turning it clockwise but it just keeps turning. Can someone please tell me how to get this off? I do not want to have to call a plumber for something that I might be able to fix myself.Thanks.Sandy
- firstly turn on your kitchen sink tap then turn stopvalve a bit at a time someone may have fitted the wrong valve and it only needs a 1/4 turn to shut it off .if this is not working then your stop valve head or shaft may be worn and just turning, in this case you can only freeze it or turn off in your garden or street .if you are talking about your main stopvalve then to comply with water regs it should be fitted with a double check valve /drainoff and mains stop valve.p.s expect water it is like traffic wardens appears from nowhere.
- Q:Water is seeping up around relief valve threads. Tried tightening but could not get it any tighter.
- lift few times pressure relief release, just to check if it is not jammed and it is not holding too high pressure. 1. prepare thread tape or goo, if no experience - goo is better, available in hardware and plumbing stores, you need just few drops 2. cut off water supply to the heater 3. relieve pressure in the heater (just open any hot water tap (fawcet) and let water out) 4. remove the valve completely, 5. with wire brush clean the thread, check for damage to the thread on the cistern as well and clean it too 6. wind several layers of teflon tape or well grease with plumbers hot water goo 7. remount the valve 8. close hot water tap which was used to release the pressure 9. open water supply to the heater 10. open hot water faucet to let the air out, close when stop gurgling and water pour out 11. check for leaks, if no leaks - JOB WELL DONE! 12 if any leaks find, repeat 1 to 4, wind few more layers of teflon tape, if goo was used - you need to use tape as well then. 12. repeat 7 to 11 and that is all...
- Q:I know what a blow off valve is but where does it blow out the air out off does the air blow out threw the exhaust or what?
- Depends on the type of blow off valve. Some vent to atmosphere(just blow it out into open air) others recirculate(blow the air back into the intake farther upstream). Which one it does depends mainly on where the blow off valve is located in the system. If the car has a MAF(mass air flow) sensor and the blow off valve is located after that sensor then it has to be recirculated, because the sensor has already registered that air and if it vents to atmosphere then the engine will run rich because the ECM will be putting too much fuel into the engine.
- Q:Anyone know where the pcv valve is located on a 2000 Lincoln Ls V6 3.0
- find the valve covers and it's on one of them, it plugs into the valve cover and has a hose running to it, take it out and shake it and you should hear a ball bearing rattling noise if it's good.
- Q:The check engine warning light came on in my car, i went to pump gas and try to start but it wouldn't start. I went to the dealership to let them check up, and they said the problem was the purge valve, it leaked. What is a purge valve and what does it do? Is it common for purge valve to go bad?
- the purge valve as it was refered to is in ur fuel pump on ur car and yes this happens offen when ur fuel pump is in ur fuel tank u should never run below about hafe a tank on a hot day because your fuel is what keeps ur pump from heating up and when u run low on fuel ur purge valve can over heat and warp hope this helps good luck
