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

Q: My AC leaks and mechanic says it is shrader valve. Is it expensive?: No okorder /

Q: I was diagnosed by 2 places that my 1995 chevy lumina needed a new egr valve due to the check engine light being on. I got a new EGR valve but the check engine light is still on. Evidently there is something else wrong with the car. Since the check engine light is still on would you figure that my EGR valve is still good and that the light comes on for some other problem?: i think your right. I'm not sure but a think your EGR valve is vacuum operated. If so, there is a vacuum solenoid to control the vacuum to the egr valve. There is also intake vacuum to this solenoid. Could be no vacuum to solenoid or a bad solenoid or wires controlling the solenoid. But also could be a completly different problem other than egr. You need to go back to the shop that put on the egr valve and find out why the egr valve didnt fix your problem. And either have them fix it right or get your money back.

Q: I recently had an echo and they said their was a slight tricuspid valve leak but it was 19 and anything less than 20 is considered normal. I have no clue what that means. Does any one have and clue on what scale she was talking about. Also she stated that the machine are so sensitive these days that the majority of people are found to have some sort of leak. Is this the case??????: finding on the severity of the valve situation it fairly is severe. If it have been severe you certainly could have indications that could assist you recognize previous to now. Ask the physician how severe the valve insufficiency is. A mitral valve prolapse could make you sense mild headed. The tricuspid valve insufficiency could convey approximately severe issues. There are various circumstances that would reason this. it fairly is great to your heart professional to describe your situation. In any experience it fairly is no longer something to fool around with or placed off. while you're actually not chuffed with the solutions do no longer hesitate to get a 2d opinion.

Q: Com wires attached to com and all individual valve wires are attached. The valves work manually( turn on by hand), I open the valve to allow the box to take over and the sprinklers run. Is this just residual water in the lines??: I would test the leads inside the control box first... You will have to run the controls manually to troubleshoot the problem. Get a voltage meter to test for the 24 volts at the transformer connections inside the box... If you do not have the 24 volts then the problem will be the transformer. If you have the correct voltage from the transformer then you can test each of the station terminals to common. Test through each station to see if you have 24 volts at each station terminal, but you may have to remove the wires off to test. If you do not have power coming from each station… then the problem will be the rain bird control. The next step would be testing the wires… If you reconnect the wires… test just prior at each valve location to see if you have the 24 volts between the common and each station wire… if you can prove out that there is 24 volts at this location then you’re down to the final testing. Reconnect the valves – one side to the common and the other to each station wire… Getting the power (24v) to the valve should have cleared your problem. Good Luck… Running the valves manually will not affect the operation of the rainbird control... but with my rainbird valves.. you can shut off the valves completely and disable the electrical controls of the valve... make sure that you have not closed the valve off manually preventing the electrical side... a problem with rainbird controls. This does not have anything to do with residual water in the lines... I would test this side first before you get into the electrical side... could save you a lot of time.

Q: So it always seems that when I see the jet and foot valve out of a well there's a drop tube between the jet and foot valve. My question concerns this drop tube- is it necessary? I've got a leak somewhere, replaced the foot valve and still have a leak. I'm inclined to get rid of the old drop tube, it's crusty and likely to be the source of leaks either now or in the future. any reason to not just plumb the foot valve directly to the jet? Thank you kindly for useful information.: The reason for the drop tube is to possibly save you replacing a pump. All wells silt in a certain amount. Your submersible pump can withstand a certain amount of this fine silt but if it gets to be half-submerged in the stuff it will burn out. With the drop pipe in place, the foot valve will plug up first, giving you warning and a chance to shorten the pipe above the pump. Rather than fitting the foot valve directly into the bottom of the pump, you would be better advised to replace the drop tube with a new piece. Also be sure to test your foot valve while you have it out of the well. Some are faulty right out of the box. I always screw on a fitting with a snifter valve that allows me to put 150 psi of air on the foot valve over night. If it doesn't hold that, it shouldn't be at the bottom of a deep well; it's just too much darn hassle pulling them.

Q: I replaced the valve cover seal and I wanted to know the torque specs for the valve cover bolts and the sequence it should go: Valve Cover Torque

Q: Can anyone recommend valve manufacturers who make a good electric high temperature valve. The temperature that I am looking at is 1600 F at 100 psi. It should be electric magnetism controled. Is there anybody know what is the highest temperature the valve can bear in the world?: google 'inconnel valve' look for foundry equipment suppliers Can you valve the gas away from whatever is hot, or is your gas at 1600 F and 100 PSI ? If so, what are you using for piping ?

Q: I have a Ford Explorer 4x4 2004 model.The check engine light soon has been on for two to three weeks, I finally got it checked and they said i need my ERG valve cleaned. They quoted it for around 50 bucks, which is fine. However, i dont get paid until a week from now. Will it be alright until then?What are the effects of a dirty/faulty ERG valve if not taken care of??There are not sputtering or anything abnormal that i can tell..Thanks.: You'll be fine, drive it.

Q: I went look at a car, and the guy selling the car said that the engine valve is leaking. Is this a big deal? How urgent would it need to be fixed? How much would that cost?: Valve cover? Generally a pretty minor job. Exhaust or intake valve? Generally a pretty extensive project.

Q: Where do I get a electric valve with a 120 VAC coil: ASCO okorder is another vendor, though Grainger is good. If your budget is tight you could remove one from a dead dishwasher or washing machine.
