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

♦ 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: I have a 1997 Toyota Corolla. My check engine light has been on. I tried to get my car smogged and it failed. I then got an oil/air filter change and just yesterday I replaced the EGR valve which was the result given after 2 diagnostic tests. The mechanic gave me my car and the check engine light was off, I've only driven about 5miles and the light is back on. I have to pass smog asap to register my vehicle. I plan on calling the mechanic back and telling him the light is on, but could it just be a sensor?
- Let's start from the top. Your check engine light has been on and you took it to be smogged and you probably didn't know that the check engine light on is an automatic fail. So you get the oil/air filter changed without a reason, just because. Next, the diagnostic tests point to the EGR valve so you have a mechanic replace it, that is instead of having the mechanic figure out the real problem The mechanic could have replaced the valve or not, but you didn't get the old one from him, so you don't know if it's been replaced. He disconnected the battery so the light went out. Now it's back on so the problem isn't fixed. Could it be a sensor. Well, sure, but proper testing would tell you if it was. My GUESS is the EGR valve and ports where the EGR attaches just need to be cleaned out but without proper testing, that is just a guess. My suggestion is find a different mechanic, one who doesn't just disconnect the battery to turn the check engine light off, and don't go in telling this new mechanic what you think the problem is because you don't know.
- Q: ok, after lots of exploring around online and from some great answers from this site I have found the problem to my explorer. The torque converter solenoid mounting clip broke. thats it!! new question, do i have to take off the valve body to remove the solenoid. If so any tips? its way new territory for me. I hate automatics!!
- What are you? 9 years?
- Q: where is the oil pressure relief valve at in a 2003 ford focus
- its in oil pump some engines have a oil filter relief valve in behind the oil filter that can cause this problem but not certain if your engine does but worth a check
- Q: Is it supposed to go on or only in cases when the power goes out??? I bought this pump and the directions are horrible!!! There isn't room for both the air stone and the check valve!! How does this stupid thing work???

- Q: when heater heats water there is a small leak thru the releif valve. need answrers to possible reasons for malfuntion. leak is not continous.
- SHUT OFF WATER AND REPLACE RELIEF VALVE, IF YOU HAVE HARD WATER IT CAN ACCUMULATE LIME AND FORCE VALVE TO OPEN. ALSO HEATING ELEMENT MIGHT BE BAD AND WATER HEATER IS OVER HEATING. VALVE SHOULD RANGE FROM 150 TO 210 PSI NOT 30 PSI.
- Q: This happens when the sprinklers are ON and goes on for a minute after the sprinklers go off. Should I replace the whole valve or do I need to check the diaphram or solenoid head? In addition to leaking, I have noticed a more potential problem - water hammer. As soon as the sprinkler goes off, I hear this loud banging noise from the pipes underground. Water pressure is fine ~ 50. My guess is air inside the pipes is causing this. Is this because of faulty valve which is leaking?Also, any difference between the valves that are sold in Lowe's and Home Depot to that of commercial valve? My lawn guy says commercial valves last a long time.
- The water hammer is due to the sudden closure of the control valve. They don't turn off slowly. The sudden shutoff of the valve causes the inertia of the water to slam against the end of the sprinkler pipe. You can device from a well stocked hardware store to place in you water line to reduce or eliminate the hammer. As for the leaking problem, I disassembled the control valve and found the diaphragm out of position. On mine, there is a very, very small key on the diaphragm that aligns it with the case. Also check for debris in the solenoid valve seat and anywhere else in the valve. I can't address commercial vs residential valves other than if the valves are brass, they are more durable.
- Q: in confederacy of dunces when ignatius talks about his valve closing all the time. is he talking about a throat valve or his he talking about like some intestinal valve? my mom says it's his intestinal valve, but i think he's got asthma or something and he's talking about his throat
- Suffering the trauma of the downward cycle, Ignatius confines himself to his bedroom, where he chronicles his version of history on tablets of Big Chief paper. Further, the stress of these incidents is manifesting itself physically. They have caused his pyloric valve to close--an ailment he suffers anytime he is subjected to anxiety and stress. With his valve sealed shut, gas fills his stomach, and he becomes severely bloated. In an attempt to pry his valve open, Ignatius lays on his stomach and begins bounhing up and down on his bed. Though it does not open the valve, the bouncing does cause a small erection, to which Ignatius decides to tend. Visualizing his childhood dog, Rex, he brings himself to climax.
- 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??
- The seal may be worn. Call back the company that installed the pump...
- Q: my dad is going to go under heart valve replacement what are the chances of him surviving he is 58 years old and has copd
- It depends a lot on which valve and why it's being replaced, but unless the COPD is very bad, the average chance that a 58yo man who does not have any other major medical problems will survive single-valve replacement surgery is better than 98% if the surgery is done by an experienced surgeon at a good hospital. The COPD will very likely mean that his post-operative recovery will be prolonged and difficult, but he should do fine.
- Q: In December I got a new John Packers Bb Cornet and it was fine to start with. But recently the valves have been sticking, especially the 1st and 2nd ones. Even when I put valve oil on them they stick. It's really starting to annoy me, is there any else I can do to prevent this?
- If the valves continue to stick after being oiled, then it's time to clean your horn. Remove all the valves (making sure to keep them in order so you don't put them back in the wrong casings) as well as the slides. Fill a sink with warm (not hot) water with liquid dish soap. Wash all the parts gently with a soft clean cloth. There are special brushes available at music stores for cleaning the insides of slides. After cleaning, pat everything dry, apply fresh grease and oil, and reassemble.
