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

- Q:im trying to turn on my sprinklers from the valve manually,but doesn't seem to work, the valve it's an antisiphon rainbird valve with two little knobs, I know that one is the bleeder and the other the pressure control, or something like that, and the solenoid has the on and off arrows on it, but i can't do it anyways,they come on automatically right on time ,it's just the manual thing that i can't do, please help me,i really need it

- Q:I have a 2004 rmz 250 i was wondering if i could get some specific details on how to adjust and the spec's for the intake valves... thanks
- Buy a manual for your bike. The question is far too broad to be answered here due to the complex nature of a modern valve train, like found on your RMZ. It involves removing the intake and exhaust camshafts to gain access to the shims underneath the buckets on top of the valves. You must know where to time the cams again in relation to the crank otherwise, it is very possible to destroy your engine if not installed properly...Hence the advice on obtaining a quality service manual beforehand... It's also why the shops charge a seemingly extortionate amount.
- Q:I just fixed a clog in my bathroom sink by taking off the p-trap. I had turned off the water valve beforehand, and when I was done I turned it back on. After this, all that came out of the faucet was a trickle. Turning the valve in the off position does not stop the trickle. When I first turned the valve off before taking off the pipe, the valve was not turned all the way left or right. It was in the middle, but the water flowed fine. When I turned the valve all the way to the right, the water shut off at the faucet. My apartment is pretty old. Is this valve most likely broken?
- if your water valve has a plastic handle it is probably striped. take the handle off and try using pliers to turn the valve this will tell you what you need to know.
- Q:What would this envole, can i size up/down the port on the existing valve with just changing the mechanical componts.

- 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.
- I have been given the equivalent line from our water application whilst the stress valve broke and blew up our water softener it rather is the 1st element on the line from their tension regulator. luckily, it has a life-time insurance yet their plumber instructed me that it extremely was once the accountability city on the grounds that of the stress regulator which they admitted to being at fault whilst they replaced it.
- Q:here's some additional info asking of my question...I plan on buy a BLOWOFF VALVE and woundering where does the BLOWOFF VALVE goes in my car or do i have to replace with stock EGR VALVE using same hoses or help me please don't wanna screw this one up
- Ben- If your car is not turbocharged you cannot install a blow-off valve. If your car is turbo-charged, this annoying device replaces the Waste Gate. What does a blow-off valve do for your car? NOTHING! It does not add horsepower. It is simply a noise maker to attract the attention of Law Enforcement. So what can you install to improve a Turbo-Charger's boost capability? HKS Controller, Cold Air Intake, Intercooler, High Flow Catalytic Converter, and some type of high performance exhaust system. What's this going to cost? $5000.00+ easy! Lastly, the Blow-Off Valve has nothing to do with the EGR Valve. Two totally different devices, performing two completely different tasks. And... not to burst your bubble. Since you don't know the difference between a Blow-Off Valve and an EGR Valve, I suggest you start taking some basic Automotive Technology classes BEFORE you get into learning about the high performance parts. Why? The last thing you want to do is get into something that is over your head, then have a very large repair bill on your hands because your inexperience in the task at hand is the result of the damage done to your car. One last item here. Performance does not equal fuel efficiency. The more horsepower you want, the more fuel will be required to make it. The more horsepower you desire, the lower the reliability. This becomes a factor because you will be harder on the parts which are doing the jobs required of them. So think before you decide to make major changes to your daily driver. Making performance changes to your daily driver, is a great way to have your friends passing you up with you stuck on the side of the road facing a big tow bill and an even larger repair bill. Bottom line, build your muscle car for a weekend romp, and leave the 4 Cylinder job shuttle alone. Just speaking from 25+ years of turning wrenches!
- Q:Is there a difference between the atrioventricular valves in the right side versus the left side of the heart?Is there a different between the pulmonary valves?
- Nope - the atrioventricular valves always seperate the atrium and ventricle, and the pulmonary valves, at both exits to the heart, will always stop backflow into the ventricles. They maintain similar functions on both sides of the heart.
- Q:Hello, I went to my garage last friday because my exhaust emmisions light was on, on my Bora MK4 2003 52 plate 1.6 16V. They said its a faulty EGR valve which could be from being clogged up with sh*t. But they said it would be fine to drive, and that the rough idle wouldn't harm the car, and to unplug it if the rough idle became annoying. Its now sunday 3 days since the garage diagnosed it I drove about 250 miles over these days. With the exhaust emissions light coming on then sometimes going off. I think the EGR Valve keeps sticking closed and the engine is very hard to start. Is there anything I can do to help start the car? which is better having it plugged in or unplugged? how do you take the EGR Valve out and clean it what tools are needed is it complicated. any ideas on how I can help it start ? I've tried unplugging it, it makes no difference really.
- The EGR valve or Exhaust gas Recirculation valve is placed on the exhaust gadget. those frequently get hung up with rust and different exhaust deposits. The motorcar might want to be less than production unit assure being in easy words 3 years old. i might want to examine with a broking service to work out if the motorcar and/or section continues to be less than assure. A defective EGR valve will reason the computing device to make the incorrect settings to the gas and air mix causing the engine to run too prosperous or too lean. Its no longer too unfavourable contained in the little while period, yet your gas mielage will struggle through, and also you are able to fail a state inspection so get it repaired previously then.
- 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?
- When valves are turned all the way in an open position they tend to get stuck. Try a heat gun but make sure you have a copper line feeding into the toilet tank, not a plastic one because it can melt. Just heat the valve for a few minutes at a time, because over heating it can damage the rubber washer inside the valve. If all fails then it has to be replaced by someone who is knowledgeable.
- Q:HI ever one i have a 1969 1500 beetle engine i have just but 1600 piston and barrows on it but when i but the rockers on i have no valve gap at all. ive wound out the adjusters all the way and i still can not get a feeler gauge between the rocker and the valve. Please help cheers Adam
- The problem could be that the crank shaft has not been turned to the place to adjust the valves. The push rods could be the wrong length ones too.
