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

♦ 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: My 91 GMC Van has an Idle Control Valve that is unplugged, but the van still runs great. Will the valve being unplugged, result in harm to my vehicle?
- Won't hurt a thing.
- Q: I have a 1989 Jeep Cherokee with 218,700 miles on it and my engine has thick oily gunk on it, possibly from a leaky valve cover gasket, should I change the gasket? I have been told that this is normal and not to worry about, but from the amount of this gunk, I find it hard to believe this is normal. The top of the valve cover has a light covering of gunk, but on the sides and towards the bottom of the engine. it gets very thick and at some places you can't even make out whats suppose there. Does a leaky valve cover gasket mean that there is another problem going on?Can leaving the oily gunk on the engine cause any problems?Any info would be greatly appreciated.
- Valve cover gasket start leaking over time. That is normal. The thick oily gunk is from years of engine neglect. It doesn't happen over night. It's a good idea to clean the engine once in a while. As for the valve cover gaskets, they should be replaced (should have long ago) to prevent any more oily gunk from building up.
- Q: Where are the valves. And how do I fix it? Will I have to buy anything? I have a 98 Honda fourtrax 300.
- Valves make a ticking noise due to: -normal wear -faulty lifter -faulty valve spring
- Q: I have a honda civic and i took it to get an oil change and they told me that i had an oil leak because my valve cover needed replacing. I did not let them do the work. I called my personal mechanic and he's out of commission for a little while, so he referred me to a friend of his. He said he cleaned all of the built up oil and replaced the valve cover. I noticed yesterday that my car looks like it is leaking oil really bad. I'm wondering, could this be from him washing the old oil that was leaking? My belts seem to be squeaking, like they do when it rains. Any ideas? could this just be excess water that he cleaned it out with?
- To determine If the valve cover-gasket is leaking again, take the car to a wand-type car wash. Shut the motor off, open the hood and thoroughly wash the engine and compartment down with hot water and soap. Concentrate on the valve cover itself and the mating surface between the valve cover and cylinder head. Rinse with hot water spray. This is the only way to clean-up the previous mess so everything will be dry and clean. Use a flash-light if you have one to inspect all the way around the lip of the valve cover to look for any bright, shiny oil that could be leaking again after a short drive. Having been cleaning engine compartments for 45 years at car washes, don't worry about electrical connections, cracking or breaking anything. There are quite a few tricks to make valve covers seal properly. To start with the cylinder head has to be clean and dry, the valve cover had to be clean, *flat and dry and use only premium Felpro, silicone impregnated valve cover gaskets.
- Q: I really like the sound that a blow-off valve makes when they are in audi tts. So I was wondering if I got one for my '02 225hp Audi tt if it would damage the engine in any way. I have read that diverter valves are better, but I want the sound of the blow-off valve. Also any recommendations on blow-off/diverter valves would be great.
- Well, in the audi system it expects to get the extra boost back from the diverter valve so it would be against your best interest to blow off all the boost. However, they do make blow off valves that sound great but only lose 10-30% of the boost which would have little to no effect on the car and you still get that cool sound. I personally am not into blow off valves so I've never bought one but I've heard some good things about Forge blow off valves and I believe they make a 30% blow off like what you would want.
- Q: I am wondering if i can put a blow off Valve on my Crossfire and still get the same sound as if it had a turbo. the car is stock and i just got it so i do not know if it does have a turbo already. Can anyone help me with this.
- It does actually no longer something stable on your motor vehicle except you push 20 lbs of advance. it is going to truly make you run wealthy between shifts and could additionally provide you idle issues. our first improvements could be suspension. the vehicle handles properly inventory so getting better it will make the vehicle fell extraordinary. i'm assuming you're new to turbocharged automobiles so i might advise analyzing up on sites like I-club or NASIOC and learn as much as you may in the previous you initiate enhancing and blow your motor. It happens each and all the time so i'm no longer exaggerating.
- Q: 1990 Pontiac Sunbird 2.0L Fuel Injected has EGR Valve, I can suck and blow through the hose connected to it, an I supposed to be able to do this, or not...? It looks old, like it's been on the car forever...
- You can do a simple test of the valve - take a clean hose into the input - suck on it and place your tongue against the hose - it should hold vacuum and your tongue for about a minute. If it doesn't, replace the valve. They can also get clogged with deposits that can cause problems. For one that old, you may do well to just replace it.
- Q: First off I'm a girl. :) My 2.0 non turbo engine has a bent valve. I have been asked to pick up the valve. But I need to know if its for the intake or the exhaust. I know the guy how is going to fix it said he will have to sand down the cylender that it goes in it. The car sounds like it knocking when driving or sitting still. The guy who is going to fix it is at work right now and I'm suppose to order this part right now. Is it an intake or an exhaust valve?
- tell him that you dont sand down the seat.if he does,then he could get it so it wont seat right.he needs to lap the seat.now 1 of the valves are smaller then the other.if it backfires through the exhaust then its the exhaust valve.if he know how to do it,then all he has to do is take a piece of paper and hold it up to the tailpipe and see if it sucks the paper in.
- Q: Sohc ZC (d15) honda I'm going to be painting my valve cover am I going to need new seals? What do I need to take it off and put it back on ? Please help I have the high temp sand paper all ready to go I just want to be ready
- if i were you i would replace the gasket ! even if it don,t break taking it off it,s best to put a new gasket on when you pull the valve pan !
- Q: Hi everybody,I need some information about the operation of a double solenoid valve and how to control it using a PLC
- A double solenoid has two solenoids, and when voltage is supplied to one (and not the other) the valve shifts. Note that if voltage is supplied to both solenoids at the same time, the valve will stay in the position is was in (i.e. it won't shift since the solenoids will be working against each other). This is typically not desired, so make sure you remove voltage from one side when supplying it to the other. If no voltage is supplied to either solenoid, the result will be the same as if voltage is supplied to both, in that the valve will stay in the position is was in. What this means is that the cylinder has no home position, so when power is cut, the valve will stay where it was at that time, and the cylinder will continue to do work in the direction is was working in. Again, depending upon what the cylinder was doing, this may or may not be desired. For Conrolling with PLC you may need to wire two discrete outputs of PLC to those two solenoids using relay. And the ON/OFF those two outputs as required.
