- Q: What is the International Standard or other acceptable calculation or table for determine the air supply of pneumatic actuator in shutdown valve 6 to 24.Desired answer will be air flow in SCFM.Thank you.
- Shut down valves I've worked with haven't had an 'Air Flow' for their operation. For the smaller valves, they consist of diaphragm operated valves either held open or closed by pneumatic pressure. The air supply at 25psi to give a diaphragm holding pressure of 15 psi, is via a solenoid valve which dumps the air pressure to either open or close the valve depending upon its function. (That of isolating a system or relieving pressure). The solenoid is actuated by a signal from the shut-down system, and the valve is a 3-way unit which isolates the supply air and vents the pressure off the diaphragm. Other SDV's in my experience, are operated in a similar way but are much larger and are operated by a pneumatic air cylinder and piston with air supplied at 100 psi. Others encountered are ... MOV's...Motor Operated Valves that can be automatically operated from the shutdown system, or Operated Remotely from a safe distance (ROV's).
- Q: Hi i have a 00 bmw 320d and am trying to find out information on puting a dump valve in, is it possible?, what type of dump valve? and how hard it would be to put in?? any help would be much appreciated.....Thanks!!
- Most diesels do not have throttle valves (including yours), therefore a blow off valve would never work. They work by relieving the pressure build up caused when the throttle valve is closed (foot lifted off gas pedal in a petrol engine), which happens when you shift (usually only for manuals) so the built up pressure does not bring the turbo speed down. A side effect of this pressure being dumped is the whoosh sound, which some people desire more than the performance gains it offers. That sound is the air rushing out of the intake system, which usually has been metered already, and now is wasted. The ECU measures that air and adds fuel for it. When it gets blown to atmosphere, the fuel is added, but not the air. Now the engine is running rich. There are some systems that recirc that air back to the turbo, but then there is no whoosh sound. Anyway, since most diesels do not even have a throttle valve, it won't do any good.
- Q: is it possible to check valve to piston clearance with out taking the heads off? I want to buy a bigger camshaft for my 351 windsor stock pistons with 1970 heads. cam is 230 duration (280) and 512 lift
- No you can't check the valve to piston clearance without taking the heads off. I had a 289 bored out to 351 and ran stock 351 pistons. So your stock pistons should work with the new camshaft. I know I'm a girl but my husbands a mechanic and for fun we rebuild muscle cars.
- Q: if safe, at what age should a woman with mitral valve prolapse be pregnant?
- My mother has it and she had two children, one at 22 and one (me!) at 24.
- Q: Ok guys I have a 70 4 bolt main 350 40 over. I have a lunati 292 cam 230 at 50 degrees. 480 lift. The kit says 1.5 rocker ratio. No valve adjustments needed. I just boight edelbrock aluminum heads summit number 5089 64 cc with 185 intake runner . And comp cam roller tip rockers. That say 1.52 ratio. All my decks on the engine and heads are stock not shaven. I have speed pro pistons with .125 dome. Im using standard felpro gaskets. Ok my question is will standard lenght pushrods work for this build. They are 7.794 length. And will my piston head clearance be ok cause of my domed pistons. and do I need to find rockers that just say 1.5 ratio to make this work or are 1.52 the same. Thanks
- Your fine with the roller tip 1.52's
- Q: pls. tell me the differnce between isolation and block valves and also where it to be used .
- An okorder /. There's numerous systems that use isolation valves. Let's say you want to make some ice cream, you open the isolation valve to let the milk flow into the mixer, then open the valve to let in the cream. Depending on the valve type, you could then open it to allow in the vanilla, sugar, egg, etc. All with the same valve. It just keeps the ingredients from coming in contact . A block valve is used to shut off a supply, so you can perform maintenance, or just stop the flow.
- Q: I have a shut off valve under the sink that leaks when you try to turn it OFF. Why is that?I need to fix faucet leak as well. do i need to shut water off to fix faucet? Need to fix valve first. Cant figure out why valve leaks when turning off.
- when a valve is left open for a long time all is well until you move the stem quit common with 2 wrenches hold the body of the valve with one and with the other tighten up the bonnet packing nut where the water is coming from just a little twist should do it 1/8 to a 1/4 turn .what this will do is smash the bonnet washer a little tighter to the valve stem shaft. gl
- 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.
- The term is E G R Valve. Stands for Exhaust Gas Recirculation Valve. This valve Recirculates exhaust fumes back into the intake of the engine to burn the fumes 2 times.
- Q: The water shut off valve that is under my sink in the bathroom is leaking and I need to replace it. I am wondering if I need soder the new one or can I just put some thread tape around it.
- More ofter than not the innards of a valve will deteriorate and start to leak, when that happens its best to replace the valve. Since you ask about soldering the shut off valve, I'm going to assume that you have a copper line coming out of the wall. Older valves required soldering, nowadays there is a compression fitting that eliminates the need for soldering. Once you have the correct size of the pipe turn off the main water supply. Remove the old valve (may need to take a hacksaw or tubing cutter, if its soldered on). Then slip the new nut and compression ring over the pipe. Next bring the valve up to the pipe and tighten the nut to the valve. Once the valve is secured on attach your lines, preferably new replaced lines. Open the valve line, and then turn on the main water line and check for leaks.
- Q: i have a 1991 rm125 and i want to open the power valves myself can anyone tell me how to do thisTHANKS!
- dude leave the power valves alone. you do not know what you are doing.
