- Q:How to connect the signal butterfly valve?
- The signal butterfly valve should be the surveillance and alarm of human action. Once it is closed, it will alarm the system.Signal butterfly valve wiring method:1, open the switch box cover, according to the electrical control requirements, the cable core line to the corresponding terminal, and sealed cable imports, while the cable fixed, to prevent external force damage when the cable wiring.2, when the valve in the "closed" position, the clockwise rotation of the following relationship to the cam is just touch micro switch cam (you can hear the clicking sound), and then tighten the screw on the cam cam.3, when the valve in the "fully open" position, counterclockwise turn the upper open cam, with the same method to adjust the open cam.4, adjust the limit screw, when the valve in the "full off" or "open" position, should not make the limit screw just at the top of the worm gear limit plane, and should have a certain gap, and then tighten the lock nut on the screw.5, on the cover of the electrical switch box cover, when the valve in the "off" position, the pointer opening indicator to dial "0" scale, and tighten the screws pointer.
- Q:What is the difference between wafer (flangeless) type and LUG type of butterfly valves?
- WAFER butterfly valve is the valve is divided into LUG (ears) with and without LUG, ordinary LUG without clip on 12 points in the direction of valve is generally two to four bolt holes was not, whereas the LUG of butterfly valve cross dispersed in a circle. Bolt hole. With LUG all bolted through the LUG, so that the butterfly valve and the clamp on the two flange connection is more solid, you check the valve picture, it is easy to understand
- Q:Specifically an engine valve retainer.
- TRhe retainer and locks works together to hold valve to spring and keep valve from falling into the cylinder and spring from coming off the top. The locks are tappered, small end at bottom, big end at top. You compress the spring down, drop retainer over valve, put locks in groove of valve stem and pull up on the retainer to lock the retainer and locks in place, the relese the pressure off your spring compressor and the valve spring now holds pressure up on retainer which forces up on the big end of locks and holds everything together
- Q:Butterfly valve D71X-16 and D71X-16Q what is the difference?
- The two difference is that the body of the material is not the same, 16 behind with no sign, expressed as a default, is carbon steel (usually C), if you need to specify material, just behind with symbols, such as Q nodular cast iron, stainless steel P.
- Q:I HAVE A 2003 FORD EXPEDTION THAT IS IDLE ROUGH,AND WILL EVENTUALLY STALL. TODAY I FOLLOWED THE PCV VALVE HOSE TO THE BACK OF THE THROTTLE BODY AND NOTICED THERE IS A BIG HOLE ON THE ELBOW OF THE HOSE. HOW CAN I CHANGE IT? CAN I JUST FORCE THE HOSE OUT AND SIMPLY PUT A NEW ONE? BEEN HAVING THIS ROUGH IDLE /STALL PROBLEM FOR A WHILE I CLEANED IAC VALVE, THROTTLE BODY CHANGED THE AIR FILTER AND ALSO CLEANED THE MASS AIR FLOW SENSOR, I HAVE A P0171 system to lean(bank 1) code
- So, the rubber elbow hose has a hole in it. Your best bet is to get the replacement from the Ford dealer. Yes, you can buy just the elbow part from the parts counter at the dealer. If they start acting all dumb (and won't help you or sell you the part) then, go to a different dealer for the part. Another thing you could try is a used one from the junk yard BUT, it's been my experience that the rubber gets too hard and the PCV valve needs a lot of encouragement to be removed. Sometimes you'll damage the used elbow by trying to get it off of the engine or removing the old PCV valve to put in your replacement valve. That's why I recommend getting a new one straight from the source. They are pretty simple to change with ordinary hand tools and some mechanical know-how. You just pull the elbow off of the port that it's attached to on the engine. The valve will probably have a steel clip that goes around the hose at one end of the valve inside of the hose. You simply squeeze the clip with a pair of pliers and tug at the valve until it comes out of the elbow.

- Q:1988 volkswagon cabriolet, rabbit tried mystery oil let sit for a week having trouble with stuck valves even taken a wrenrch to manually unstick. help any suggestions 4 cyclinder car has been sitting up for about 4 years
- The only reason for a stuck valve is if it bent from a thrown timing belt. Sitting 4 years will not cause valves to stick usually, because there is always some oil leakage from the head, that prevents rust. How do you know the valve is stuck? Have you done a compression test, checked the valve clearance? When you say you take a wrench to manually unstick it, it would help to know what you mean, because there is no place to put a wrench that would help unstick a valve that was stuck. You need to tell us much more.
- Q:How can one - way sealed butterfly valves and two-way sealed butterfly valves be distinguished?
- Two way hard sealing butterfly valve:Two way butterfly valve on the valve body usually does not indicate the direction of the media arrow sign, in the design of two-way sealing butterfly valve stem force is greater than one-way butterfly valve stem. The same diameter, pressure butterfly valve, two-way sealing butterfly valve rod diameter than one-way sealing butterfly valve stem diameter. At the time of installation, the butterfly plate can face or back the direction of the medium, without considering the flow direction of the medium.
- Q:Do you use the straight stem butterfly valve in the fire fighting engineering?
- Bar valve bar, did not hear the bar with butterfly valve, ah, there are pairs of folder and hand wheel type bar
- Q:I have 1993 Seville 4.9. I got a new EGR valve but it didn't help. I tested it with vacuum pump, it won't hold pressure at all, same with old one. Is that new EGR valve bad or just different type of EGR that vacuum pump won't work? Thanks!
- The first source, pages 20-22, lists all 9 basic types of EGR valves. Not all the types are vacuum operated, but check out #5 and #6 - they behave very differently from each other without a real live exhaust system connected to them.
