Q:Im replacing the valve stem seals from my 1991 jaguar xj6 and the valve dropped?
As you've been asking this question for a week now time and time again I guess its time for the Nasty one to set you straight, As I've been a mechanic for over 30 years my knowledge is vast and no further questions need to be asked, You screwed up! now that you have dropped the valves into the cylinders you have to remove the head or heads that you screwed up on, period, end of sentence, there is no other way, and no you will not need to remove the engine to remove the heads, But had you did a bit of research before diving into this without a clue you would have found that a simple length of clothes line or thin rope stuffed down the spark plug hole and turned the engine over by hand to bring the piston up and push the rope into the valves to hold them place would have saved you from pulling the heads off this POS, excuse me I meant fine piece of English engineering, by trying to turn the engine over now is just a good way to bend a valve, and for all you know the piston could have been at the bottom of its stroke and the valves fell out of there guides are not even in contact with the head, so with this said do some research on how to remove the heads on this thing and fix your screw up. Live and learn, you just opted to learn the hard way,
Q:What is the medium flow rate when the centerline butterfly valve is fully open?

Q:unstick valves in 1988 volkswagon rabbit?
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:What does "D41X-16" mean?
There are many kinds of valves, so each valve has a specific model. Butterfly valve D41X-16 code D refers to the butterfly valve, 4 refers to the connection form is flange, 1 refers to the drive mode is manual, X is the valve sealing ring material is rubber, 16 refers to pressure, 16 kg. Valve model is composed of seven elements: valve type, connection form, drive mode, structure, sealing ring material, nominal pressure, material. You can ask me if you don't understand. Dual valve []
Q:Is the pressure test of the centerline butterfly valve checked or checked?
Every factory factory must require pressure tests.
Q:Butterfly D371X5-16ZB1 what does each letter stand for?
Daily valve pressThe regular model is out of step with you. I can only explain the regularD371X5-16ZB1D is butterfly valve3 is the turbine drive7 is the clamp connection1 is the display opening signX is a rubber seal16 is 16 kg pressureI don't know the other superfluous letters
Q:Butterfly valve in use when should pay attention to what problems?
After the last in the pneumatic butterfly valve after use, also need to be cleaned immediately after the valve is closed, should use soft cloth to clean the valve, which may have some impurities, dirt removal, and oil lubrication, so it can better guarantee the use of the next.
Q:What's the difference between butterfly valves and check valves?
Butterfly valve is manual, only switch function.The check valve is an automatic valve, which prevents backflow of the pipe medium.
Q:How can I get the fire signal butterfly valve?
At the input end of the input module, some resistors or terminals are added to the product
Q:anti siphon valve?
anti siphon valves are junk. just install regular valves and put in a backflow preventer on your mainline before all the valves, but right after the shut off vavles.
