Q:The difference between butterfly valve d71x_10s and d341s-10

Before distinguishing between the two, you must first read the identification of the valve type:D stands for butterfly valves,3 means that the worm gear is connected and the drive does not indicate the handle7 and 4 indicate pipe to clamp connection, pipe flange connection, respectively1 means single eccentric, that is, the stem is not in the center of the butterfly plateThe former S indicates the material name of the valve body - plastic, X means sealing and the lining material is rubberThe latter S indicates the sealing lining material code ---- plastic, and the valve body is cast iron.10 means stress.

Q:I did a compression check on my 350 chevy. I have low compression of 175psi on one cylinder.The other seven cylinders range from 195psi to 205psi Could the valves be too tight on the cylinder with 175 psi compression?

unless they have been tampered with that wouldn't be it,they usually wont tighten up on their own,i would suspect maybe a valve with a slight burn place on it that's causing that to happen or a ring causing you to loose that much compression,try adding a small amount of oil in the cylinder and then do the compression test again,that will tell you if its a ring or a valve,that's a big loss of compression ,and when you see that much of drop its usually a burnt valve.good luck.

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

just undo the clamps, and pull. it may need some wiggling and tugging, as its been on there for 9 years now without moving. put on your new hose, and replace the clamps, and youre done. next time, try not using all caps. it doesnt make us want to answer your question anymore just because its in caps, in fact, maybe a little less.

Q:What does the butterfly valve model d344h, d345h, d346h, d347h mean?

According to the international standard of the letters and numbers apart to explain D344H D is a unit of butterfly valve, two unit 3 is driving mode: turbine, three unit 4 connection: flange connection, four unit 4 Structure: seal type linkage, five unit H sealing material: Cr13 stainless steelD345H compare yourself to the above. Unit 5 four is a sealed, single eccentric structureD346H four unit 6 is an unsealed center vertical plateD347H four unit 7 is unsealed double eccentricIn general, there is only one difference between them: the structural form is different!

Q:Butterfly valve in use when should pay attention to what problems?

Q:Hey YA! I am looking at getting an 01 Honda Prelude this month and valve adjustment keeps coming up when people discuss this car and other cars as well. What is this? Does it cost a lot to do, and is it important? Thank you!

Some cars have little hydraulic gizmos to keep the valves more or less where they're supposed to be. Doing without them is, according to some, a tad more precise, but you have to have the valves checked now and then. (On my old Celica, it was a 60k maintenance item.) It will probably run a hair better afterwards.

Q:i just finished installing a sprinkler line for my lawn and i used anti siphon valves and 4quot; sprinkler heads. it says in the manual that it has to be at least 6quot; from the highest sprinkler. i think i made a mistake. i installed it 7quot; from the highest 'sprinkler line' . will i have a problem with that regarding the operation of the anti siphon valves and the sprinkler system itself?

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.
