Q:Using a valve spring compressor
the forked end of it will go over the spring part and the solid will work on the valve ,you can only use this one if the head is off though,the smaller ones work good if the head is still on the car,the c-clamps style though is the best one to use its safer and wont allow the springs to fly off,good luck.
Q:Can the inlet and outlet of butterfly valve be reversed? Why? What will happen if the reverse gear is installed?
Our factory butterfly valve has two-way sealing, can be installed, and will not leak. If there is an arrow above the butterfly valve is one-way seal, that is, can not be installed. One way sealing will cause leakage. If you have any other questions, you can bring them up. Let me help you with that
Q:Classification of telescopic butterfly valve
(1) Central sealed butterfly valve(2) single eccentric sealed coal valve;(3) double eccentric sealed butterfly valve(4) three eccentric sealed butterfly valve (1) soft sealing butterfly valve.1) the sealing pairs are made of non-metallic soft materials, which are made of non-metallic soft materials.2) the sealing pair is made of metal hard material and is made of non-metallic soft material.(2) metal hard sealing butterfly valve. The sealing pair is made of metal hard material and is made of metal hard material. (1) forced sealing butterfly valve;1) elastic sealing butterfly valve. The pressure of the valve seat, seat, or plate is produced when the seal is closed by the pressure from the valve
Q:How big is the butterfly valve with a diameter of 80?
80 caliber butterfly valveAskIn practice, this is not the case. Why not use it when I use it?. However, I used 65 butterfly valves, right? WhyChasing the answerWhat's the thickness of your pipe?
Q:What's the difference between a clip on handle butterfly valve and a turbo butterfly valve? Where are they used?
1, the drive mode is different (handle or turbine), mainly based on the size of the valve and the opening and closing torque to decide.2. The butterfly plate of the worm valve is installed in the direction of the diameter of the pipe. In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is 0 degrees ~90 degrees between, when rotates to 90 degrees, the valve opens the card completely.3, clip type butterfly valve is to use double headed bolts to connect the valve between the two pipe flanges, flange butterfly valve is a valve with a flange, bolt with the valve flange at both ends connected to the pipe flange.
Q:The difference between butterfly valve and gate valve
Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious.
Q:What's the material of the butterfly valve seat?
Tianjin saide valve limited company can provide all kinds of valve seat material for the majority of users: white food gum X1 - X2 - X3 - Hypa EPDM rubber X4 rubber X5 - resistant rubber X6 - fluorine rubber X7 - heat resistant ethylene propylene rubber X9 silicone rubber and PTFE F4.
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:Big block, solid lifter, valve clearances?
Well, generally it's going to be .030 intake and exhaust (hot). Adjust to those clearances cold then recheck at operating temp. But it would really help to know year, make, cu. in., which aftermarket heads, to be absolutely sure. On some engines it is .024 intake / .030 exhaust and so on, depends on the lifters and valve train geometry.. What brand of lifters and cam profile? Usually they will specify valve lash and adjusting procedures. Edit: Wow, kinda' tight valve lash, krazybob, ( might be a lttle tough on the old cam lobes), and then there is your timing numbers / advice with absolutely no details to base it on ( H.E.I.?..which brand? / mechanical advance curve?, and vacuum advance numbers?, cam timing, brand of lifters, cam specs, rocker arm ratio)...Look, S-51D, the best idea is to Do- It- Right using the correct adjustment specs. The data is out there, once the configuration is identified.
Q:anti siphon valve?
as you stated, you said the directions said at least 6 from the highest sprinkler 7 will be ok as well as 20. i don't know what region you are in, but if you are in a freeze zone though it is always a good idea to blow the lines when winter comes around.
