5. FAQ

1. What is manual wafer butterfly valve?

 

Wafer style is the more common of the two and is less expensive than the lug style. The wafer style butterfly valve is just about the standard. It ís so common that no one even bothers to use the word "wafer" when ordering a butterfly valve. It is taken for granted that if a butterfly valve is ordered, a wafer style will be received.

 

2. How about the Installation of the Wafer Style Butterfly Valve?


Butterfly valves are installed by inserting the valve between two flanges using bolts or studs and nuts to hold it all together. This type of installation, of course, makes it impossible to disconnect just one side of the piping system from the valve. That benefit is received using the lug style valve.

 

3. What is the working principle of manual wafer butterfly valve?

 

A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.

Q:What type of butterfly valves do you have in DN125?
The butterfly type according to the usage, and there are many kinds of driving modes, different means, generally expressed as follows: Butterfly symbol: D; 1, drive mode: 0: 1: electromagnetic solenoid valve; hydraulic; electro hydraulic; 2: 3: 4: worm gear; spur gear 5: bevel gear;; pneumatic; 6: 7: 8: gas - Hydraulic; hydraulic; 9: Electric; handle, handwheel: no code. Connection: 2, valve is generally only two, 4: 7: flange type; clamp; 3, butterfly valve structure code: divided into sealed and non sealed type two; seal type: 0: 1: single eccentric; vertical center; 2: 3: three double eccentricity; eccentricity; 4: linkage; sealing type: 5: 6: single eccentric; vertical center; 7: 8: three double eccentricity; eccentricity; linkage mechanism: 9. 4, the sealing material: This lot, watch some kinds of H:Cr13 stainless steel; lining; J: S: X: plastic; rubber; for example: D971X: refers to the electric clamp center vertical plate rubber sealing butterfly valve.
Q:How do you draw the butterfly valve in the engineering drawing?
There is one of the most stupid way: find a picture of the butterfly valve, insert into the CAD, and then follow the trace, and there is a lot of CAD on the network of butterfly valve, yourself down..
Q:I went online to check where was the pcv valve for a 2001 ford focus, but I didn't find it. Does anyone have a picture? Thanks
The PCV (positive crankcase valve) is usually on top of the engine or in the valve cover, but it will be in different locations depending on the engine cylinder count: 4, 6, or 8 cylinder. You may have to go to a dealer and ask for a parts breakdown drawing which will show you where all the various parts are located. Some libraries have big books that show all the details about any model of car. Ask around.
Q:Butterfly valve switch direction respectively?
First, if the butterfly valve has been installed on the pipe, you can first see the mark on the handwheel. Second, there is a switch indicator on the general worm gear.
Q:Can the inlet and outlet of butterfly valve be reversed? Why? What will happen if the reverse gear is installed?
Hard seal butterfly valve in any case, the reverse loading will cause tight seal.
Q:For whatever reason, Mazda has made it next to impossible to change the PCV valve on the 929. I'm going to have to pull off the plenum and the passenger's side valve cover to replace a $2.00 PCV valve. Before I get too involved, I need to know the torque specs for the valve cover. Also, any other tips on this process would be greatly appreciated. Can I reuse the old valve cover gasket if it's still in good shape? Should I use any kind of sealant in addition to the gasket when I put it all back together? Thanks in advance, by looking at this motor, I can tell I'll have my work cut out for me (for a friggin $2.00 PCV valve, it's usually SO simple!). Like I said, any and all help is greatly appreciated.
you do not torque valve covers down, buy a new gasket , I would get a good quality rubber one and some blue rtv sealer, clean any crap off the valve cover no glue no bits of gasket nothing, same thing on the head surface, glue the gasket on the valve cover, let it set, then carefully put it on, start with the bolts in the middle and work out finger tight all of them, then just snug the bolts down, dont crush the gasket, you can also use a light duty locktite to hold them in place, and often times old valve covers are warped, it is too your advantage to make sure its as flat as you can get it, or spend a few bucks a buy a new one. your choice, but snug the nuts down good with out crushing and bending the thin sheet metal of the valve cover.
Q:Not the cold and hot water shut off valves. The one with a tiny handle and it looks like a T. what does it do? should I mess with it?
Well definitely should not mess with it, especially if you do not know exactly what it is and more important what it controls. If not water, then it could possibly be the shut off for a near by gas appliance. It would help if you described the size and color of the pipe. Maybe you could try to trace it , where does it come from and where does it go to ?
Q:How much is the Honeywell butterfly DN300?
Find the agent or find a reliable valve plant a lot of foreign brands are in Chinese OEM so find a reliable factory is relatively good service to keep up
Q:Ok, so I took my car in for maintenance (Mustang GT convertible 2002) and the mechanic told me the valve gaskets needed to be replaced and when he gave me the estimate, they were two seperate charges for valve gaskets and valve covers, total of about $250.00 not including labor. Is he trying to rip me off cause I'm a girl by the way? Anyways, I didn't get it done cause it needed something else too and I didn't have enough money so I said I would be back in two weeks. So I called the dealership to inquire about the price and I asked the parts guy for a price on valve gaskets and he was like, I don't know what you mean, we have valve cover gaskets but nothing says just valve gaskets? I told him to give me the price anyways, thinking I would ask my brother (who hasn't tried to help me anyways) and it was $60.00 for both (I need two). How can this be if the other guy was charging me $250.00 for different parts? Help!!! Frustrated and confused, I don't know anything about cars :(
LOL. No. You don't get away that easily. The valve cover gasket only keeps oil from splashing all over the engine bay. It literally covers the valves, sealing the engine interior away from the general environment. Th head is the part of the engine that the valve cover sits on. It contains the valves, and either the camshaft or the rods that lead to a camshaft deeper in the engine, and of course the rocker assembly. You have to remove all those big bolts along the casting to break the head free, and you'll need a torque wrench to get the pressure right when you're reinstalling it. The head gasket seals the tops of the cylinders [incorporated in the bottom of the head] to the cylinders themselves [bored into the block proper.] Have fun!!!!!
Q:does it come in when you go over a certain rpm or do the valves change depending on how far you depress the throtle?
The variable is the valve timing. The spark plug fires a split second before the piston reaches the top of the stroke, to give the fuel a bit of time to burn. But, the faster the piston travels in the bore, that split second gets shorter shorter. So the engine computer changes when the spark plug fires when the valves close, to maximize the power from each ignition stroke.
