- Q:Butterfly valve network and ordinary butterfly what is the difference?

- Q:Butterfly valve structure and working principle
- Butterfly valve structure: Center to clip butterfly valve, single eccentric butterfly valve, double eccentric butterfly valve, three eccentric butterfly valve
- 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: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.

- Q:Which is better, the round two lobe butterfly valve?
- The company has advanced sheet metal CNC processing line, strong technical force and strong production capacity. At present, the main products are: air outlet, air valve, muffler, fire damper, static pressure box, wind box, etc.. Especially round type double butterfly butterfly valve has obvious advantages.
- Q:I need a valve cover gasket replacement because mine is leaking a tremendous amount of oil. The mechanic says it will cost about $269.00 plus tax. I wanted to make sure this figure was the average since I do not know a lot about cars. My car is a Mitsubishi Diamante 2001.
- The gasket set is probably $ 20, so double that to $ 40..... 270 - 40 is 230, divided by 2 man-hours, which is the usually dealership minimum, gives $ 115 an hour. I DON'T THINK SO !!!! Unless you live in Hawaii where everything is expensive, that sounds steep.... real steep. Dealers around here get like $ 85 an hour, so two hours is 170, plus 40 is 210 bucks; Still killer money for the dealer..... I'd question that estimate ask if there is some extraordinary challenge to working on your car. It is possible there are accessories mounted over the valve cover that will have to be moved, or that's it's a canted V-6 with one valve cover tucked up against the fire wall. Be nice, smile, ask questions.... Maybe even have someone show you what has to be moved on your engine to get at the valve cover(s). If you're going to pay that much $$$, you should learn something, also.

- Q:what are the step i need to do so i can change the valve seals my truck has been smoky.,,, any websites i want todo it myself... 1989 chevy silverado 2500 350 engine 5.7L
- First find out if that is the issue. Do a wet/dry compression on all the cylinders. That is where you do a compression test on all the cylinders and write them down. Then squirt about three pumps of oil from a oil can into each cylinder and retake the compressions. If the compressions don't change and are low, the valves are burnt and you need a valve job. If the compressions go way up after the oil seals the rings, then the piston rings are bad and the engine needs rebuilding and that may be where the oil smoke is coming from. If all the cylinders are within 20 psi and runs good, then it may be your valve guide seals are bad. You can replace them without pulling the heads. You can go to an auto parts store and buy a valve spring compressor that is used while the head is on the block. It has an air fitting that screws down into the spark plug hole and when filled with compressed air, holds the valves up while you remove the spring and replace the valve guide seal.

- Q:How to control the single acting pneumatic butterfly valve?
- Single acting pneumatic butterfly valve can be divided into gas open type and gas closed type, which is usually called "normally closed" and "normally open". This is very critical. The single feature pneumatic butterfly valve is the biggest feature of its spring reset function, when the loss of gas or sudden failure, you can automatically restore the original state. So it's important to open the air or air this time.
