5.FAQ
1. What is manual wafer butterfly valve?
A: 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?
A: 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.

Check the spring and plastic valve guide on top of the spring. I've seen these stick and the results are quite annoying, but once the spring moves up and down freely, so will the valve.
Q:what is the reason why non-return valves are installed in the discharge lines of the sea water pumps? ?
..?..non-return valves..? I will assume that your 'non-return valves', are what is also known as check valves. Check valves allows flow in one direction only. These are used wherever you need to prevent backflow into the system, or to maintain a charged circuit with fluid, until you choose to unload(depressurize ) it. Now, why are they used in discharged lines of salt water, basically to prevent backflow....reason not known, here , requires usage info.

Q:Explain how a valve works. What is the difference between in ATC, ATO, FO, FC, and FLP(Fail last position)?
When the individual ego is very high, directly relating itself to universal oneness is a difficult process, so he or she can get married and experience and grow with each other and than expand further.
