they have two - four valves
yes lymph capillaries hav semilunar valves
A Plug Valve is a Globe Valve. Very generally speaking there are two major catagories of Industrial Process Control Valves, Sliding Stem and Rotary. Globe Bodies valves fall into the category of Sliding Stem Valves. Butterfly and Ball valves fall into the category of Rotary valves. However there are what is referred as Rotary Plug Valves, whereby a partial sphere has a shaft eccentrically mounted, that rotates into and out of a metal or composition seat acting as a plug. Most plug valves are sliding stem.
With check valves,selector valves,actuators,restricter valves and sequence valve,the most common hydraulic fluid is called skydrol,the fluid starts and the reservoir (tank) then it pass throw the EDP or the GDP (engine driven pump note:for flight use only) (generator driven pump note:for ground use only)and creates a flow which os converted into pressure,PSI (pressure per square inch)it reaches 3000 PSI and that force makes the landing gear go up and down
They are located internally in the transmission itself.
Sequence valves are used in aircraft having a retractable undercarriage because there is a certain sequence to the way things must be done. For example, before the landing gear can come down, the door on the undercarriage must be opened for it.
Please restate your question.

Plaiting can be done on a 15NB socket welded valves before hydro pressure testing. You would have to do blast cleaning and painting the pipe before this installation is done.Ê
It is a long process. Try contacting a local mechanic and have him tell you how.
Clean it internally and ensure that the corks are replaced when they wear and when you use it make sure you grease the slides and oil the valves.
The main difference between API 600 and API 503 valves is their port diameter. Also, the pressure testing between the two is different as well.
the chiltons manuals have very good instructions on how to set the valves
-tricuspid valve -pulmonary semilunar valve -mitral/bicuspid valve -aotic valve
The closing of the mitral and tricuspid valves produces the S1 sound, followed by the closing of the aortic and pulmonic valves, which produce the S2 sound. In sequence, it sounds like "lub-DUB, lub-DUB, lub-DUB".
