MD, MS Manual Man ifold Sys tems
M anualm anifolds are designed to regulate
com pressed gases in high pressure cylinders
(up to 3,000 psig)and are idealform anifold
applications not requiring autom atic changeover
from the service to the secondary bank.The M D
Series duplex m anifold is designed form anual
changeoverof2 banks ofcylinders.The M S
series sim plex m anifold system allow s m anifolding
ofan unlim ited num berofcylinders in a single
bank.This system is often used as a high
pressure reserve forbulk,portable bulk and
gas generatorsystem s.
