Abstract:
An embodiment relates to a manifold assembly, which comprises: a body in which a common chamber is formed; a first chemical flow channel connected to the common chamber and supplying a first chemical; a first valve for selectively opening or closing the first chemical flow channel; a second chemical flow channel connected to the common chamber and supplying a second chemical; a second valve for selectively opening or closing the second chemical flow channel; and a discharge flow channel connected to the common chamber and discharging the first or second chemical introduced into the common chamber out of the body. Therefore, the manifold assembly can have advantageous effects of: simplifying a process for discharging, cleaning, and sampling a chemical; and increasing stability and reliability.
