4. Product introduction 

Brass bottom valve for water work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. The bodies (external shells) of most brass bottom valves are made of plastic or metal. An important concept in brass bottom check valves is the cracking pressure which is the minimum upstream pressure at which the valve will operate. Typically the brass bottom check valve is designed for and can therefore be specified for a specific cracking pressure.
