4. Deaerator water level pneumatic control valve (DALC): control requirements: provide flow to maintain the normal water level of the deaerator, increase the water temperature by adding steam to eliminate dissolved gases in water. Working condition: the flow in the startup phase is small, and the pressure difference is large. Under normal conditions, the flow is large, and the pressure difference is small. The working condition is similar to that of the water supply valve. Valve requirements: effective cavitation resistance at low flow.

The above is related to the top ten brands of pneumatic ball valves, which is the main reason why we choose the top ten brands of pneumatic ball valves. With pneumatic ball valves, people's life has become more and more convenient, and many factories have begun to use pneumatic ball valves. The normal use of pneumatic ball valve can only be guaranteed if its quality is up to standard, so try to choose from the top ten brands of pneumatic ball valve.
