Role and use

The main valve is installed in the piping of the distribution line where the flow rate needs to be controlled to keep the predetermined flow rate unchanged, limit the excessive flow rate to a predetermined value, and reduce the upstream high pressure to the downstream low pressure. Even if the pressure upstream of the main valve changes, it will not affect the flow downstream of the main valve.
