I see a slotted screw adustment is this for pressure adjustment this thing is not that old?

[@IT-AEA]

this screw serves for venting - air access, pressure is not regulated in these designs

Ok how does sense pressure when ball valve closes. The messure current draw?

[@IT-AEA]

Inside is a spring that compressed and uncompressed under water pressure. Reed switch (magnets) that close or open the contacts on the board

@@IT-AEA are they field adustable For shutoff pressure?

[@IT-AEA]

Reed switch reacts to the spring. The pressure on the spring is created by the motor. Usually the pressure is 1.5 bar
