Duplomatic MSD3/50 modular sequence valve for NG6 (CETOP 3), adjustable from 10 to 70 bar.
Duplomatic direct-acting sequence valve in an NG6 (CETOP 3) modular plate, fitted without pipework underneath an ISO 4401-03 solenoid valve. Until the pressure in line P1 reaches the set value, the passage stays closed; when it does, the valve opens and feeds the next circuit. This is how a second actuator is made to work only after the first.
Adjustment is on the hexagon screw (17 mm spanner), and there is a 1/4" BSP gauge port to set the pressure. For higher ranges there are the MSD4/50 (30-140 bar) and MSD5/50 (50-280 bar).
