Flow rate 1,000 … 6,450 l/min. Temperature range –10 … +60 °C. Operating pressure 4 … 18 bar.
The duration of the pressure build-up is adjusted using the restrictor attached to the valve cap. The output pressure p2 rises slowly in accordance with the restrictor setting. The main seat opens when the switchthrough pressure is reached. Pneumatically actuated soft-start valve for slowly pressurising and venting pneumatic installations (for use with on-off valves EM1 and EE). The drives advance slowly and reliably into the initial position. Sudden and erratic movements are avoided. Pressure switching approx. 50% of operating pressure. Adjustable switching time delay. Optional pressure sensor.Optional device variant EX4 for use in potentially explosive areas in
zones 1, 2, 21 and 22.
