Festo Solenoid actuated soft-start valves MS4-DE


  • Port G1/8, G1/4, G3/8
  • Flow rate 1000 ... 2000 l/min


The duration of the pressure build-up is adjusted with the aid of the enclosed restrictor to the valve cap. The output pressure p2 rises slowly in accordance with the restrictor setting. Only the air flow of the restrictor is available when the solenoid valve is not activated. The head office is only opened by activating the solenoid valve. When the solenoid valve is switched off, the main seat is closed and only the airflow from the flow control valve is available. The solenoid valve must remain on to vent a system as it increases the flow rate from 2 and 1 and reduces the discharge time.
