The on/off valve for electric actuation opens or closes the outlet area at the main valve. The valve can be used as an alternative to shut-off valves with electric actuator (observe closing times).
Filling and discharge of the pilot chamber is controlled via the solenoid valve. The main valve is opened at zero current and closed when energized. To avoid water hammers, the closing rate can be adjusted via the throttle check valve.
Version/position of main valve:
- Open at zero current (model no. 1704)
- Closed at zero current (model no. 1703)
Minimum inlet pressure: 1 bar
Minimum pressure difference between inlet and outlet pressure: 1 bar
For rating, please specify the following:
- Max. admissible flow rate
- Inlet pressure (P1 side)
- Holding pressure / back pressure (P2 side)
- Voltage (e.g. 24 V / 230 V)
- Type of power (alternating current / direct current)
- Type: 1704 or 1703
