On/off valve for electric actuation - closed at zero current

Description:
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 closed at zero current and opened when energized. To avoid water hammers, the closing rate can be adjusted via the throttle check valve

Version/position of main valve:
- Closed at zero current (model no. 1703)
- Open at zero current (model no. 1704)

Minimum inlet pressure: 1 bar
Minimum pressure difference between inlet and outlet pressure: 1 bar

For rating, please specify the following:
- Max. 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: 1703 or 1704

Components:
1: main valve
2: ball valve
3: filter
4: throttle check valve
5: solenoid valve
6: manometer with ball valve
7: position indicator or opening limiter (option)

Material: Body parts: GJS-400, Hawle epoxy powder coated
Control line: stainless steel
Diaphragms, gaskets: EPDM
Solenoid valve: brass, stainless steel
Max. operating Pressure: See table
