Safety / pressure retention valve for electric actuation - closed at zero current

Description:
The relieving or retention pressure of the safety / pressure retention valve is infinitely adjustable via the pilot valve between 1,5-12 bar. Any excessive system pressure is relieved via the main valve opening quickly. The electric solenoid valve controls the filling and emptying of the pilot chamber. 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. 1403)
- Open at zero current (model no. 1404)

Use:
- Protection of a system against excess pressure (safety valve)
- Retention of the preset system pressure in the upstream pipe network (pressure retention valve)

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

For rating, please specify the following:
- Flow (max.)
- Inlet pressure (P1 side)
- Retention pressure and/or relieving pressure (P2 side)
- Holding pressure / back pressure
- Voltage (e.g. 24 V / 230 V)
- Type of power (alternating current / direct current)
- Type 1403 or 1404

Components:
1: main valve
2: ball valve
3: filter
4: orifice
5: throttle check valve
6: pilot valve
7: manometer with ball valve
8: optical position indicator with vent plug (option: electric position indicator, opening limiter)
9: electric solenoid valve
