Pressure reducing valve for electric actuation - closed at zero current

The pressure reducing valve reduces a variable inlet pressure to a constant outlet pressure, independent of varying flow rates. 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 (Order No. 1503)
- Open at zero current (Order No. 1504)

Use:
- Pressure reduction for feeding into the system
- Emergency feeding into a second system

Continuously adjustable outlet pressure between 1-15 bar
Minimum inlet pressure: 1 bar
Minimum pressure difference between inlet and outlet pressure: 1 bar

For rating, please specify the following:
- Flow (min., med., max.)
- Inlet pressure (P1 side)
- Outlet pressure (P2 side)
- Voltage (e.g. 24 V / 230 V)
- Type of power (alternating current / direct current)
- Type 1503 or 1504

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