Pump protection valve

The pump protection valve opens after pump start at a certain time delay after the solenoid valve has been activated. Thus the system pressure rises up to full pump operating pressure. On a pump stop the solenoid valve is released first so that the main valve closes slowly before the pump stops. In case of a power failure the pump protection valve closes via the integrated backflow prevention device. Electric actuation has to be provided by the customer.

Use:
- Prevention of water hammers in the pipeline system downstream of the pump.
- Protection of the pump from overload due to dry running.

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

For rating, please specify the following:
- Max. flow rate
- Static system pressure
- Pump pressure
- Voltage (e.g. 24 V / 230 V)
- Type of power (alternating current / direct current)

Components:
1: main valve
2: ball valve (A, B)
3: filter (A, B)
4: throttle check valve
5: solenoid valve
6: check valve(A, B)
7: incl. electric position indicator (see model no. 11998)
8: accessories (option)
