Pressure retention valve DAV for monitoring third-party pressure

The pressure retention valve with float control opens at low water level considering the preset retention pressure. The main valve closes as soon as the max. water level in the tank is reached. The retention pressure is infinitely adjustable via the pilot valve between 2-16 bar. To avoid water hammers, the closing rate can be adjusted via the throttle check valve. The difference between minimum and maximum water level can be adjusted between 60 and 900 mm via the stops at the float rod.

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)
- Retention pressure and/or relieving pressure (P2 side)
- Holding pressure / back pressure
- Difference between min. and max. tank level
