Pressure relief and pressure retention valve DAV

The relieving or retention pressure of the safety / pressure retention valve is infinitely adjustable via the pilot valve between 2-12 bar. Any excessive system pressure is relieved via the main valve opening quickly. Closing is effected slowly to avoid water hammers.

Use:
- Protection of the system from overpressure (safety valve)
- Maintaining the preset mains system pressure in the upstream piping 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 (min., med., max.)
- Inlet pressure (P1 side)
- Retention pressure and/or relieving pressure (P2 side)
- Holding pressure / back pressure
