Frese DPRV - Differential Pressure Relief Valve

Frese DPRV

Adjustable differential pressure relief valve

Frese DPRV can be installed in domestic and commercial heating and cooling systems.

The valve is an adjustable differential pressure relief valve (DPRV) that ensures the differential pressure across the load or circuit is not exceeded, and a minimum flow through the circuit will be maintained when the control valves are closing down.
