BPV – NPT threads
Proportional relief valve DN 15-32
Used in heating and cooling systems, the BPV proportional relief valve works quietly to ensure a minimum flow level in the pump while maintaining the desired supply temperature when operating at low loads.
Features & Benefits
Adjustable set-point
For accurate differential pressure control.
Shut-off function
For easy maintenance.
AMETAL®
Dezincification resistant alloy that guarantees a longer valve lifetime and lowers the risk of leakage.
