DA 516

Differential pressure controller with adjustable set-point – DN 15-50

This compact differential pressure controller for heating and cooling systems is particularly effective in situations requiring high temperatures and/or pressure drop. DA 516 can be used both on the primary and secondary side in district heating and comfort cooling systems. Rust protection is assured thanks to the electrophoretic painted ductile iron body.

Features & Benefits

Inline design

Inline flow allows high pressure drops without noise.

Adjustable set-point

Delivers desired differential pressure ensuring accurate balancing.

Measuring point

Simplifies the balancing procedure, increases its accuracy and enables troubleshooting.
