DAL 516

These compact differential pressure controllers for heating and cooling systems are particularly effective in situations requiring high temperatures and/or pressure drop. These valves are also suitable for use on the secondary side in district heating and comfort cooling systems. Rust protection is assured thanks to the electrophoretically painted ductile iron body.
