Differential pressure controller with adjustable set-point
These differential pressure controllers for heating and cooling systems are particularly effective in situations requiring high temperatures and/or pressure drop. Also suitable for use on the secondary side in district heating and comfort cooling systems. Ductile iron body - painted with duasolid that offers good rust protection.
