Differential pressure controller for closed heating or cooling system circuits. It helps protect control valves from pressure fluctuations and balances the systems to maintain a constant pressure difference. The controllers are characterized by high precision and compact dimensions, allowing for a wide range of connection possibilities.

The precision of the controller is ensured by a balanced cone inside the controller and a measuring nipple, which features a drainage option, facilitating the balancing processes. The controller allows for the setting of an exact desired balancing value. It also includes a shut-off function for easy installation and operation.
