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

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