Differential pressure controller 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 controllers are characterized by high precision and compact dimensions, allowing for a wide range of connection options. Installation into the system and commissioning is very easy and straightforward. The controller features a shut-off function that simplifies maintenance. The measuring nipple ensures high balancing accuracy.
