The Nexus Valve Passim is a differential pressure control valve used in hydronic heating or cooling systems. By ensuring a constant differential pressure across motorized or static balancing valves, the Nexus Valve Passim valve provides the conditions necessary to achieve the desired flow distribution in a system. The Nexus Valve Passim valve eliminates also noise nuisance caused by high differential pressure across radiator thermostats, two way control valves or other components in a system. Min/Max Temperature: -20°C to 120°C. Max Pressure: 16 Bar.
