Commissioning notes The valves must be commissioned with the manual control knob or actuator correctly fitted. The Combi valves have to be open when flushing or pressure testing the system. Strong pressure impacts can damage closed Combi valves. Differential pressure Δpmax across the valve’s control path is not allowed to exceed 400 kPa. Manual control When turning the manual control knob in clockwise direction or operating the actuator, the valve opens. A reset spring closes the valve.
