Giacomini R206C - Регулятор дифференциального давления

R206C balancing valves are differential pressure controllers that maintain constant pressure regardless the flow rate.‎ R206C is a straight-version linear controller and works without auxiliary power.‎ The nominal differential pressure can be continuously adjusted from 250 to 600 mbar.‎ The value for the setting can be read from the diagram.‎ The nominal set point is factory preset to a minimum.‎ A capillary (1000 mm) is included and should be connected to the circuit regulating valve in the flow.‎ Working temperature range: 2÷110 °C (-20÷110 °C with frost protection).‎ Maximum working pressure: 16 bar.‎ Maximum differential pressure: 2 bar.‎ Differential pressure range setting: 25÷60 kPa.‎ The valve is fitted in the return flow in any orientation.‎ The arrow on the valve body should align with the direction of flow.‎ It is recommended that an isolation valve is fitted both upstream and downstream of the differential pressure controller.‎ The valves must be installed for the correct application using clean fittings.‎ A strainer (R74A) should be fitted to prevent impurities.‎ Further info from manufacturer on R206C Giacomini
