Installazione di una valvola di controllo

Installation of a regulating valve should be carried out in accordance with the manufacturer's instructions and take into account the recommendations below:

• Pressure gauges should be installed before and after the valve.
• A strainer should be installed before the regulating valve.
• The valve body should not be subjected to torsion, tension, bending, or compression loads.
• The direction arrow on the body should match the direction of the medium flow at the installation site.
• To achieve optimal regulation, it is recommended to maintain a constant pressure drop at the valve.
• Flanged fittings in heating substations connected to heating networks may only be installed with the agreement of the heat supply organization.
• When installing a regulating valve on a horizontal pipeline, the electric actuator should be installed facing upwards, unless otherwise specified in the installation instructions.
• When installing on a pipeline carrying water with a temperature below 2°C, it is recommended to use a stem heater, and on a heat carrier above 130°C, a valve stem cooler.
• Different manufacturers provide different data, but on average, it is recommended to maintain straight sections of 5DN before and 10DN after the regulating valve. Otherwise, the characteristics of the valve may differ from those stated in the technical description.
