Description

The differential pressure regulator Elephant RDT is a normally open regulator, the principle of which is based on balancing the force of elastic deformation of the spring and the force created by the pressure difference of the working medium in the diaphragm chambers of the drive. The RDT direct-acting differential pressure regulator is designed to automatically maintain the differential pressure in the regulated section of the pipeline (between the supply and return pipelines) in the heating, hot water, ventilation circuits in the heating substations of heat supply facilities. The installation of a differential pressure regulator in the ITP prevents water hammer, helps to reduce noise effects on the control valve and increase its service life.
