Return-temperature Control Valves

The Gestra self-acting return water temperature control valve range comprises the BW series for hot water and thermal oil systems and the CW series for condensers and cooling circuits. The valves operate without external sensors or auxiliary energy: a built-in fast-response thermal expansion regulator automatically adjusts the return flow according to the medium temperature. They are typically used for energy-saving optimization in industrial heating networks and heat exchange systems. Key selection parameters include the closing temperature, the medium handled, the nominal diameter (DN) and the nominal pressure (PN).
