A controller is required to control the ERV, as well as a power supply for the valve's stepper motor. The controller's input signals are readings from pressure and temperature sensors installed on the suction line. The evaporation pressure measured by the sensor corresponds to the evaporation temperature. The temperature signals indicate the superheat temperature of the refrigerant at the evaporator outlet. The EEV controller determines the superheat value as the difference between the superheat temperature and the evaporation temperature. For correct and safe operation, the superheat value must be between 7\u201310 \u00b0C. The controller compares the current superheat value with the set value and sends the appropriate control signal: to open the valve to reduce superheat. Expansion valve <strong>DPFAA1.8<\/strong> regulates the thermal power from 4.2 to 9.2 kW (depending on the refrigerant). <strong>For consultations, contact +37369104125.<\/strong> <strong>DPF1.8 expansion valve<\/strong> is intended for use in systems <a href=\"https:\/\/altal.md\/en\/heat-pump-altal\/\">reversible heat pumps<\/a>. Expansion valve <strong>DPFAA1.8<\/strong> automatically regulates the refrigerant flow and ensures the system operates in optimal conditions for rapid cooling or heating, precise temperature control and energy saving. Also, the Expansion Valve <strong>DPFAA1.8<\/strong> can be used, for example, to control the pressure in the suction line. Expansion valve <strong>DPFAA1.8<\/strong> allows bidirectional operation for managing refrigerant flow in heating or cooling mode.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Supapa_de_expansiune_DPFAA18_Caracteristici_tehnice\"><\/span><strong>Expansion valve DPFAA1.8.
