The Danfoss 034G4211 Straight Electric Expansion Valve component is used in HVAC systems and it particularly used in refrigeration. This valve works based on controlling the flow of refrigerant into the evaporator to meet the desired cooling performance. It available in a connection size of 7/8” x 7/8” ODF which enables it to fit different piping arrangements. The valve uses an electric actuator which is controlled by the temperature and pressure sensors, so that the flow of the refrigerant can be adjusted by the current state of the system. The advantages of this expansion valve include increased system efficiency, lower energy use, and increased reliability, making it suitable for use in commercial HVAC systems, and heat pump systems.
