Danfoss 032L1103 Valve R-407A ensuring proper impedance matching forThe Danfoss 032L1103 is a high capacity, servo operated piston solenoid valve from the proven EVR series, specifically the EVR 32 model. Engineered for demanding industrial and commercial HVACR applications, this normally closed (NC) valve features a 1 5 8 inch ODF solder connection, making it a standard choice for large scale liquid, suction, and hot gas lines. Constructed with a durable cast iron body, it supports a maximum working pressure (MWP) of
