Danfoss 034L0021 Pressure Regulator 30067439-890 A lockout is typically triggeredThe Danfoss 034L0021, technically designated as the KVP 12 evaporator pressure regulator, is a high precision mechanical valve designed for suctions side pressure modulation. For technicians managing multi evaporator systems on a single rack or compressor, this regulator is critical for maintaining a stable evaporating pressure regardless of load fluctuations. With its 1 2 inch flare connections and a robust Kv value of 2. 5 m h, it ensures reliable
