Danfoss 034L0046 Pressure Regulator 30067439-890 though some technical data sheetsThe Danfoss 034L0046 (KVL 28) Crankcase Pressure Regulator is a critical component for protecting compressor motors against overload during startup after long standstill periods or defrost cycles. Engineered with 1 1 8 inch ODF solder connections, this regulator maintains a maximum suction pressure, ensuring the motor is not lugging under high load conditions. The KVL 28 features a regulation range of 3 to 87 PSIG and comes with a factory setting of
