Danfoss 034L0043 KVL 1/2" Crankcase Pressure Regulator

To protect the compressor against overload in refrigeration systems, the Danfoss 034L0043 KVL 1/2" Crankcase Pressure Regulator limits the pressure in the suction line, ensuring safe motor operation. With its copper body and red adjustment cap, it is a precisely adjustable solution that withstands field conditions.

Reliable Pressure Regulation for Compressor Protection

KVL series crankcase pressure regulators prevent the suction pressure from overloading the compressor motor at system start-up or under high load. By not allowing the crankcase pressure to rise above the preset value, they prevent the motor from drawing excessive current. With solder and flare connection options, they suit different types of installation and provide long-lasting performance in cold room and commercial refrigeration applications.
