Introduction:
Introduction of KVL Pressure-regulating Valve
Crankcase pressure regulator (CPR), is an outlet pressure reducing valve installed in the suction line (on a compressor suction inlet). Danfoss KVL crankcase regulators provided here are such a common accessory, setting with lower suction pressure to prevent the
refrigeration compressor’s motor from overloading.
What will cause compressors operating at heavy load conditions?
When the crankcase pressure rises above a predetermined level, the compressor is more likely to run in overloading condition. On refrigeration systems, this often occur during startup, or after/during a defrost cycle, or after a long period of standstill (a normal shutdown period). The Danfoss KVL crankcase pressure regulator, to a great extend, keeps the pressure in crankcase to a reasonable level, and further protect the compressor motor.
The CPR valves are adjustable. The suction pressure setting of the CPR must be low enough to protect the compressor. For more information on the standard factory pressure settings of Danfoss KVL 15, KVL 22 pressure-regulating valve, please mail to
