Danfoss 034L0049 KVL 15 Crankcase Pressure Regulator

Designed to protect refrigeration compressors against excessive suction pressure, the Danfoss 034L0049 KVL 15 Crankcase Pressure Regulator enables a safe and stable circuit in which the compressor operating limits are not exceeded. With its copper body and robust construction, it provides long-lasting performance in professional refrigeration systems.

Protects the Compressor Against Overload

KVL series crankcase pressure regulators prevent overloading of the compressor motor by keeping the suction (crankcase) pressure below the set maximum value. They protect the compressor especially at start-up, after defrost or during periods of high suction pressure. This keeps the motor temperature under control and extends the service life of the system. Suitable for low-temperature applications and for commercial and industrial refrigeration installations.
