Description
The Danfoss 034L0046 is a KVL28 series crankcase pressure regulator designed to protect refrigeration and air conditioning compressors from excessive suction pressure during start-up and pull-down conditions. By limiting the pressure entering the compressor crankcase, this regulator prevents motor overload and compressor damage — extending equipment service life and reducing costly downtime.
Key Features
- Danfoss KVL28 series crankcase pressure regulator
- 1-1/8″ solder (ODF) connection for secure, leak-free installation
- Protects compressors against high suction pressure overload during pull-down
- Automatic pressure-limiting action requires no external power source
- Robust construction engineered for long-term reliability in demanding refrigeration systems
- Compatible with a wide range of common refrigerants
- Compact design for ease of installation in tight mechanical spaces
Application
The KVL28 crankcase pressure regulator is ideal for use in commercial refrigeration systems, walk-in coolers, freezers, and air conditioning applications where compressor protection during high-load start-up conditions is critical. It is installed in the suction line between the evaporator and the compressor to throttle suction pressure and keep it within safe operating limits.
