Danfoss 034L0043 Valve
The Danfoss 034L0043 KVL 12 Crankcase Pressure Regulator is a critical mechanical valve designed to prevent compressor motor overload by limiting the suction pressure during and after defrost cycles or long standstill periods. Engineered with a 1/2" ODF solder connection, this KVL 12 regulator features a hermetic brazed construction and stainless steel bellows that provide accurate, adjustable pressure regulation regardless of inlet side variations. With a regulation range of 3 to 87 psig and a factory setting of 29 psig, it ensures that your refrigeration system remains within safe operating parameters. This suction line pressure regulator is compatible with a wide array of refrigerants, including R22, R134a, R404A, R407C, R507A, and R513A. Its compact angle design facilitates easy integration into existing pipework, making it a reliable choice for contractors maintaining commercial refrigeration systems and HVACR units.
Key Benefits:
- Prevents mechanical stress and compressor failure by capping maximum suction pressure at start-up.
- Features a pulsation damping design that extends the service life of internal components and reduces flow noise.
- High-temperature tolerance with a medium temperature range of -75°F to 266°F, suitable for diverse operating environments.
- High maximum working pressure (MWP) of 261 psig and a test pressure of 287 psig for robust system safety.
- Equipped with an equalization bellows, ensuring pressure regulation is only affected by the outlet pressure.
Common Questions:
Where should the KVL 12 be installed in the system?
The Danfoss KVL 12 must be installed in the suction line immediately ahead of the compressor to effectively limit the pressure entering the crankcase.
How do I adjust the pressure setpoint on this regulator?
Adjustments are made by removing the protective cap and turning the internal adjustment spindle. Turning the spindle clockwise increases the pressure setting, while counter-clockwise decreases it.
Is this valve compatible with modern low-GWP refrigerants?
Yes, the 034L0043 is rated for use with several HFC and HCFC refrigerants, including R513A and R448A/R449A, provided the system pressures align with the valve's technical specifications.
