Danfoss 034L0144 KVC-22 Hot Gas Bypass Regulator 7/8" ODF

The Danfoss 034L0144 KVC-22 is a capacity regulator designed for adjusting compressor power to match actual evaporator load in commercial refrigeration and HVAC systems. This hot gas bypass regulator features 22mm (7/8") ODF solder connections on both inlet and outlet, providing reliable control of refrigerant flow in medium to large capacity systems.

Key Features:

• Regulation range: 0.2 to 6.0 bar (3 to 87 psig) for precise suction pressure control
• Kv value of 1.85 m³/h for efficient flow capacity
• Maximum working pressure: 28 bar for high-pressure applications
• Compatible with R134a, R22, R404A/R507, and R407C refrigerants
• Maximum proportional band of 2.0 bar (29 psi)
• Durable brass construction for long-lasting performance

By installing a bypass between the high and low pressure sides of a refrigeration system, the KVC sets a lower limit for compressor intake pressure by allowing hot gas to flow from the high-pressure side, preventing issues like compressor surge and maintaining system efficiency during low-load conditions. Ideal for walk-in coolers, display cases, and other commercial refrigeration applications requiring capacity modulation.
