Danfoss 034L0097 Regulator

The Danfoss 034L0097 is a heavy-duty KVR 15 condensing pressure regulator designed to maintain stable head pressure in refrigeration and air conditioning systems during low ambient conditions. Built for field reliability, this 5/8" ODF solder valve prevents the condensing pressure from dropping too low, ensuring consistent liquid feed to the expansion valve and maintaining system efficiency. It features a robust hermetically hard-soldered construction that minimizes leak points, making it a staple for contractors managing air-cooled condensers in demanding environments.

This condensing pressure regulator operates within a precise adjustment range of 73 to 254 psig (5 to 17.5 bar), allowing for fine-tuned control of the high-side pressure relative to your specific refrigerant and load requirements. It includes an integrated vibration suppression damping device to protect the internal bellows from rapid pressure pulsations, significantly extending service life in high-vibration commercial applications. Compatible with a wide range of fluorinated refrigerants, including R-22, R-134a, R-404A, and R-507, the Danfoss KVR 15 is engineered for maximum durability with an MWP of 406 psig and a high-temperature threshold of 266°F.

• Head Pressure Control: Maintains consistent condensing pressure in air-cooled systems during cold weather to prevent liquid starvation at the TEV.
• Damping Mechanism: Built-in vibration suppression eliminates bellows fatigue caused by discharge gas pulsations.
• Easy Diagnostics: Features a dedicated 1/4" Schrader valve port for direct attachment of a pressure gauge for accurate setpoint verification.
• Hermetic Design: Hard-soldered ODF connections provide a secure, leak-free installation in the discharge or liquid line.
• High Temperature Tolerance: Rated for medium temperatures up to 266°F, suitable for high-discharge gas applications.

• Where should the KVR 15 be installed in the system? For optimal performance, the regulator is typically installed in the condensate line between the condenser and the receiver, or in the discharge line.
• Is this regulator compatible with modern HFO refrigerants? Yes, the KVR series is compatible with many HFO/HFC blends including R-448A, R-449A, and R-407C, provided the pressures stay within the 406 psig limit.
• Can I use this as a relief valve? While primarily a head pressure control, it can be utilized as a relief valve between the high and low-pressure sides in specific piping configurations.
