Danfoss 034L0026 KVP12 Pressure Regulator

The Danfoss 034L0026 KVP12 Pressure Regulator is a robust evaporator pressure regulator designed specifically for commercial refrigeration systems requiring precise control of evaporating pressure. This KVP-12 model features a 1 1/8" ODF solder connection and is engineered to maintain a constant surface temperature on the evaporator by modulating the suction line flow. By effectively throttling the refrigerant gas to match the cooling load, it prevents evaporator freezing and provides critical protection for water chillers. Its high-grade stainless steel bellows ensure longevity and accurate response under varying thermal conditions. This valve is compatible with a wide range of HCFC, HFC, and HC refrigerants, including R22, R134a, R404A, and R407C. The integrated Schrader valve access port allows technicians to verify pressure settings and perform system diagnostics quickly. With a maximum working pressure of 260 psig and a broad operating range, this modulating pressure regulator is a standard for multi-evaporator systems powered by a single compressor rack.

• Precise Evaporator Control: Maintains consistent suction pressure to stabilize product temperatures and prevent coil icing.
• Durable Construction: Built with stainless steel bellows and a hermetic brazed design for leak-proof performance in high-vibration environments.
• Universal Compatibility: Approved for use with most common refrigerants and works effectively in systems with multiple evaporators.
• Easy Diagnostics: Features an integrated 1/4 in. Schrader valve for streamlined pressure testing and adjustment.
• Flexible Installation: Compact angle design allows for mounting in any position post-evaporator for optimized piping layouts.

How do I adjust the pressure setting on the KVP 12?
Remove the protective cap and turn the adjustment screw. Clockwise increases the evaporating pressure, while counter-clockwise decreases it. Use the Schrader port to verify the set point with a calibrated gauge.

Can this regulator be used with R290 or other flammable refrigerants?
Yes, the Danfoss KVP series is evaluated for use with Certain EX-range refrigerants like R290, R600, and R1270, provided the system design complies with local safety standards for flammable gases.

What is the maximum pressure this valve can handle during a leak test?
The unit is rated for a maximum test pressure of 286 psig (19.8 bar). Ensure the system pressure does not exceed this limit to avoid damaging the internal bellows.
