Danfoss 034L0029 Pressure Regulator

The Danfoss 034L0029 KVP15 Evaporator Pressure Regulator is a critical component for technicians managing suction pressure in commercial refrigeration and HVAC systems. Built with a 5/8" ODF solder connection, this valve ensures a constant evaporating pressure, preventing the evaporator from dropping below a set limit. It features a broad regulation range of 0 to 80 psig (0-5.5 bar) and comes with a factory setting of 29 psig. This KVP15 pressure regulator is engineered to handle demanding conditions with a maximum working pressure of 260 psig and a wide medium temperature range of -49°F to 266°F. Its high-flow design, boasting a Cv value of 2.9 gal/min, makes it ideal for evaporator pressure control in systems using R134a, R22, R404A, R407C, and R507. The hermetic construction and access port for gauge connection simplify diagnostic tasks, while the engraved flow direction ensures an accurate 1-way installation for maximum system stability.

• Precise Pressure Modulation: Maintains a constant evaporator pressure regardless of load variations to prevent coil freeze-up.
• High Refrigerant Versatility: Fully compatible with HCFC and non-flammable HFC refrigerants, including R134a and R404A.
• Superior Build Quality: Features stainless steel bellows and a hermetic design to minimize leak paths and withstand high vibration.
• System Protection: Effectively dampens pulsations in the suction line, protecting the compressor and improving overall system longevity.
• Easy Field Service: Integrated access port allows for quick pressure readings without breaking the line.

What is the maximum rated capacity for the KVP15?
The rated capacity varies by refrigerant; for example, it provides 4 kW (1.3 TR) for R22 and 2.8 kW (0.9 TR) for R134a at standard operating conditions.

Can this valve be used for oil-free applications?
Yes, the Danfoss 034L0029 is designed with lubricant compatibility suitable for oil-free environments and standard refrigeration oils.

Is the KVP15 adjustable in the field?
Absoluteley. While the factory setting is 29 psig, the regulator is fully adjustable within its 0 to 80 psig operating range to meet specific site requirements.
