Danfoss 067B2771 Orifice

The Danfoss 067B2771 Orifice is a high-precision No. 8 capacity assembly engineered specifically for the Danfoss T2 and TE series thermostatic expansion valves. Designed for refrigeration and air conditioning systems, this orifice utilizes a fixed-flow architecture to ensure consistent refrigerant metering and superheat control. The 067B2771 is the direct replacement for 067B2175, providing a seamless field update for legacy systems without requiring a full valve body replacement. Its interchangeable orifice design allows technicians to tune system performance based on evaporator load requirements, making it a staple for R22, R134a, R404A, and R507 applications. Constructed with high-grade stainless steel components, it maintains metering accuracy under varying discharge pressures. For contractors managing Danfoss expansion valve troubleshooting, verifying the TXV orifice size is critical for preventing compressor slugging or evaporator starvation. This component ensures the valve maintains the precise mass flow rate required for commercial refrigeration stability.

• Universal Compatibility: Engineered for seamless integration with Danfoss TE 20, TE 55, and T2 valve bodies.
• Direct Retrofit: Functions as the updated technical equivalent for the obsolete 067B2175 model.
• Solder/Flare Versatility: Fits both flare and solder-type connections depending on the existing valve housing.
• Enhanced Mass Flow Control: No. 8 sizing optimized for specific tonnage ratings to prevent hunting.
• Field Serviceability: Allows for rapid cleaning or replacement without breaking the primary refrigerant line.

Can the 067B2771 be used as a replacement for 067B2175?
Yes, the 067B2771 is the official Danfoss direct replacement for the discontinued 067B2175 orifice, maintaining the same technical specifications and flow characteristics.

What refrigerants are compatible with this Danfoss No. 8 orifice?
This orifice is compatible with a wide range of common refrigerants including R22, R134a, R404A, R507, R407C, and R410A, provided the TEV power head and body are rated for that specific gas.

How do I determine if a No. 8 orifice is the correct size for my system?
Sizing depends on the evaporator capacity (kW or Tons) and the pressure drop across the valve. Refer to the Danfoss selection software or nominal capacity tables to match the No. 8 rating to your specific operating conditions.
