Danfoss 067B3352 TE 20 Thermostatic Expansion Valve Element for R404A/R507A, Externally Equalized

Description

The Danfoss 067B3352 is a thermostatic element for TE 20 expansion valves used with R404A and R507A refrigerants. Designed for externally equalized operation over a -40 to 50°F temperature range, it provides temperature-responsive control as part of a compatible refrigeration valve assembly.

Technical Specifications

Information About 067B3352

The 067B3352 is a replaceable element in the Danfoss TE 20 thermostatic expansion valve program. Its sensing bulb and 118-inch capillary tube transmit temperature changes to the element to support evaporator superheat regulation. External pressure equalization uses a 1/4-inch flare connection to reference evaporator outlet pressure. The brass assembly is intended for compatible TE 20 valve configurations and must be matched to the specified refrigerant and operating range.

Key Features:

• TE 20 Compatibility: Designed for use with compatible Danfoss TE 20 thermostatic expansion valve assemblies.
• Refrigerant Selection: Specified for R404A and R507A refrigeration systems.
• Thermostatic Operation: Responds to sensing bulb temperature changes to support refrigerant flow regulation.
• External Equalization: References evaporator outlet pressure through a separate equalization connection.
• Operating Range: Covers temperatures from -40 to 50°F (-40 to 10°C).
• Extended Capillary: Includes a 118-inch capillary tube for flexible sensing bulb placement.
• Flare Connection: Provides a 1/4-inch external pressure equalization connection.
• Brass Construction: Uses a brass body for the element assembly.
• Pressure Rating: Supports a maximum working pressure of 28 bar, listed as 400 psig.

The 067B3352 delivers the reliability and precision required for evaporator superheat regulation in compatible R404A and R507A refrigeration systems.
