Bohn efse-1-zp Txv R404A 1 Ton 3/8 Odf X 1/2 Odf

Product Description

The BOHN efse-1-zp is a thermostatic expansion valve (TXV) designed for use with R404A refrigerant in commercial refrigeration systems rated at 1 ton of cooling capacity. The valve meters refrigerant flow into the evaporator coil, maintaining the correct superheat level to protect the compressor and optimize system efficiency. With a 3/8-inch ODF inlet and 1/2-inch ODF outlet, this valve is sized for typical small commercial evaporator coil circuits. It is intended for installation by licensed refrigeration technicians and HVAC-R service professionals working on commercial refrigeration equipment.

This TXV is listed as a Heatcraft parts and accessories item, making it a direct-fit replacement for commercial refrigeration applications where R404A is the system refrigerant. Typical install scenarios include walk-in coolers, reach-in cases, and other commercial refrigeration units operating on R404A at 1-ton capacity. The ODF connection sizing is consistent with standard copper tubing used in these systems.

Key Features

• Rated for R404A refrigerant — common in commercial low- and medium-temperature refrigeration
• 1-ton capacity matches small commercial evaporator coil circuits
• 3/8-inch ODF inlet connection for standard liquid line tubing
• 1/2-inch ODF outlet connection for standard suction-side evaporator feed
• OEM-style replacement sourced through Heatcraft parts and accessories

Compatibility

Listed as a Heatcraft Commercial Appliance Parts and Accessories expansion valve kit for R404A systems at 1-ton capacity. Designed as an OEM-style replacement for commercial refrigeration evaporator coil assemblies using R404A refrigerant with 3/8-inch ODF inlet and 1/2-inch ODF outlet connections.

Installation Notes

Installation should be performed by a licensed HVAC-R technician certified to handle R404A refrigerant in accordance with EPA Section 608 regulations. Recover all system refrigerant and relieve system pressure before disconnecting the existing valve. ODF connections require proper brazing technique with nitrogen purge to prevent internal oxidation. After installation, leak-test all joints and verify superheat settings before returning the system to service.
