Hussmann 472727 Thermostatic Expansion Valve Adjustable

Product Description

The HUSSMANN 472727 is an adjustable thermostatic expansion valve (TXV) designed for use in commercial refrigeration systems. The 472727 meters refrigerant flow into the evaporator coil, maintaining the correct superheat level to protect the compressor and maximize system efficiency. Built to the FBSE-1/4-Z specification, this valve features a 1/4-inch connection size and an adjustable superheat setting, giving service technicians the ability to fine-tune refrigerant feed to match actual load conditions. It is intended for installation by licensed refrigeration or HVAC technicians familiar with commercial refrigeration circuits.

This valve is suited for commercial refrigeration applications where precise refrigerant metering is required. Typical installations include reach-in cases, walk-in coolers, display cases, and other commercial refrigeration equipment where Hussmann components are specified. The adjustable design accommodates varying load profiles and allows field calibration without replacing the valve.

Key Features

• Adjustable superheat setting for field calibration to actual system load
• FBSE-1/4-Z configuration with 1/4-inch connection size
• Designed for commercial refrigeration evaporator circuits
• OEM Hussmann part for direct replacement applications
• Meters refrigerant flow to protect compressor from liquid slugging

Compatibility

Designed as an OEM-style replacement thermostatic expansion valve for Hussmann commercial refrigeration equipment requiring the FBSE-1/4-Z adjustable valve specification.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician holding an EPA Section 608 certification. Recover all system refrigerant and relieve system pressure before removing the existing valve. Follow the equipment manufacturer's service literature for proper orientation, bulb placement, and superheat adjustment procedure. Do not braze near the valve body without protecting the valve internals from heat damage.
