Franke 19017657 Txv Expansion Valve Kit R290

Product Description

The FRANKE 19017657 is a thermostatic expansion valve (TXV) kit designed for use with R290 refrigerant in commercial foodservice refrigeration equipment. The kit includes a stainless steel valve body with a 1/4 inch inlet, 3/8 inch outlet, and a 30 inch capillary tube for bulb placement at the evaporator outlet. The TXV meters refrigerant flow into the evaporator based on superheat, maintaining consistent evaporator performance across varying load conditions. This is a direct OEM replacement part intended for installation by a licensed refrigeration technician familiar with R290 hydrocarbon refrigerant systems.

This valve kit is suited for commercial foodservice refrigeration systems that operate on R290 refrigerant, including reach-in coolers, undercounter units, and similar light commercial equipment manufactured by Franke Foodservice Systems. R290 systems are typically found in energy-efficient commercial applications where low global warming potential refrigerants are specified. Installation requires a technician certified to handle flammable hydrocarbon refrigerants in compliance with applicable local and national codes.

Key Features

• Rated for R290 hydrocarbon refrigerant — low GWP flammable refrigerant compatibility
• 1/4 inch inlet x 3/8 inch outlet connection sizing for direct OEM fitment
• 30 inch capillary tube for remote bulb placement at evaporator outlet
• Stainless steel valve body construction for corrosion resistance
• Direct replacement for Franke Foodservice refrigeration equipment

Compatibility

Designed as an OEM-style replacement TXV for Franke Foodservice refrigeration systems using R290 refrigerant. Refer to the equipment service manual to confirm fitment before installation.

Installation Notes

Installation must be performed by a technician licensed to handle flammable hydrocarbon refrigerants. Before replacing the TXV, recover all refrigerant from the system per applicable regulations — R290 is a flammable refrigerant and requires strict ignition source controls during service. Secure the remote bulb firmly to the suction line at the evaporator outlet and insulate it per standard practice to ensure accurate superheat sensing. After installation, leak-check all connections and verify superheat at startup before returning the system to service.
