Sporlan 108813 Txv R-22 3/8x1/2 Inches Odf 30 Inches Ext Equalizer

Product Description

The SPORLAN 108813 is a thermostatic expansion valve (TXV) designed for use in refrigeration and air conditioning systems charged with R-22 refrigerant. The valve meters refrigerant flow into the evaporator based on superheat, maintaining efficient system operation under varying load conditions. It features a 3/8-inch inlet and 1/2-inch outlet in ODF (outside diameter fitting) configuration, with a 30-inch external equalizer line for accurate superheat sensing in longer evaporator circuits. HVAC/R technicians install this valve during new system builds and as a direct replacement in existing R-22 equipment.

This TXV is suited for residential and light commercial cooling and refrigeration applications where R-22 is the system refrigerant. The external equalizer design makes it appropriate for evaporators with a notable pressure drop across the coil, ensuring stable superheat control. It is typically found in split-system air conditioners, heat pumps, and refrigeration units where precise refrigerant metering is required for optimal efficiency and compressor protection.

Key Features

• 3/8-inch inlet x 1/2-inch outlet ODF connections for reliable brazed installation
• Rated for R-22 refrigerant systems
• 30-inch external equalizer capillary for accurate superheat control on longer coil circuits
• External equalizer design handles evaporators with higher internal pressure drop
• ODF fittings allow standard brazing with common HVAC/R tools and technique

Compatibility

Designed as an OEM-style replacement TXV for residential and light commercial R-22 refrigeration and air conditioning systems with ODF brazed connections.

Installation Notes

Installation should be performed by a licensed HVAC/R technician holding the appropriate EPA Section 608 certification for handling R-22 refrigerant. Recover all system refrigerant and isolate the system before removing the existing valve. Use a wet rag or heat sink on the valve body during brazing to protect internal components from heat damage. After installation, leak-check all connections and verify superheat is within the system manufacturer's specified range before returning the system to service.
