Sporlan 109837 Txv Assembly R-22 Half-ton Desuperheating

Product Description

The SPORLAN 109837 is a thermostatic expansion valve (TXV) assembly designed for desuperheating applications in R-22 refrigeration and air conditioning systems. Rated at half-ton capacity, this valve assembly regulates refrigerant flow into the evaporator by responding to suction line superheat, maintaining proper evaporator performance and protecting the compressor from liquid slugging. It is installed by licensed HVAC-R technicians as part of a complete refrigerant circuit service or new system commissioning.

This TXV assembly is suited for light-capacity R-22 systems where precise refrigerant metering and desuperheating control are required. Typical applications include small residential or commercial refrigeration circuits and specialty HVAC configurations that require active superheat management. Its half-ton rating makes it appropriate for compact evaporator coil assemblies in confined or low-load installations.

Key Features

• Designed for R-22 refrigerant systems
• Half-ton capacity rating for light-load evaporator circuits
• Desuperheating function provides active superheat control at the suction line
• TXV assembly format simplifies replacement and field installation
• OEM-style construction from Sporlan Valve Company

Compatibility

Designed as an OEM-style replacement TXV assembly for R-22 refrigerant systems requiring half-ton desuperheating valve service.

Installation Notes

Installation should be performed by a licensed HVAC-R technician certified to handle refrigerants under EPA Section 608 regulations. Recover all system refrigerant and ensure the system is fully depressurized before removing the existing valve or breaking any refrigerant line connections. Verify the bulb charge and sensing bulb placement match the system manufacturer requirements after installation. Do not braze near the valve body without proper heat shielding to avoid damaging internal valve components.
