Description
The Copeland 065623 is a straight-body, internally equalized Thermal Expansion Valve (TXV) engineered for reliable refrigerant metering in medium-temperature refrigeration applications. Designed for use with R12 and R134A refrigerants, this valve delivers precise superheat control to protect compressors and maximize system efficiency.
Key Features
- Refrigerant compatibility: R12 / R134A
- Nominal capacity: 1/4 Ton
- Temperature range: Medium temperature charge
- Equalization type: Internally equalized — ideal for systems with low pressure drop across the evaporator
- Body style: Straight body for straightforward inline installation
- Inlet connection: 1/4″ ODF sweat
- Outlet connection: 1/2″ ODF sweat
- Capillary tube length: 5 feet for flexible bulb placement
- Model number: AA 1/4 MC 5FT 1/4 x 1/2 ODF S/T
Product Overview
The internally equalized design of the Copeland 065623 TXV makes it well-suited for evaporators with minimal refrigerant-side pressure drop, ensuring accurate superheat regulation without the need for an external equalizer line. The 5-foot capillary tube provides ample reach for proper sensing bulb placement on the suction line, giving technicians flexibility during installation.
Applications
- Medium-temperature refrigeration systems
- R12 and R134A refrigerant circuits
- Small commercial and light commercial refrigeration equipment
- Evaporators with low pressure drop
Installation Notes
Connections are made via sweat (solder) fittings — 1/4″ ODF on the inlet and 1/2″ ODF on the outlet — for a secure, leak-free installation. Always follow refrigerant handling regulations and manufacturer guidelines when installing or servicing this valve.
