This replacement valve body features a 3/8" x 1/2" SAE flare angle inlet configuration with external equalization, and is designed for use in the Alco HFK modular TXV system used across a wide range of air conditioning and refrigeration applications.

The HFK series is a balanced-port, take-apart thermostatic expansion valve system engineered for maximum serviceability and flexibility. The body kit is sold separately from the power element and cage, allowing technicians to replace only the worn component rather than the entire valve assembly. Capacities range from 1/4 to 5-1/2 tons nominal (R-22).
