This rebuild kit is specifically engineered for the ASCO 8214 AC Series 2-way normally closed gas valves

This part is CCW rotation

ensuring 24V power at the R and C terminals and verifying the defrost thermostat (liquid line sensor) resistance is essential for proper diagnostics before swapping the control logic

For systems requiring emergency or auxiliary heat (2H/1C)

it automatically adjusts the refrigerant metered flow

Trane VAL10492 Expansion Valve 324846-701 This rebuild kit is specificallyThe Trane VAL10492 expansion valve, also identified by the industry designation BBIZE 6 GA B30, is a high precision thermostatic expansion valve (TXV) designed for consistent refrigerant flow control in high capacity air handling units and split systems. This externally equalized expansion valve is critical for maintaining the correct superheat across the evaporator coil, preventing liquid slugging while ensuring maximum heat transfer efficiency.
