restrictor is required when used with low-volume output controllers

The 260 achieves this using characterized heating curves

The Trane MOD2688 Expansion Valve Module is a critical OEM replacement part designed for high-precision refrigerant flow control in heavy-duty commercial and industrial HVAC systems

designed to precision-fit the blower motor and squirrel cage fan to ensure accurate static pressure and directional airflow

which is usually reserved for rollout switches rather than primary high-limit safeties
