York 331-03999-602 EKF Stepper Valve Kit — 2-Compressor Systems
The York 331-03999-602 is an OEM EKF (Electronic Expansion Valve) Stepper Valve Kit engineered for York dual-compressor HVAC systems. This kit provides a precision-controlled electronic expansion valve assembly that uses a stepper motor to modulate refrigerant flow with accuracy, ensuring optimal system efficiency and reliable capacity control across both compressor circuits.
Product Overview
Electronic expansion valves (EXVs) replace traditional thermostatic expansion valves (TXVs) in modern commercial and residential HVAC equipment, offering tighter superheat control and faster response to changing load conditions. The stepper motor design allows the valve to move in precise incremental steps, enabling the system controller to maintain ideal refrigerant metering under varying operating conditions. This kit is designed as a direct OEM replacement for York equipment utilizing a 2-compressor configuration.
