Description
The York 025-40681-000 is an OEM thermostatic expansion valve (TEV) engineered to deliver precise refrigerant metering and optimal system efficiency in York refrigeration and air conditioning equipment. With 1-1/8″ inlet and 1-3/8″ outlet connections, this valve is sized for larger-capacity systems where accurate superheat control is critical to reliable, energy-efficient operation.
A thermostatic expansion valve regulates the flow of liquid refrigerant into the evaporator coil by responding to suction-line superheat conditions. This ensures the evaporator operates at peak capacity while protecting the compressor from liquid slugging — a key safeguard for system longevity and performance.
As a genuine York replacement part, the 025-40681-000 is designed to meet original equipment specifications, making it the trusted choice for service technicians and HVAC contractors performing warranty or out-of-warranty repairs on compatible York systems.
