York S1-029-26858-000 Chatleff Refrigeration Orifice 0.067

The York S1-029-26858-000 Chatleff Refrigerant Orifice 0.067 is a metering component used to regulate refrigerant flow into the evaporator coil. It is installed in compatible equipment where a fixed orifice is required to maintain proper pressure drop system performance. The orifice controls refrigerant metering within the expansion process, ensuring consistent distribution to the coil during heating and cooling operation. It plays a vital role in maintaining the system to balance and supporting efficient heat transfer across commercial HVAC systems applications. It is used during service replacement or system calibration procedures in field maintenance settings.
