Description
The York 022-01887-000 Pressure Relief Valve regulates system, pressure by releasing excess buildup to prevent damage, to internal components. Featuring a 3/8 inch NPTF inlet with a 1/2 inch flare connection and a pressure rating of 300 PSI, it responds to pressure increases through a spring-loaded mechanism that opens at the set threshold and reseals once conditions normalize. Positioned within refrigerant or fluid lines in HVAC systems such as air conditioning and refrigeration units, it connects inline at designated relief points. This component supports safe pressure control, protects system integrity, and ensures reliable operation.
