The SULLAIR 049905 Check Valve is an OEM replacement for Sullair rotary screw air compressors that prevents reverse airflow and maintains pressure in the compressed air circuit. It is an inline, unidirectional one-way valve designed for continuous-duty operation in industrial compressed air systems, compatible with SULLAIR stationary and portable compressors and constructed from cast iron or steel depending on the application. Commonly used in manufacturing plants, automotive facilities, machine shops, and food processing facilities, it supports repair, retrofit, or replacement of existing check valve assemblies and provides compressor protection and pressure retention.
