Description

Sullair Minimum Pressure Check Valve Repair Kit Replacement – 250018-456

Sullair Repair Kit Replacement (250018-456) is a factory-defined service kit used to repair compatible Sullair minimum pressure check valve assemblies on rotary screw air compressors.

This repair kit includes the internal service components required to restore proper operation of the minimum pressure check valve. The valve plays a critical role in maintaining minimum system pressure, supporting proper oil circulation, and preventing reverse flow during load and unload transitions.

Based on known applications, this repair kit is used to service minimum pressure check valves such as 02250129-374 and 02250109-817 on stationary units, including certain 100HP compressors. It is also used as a repair kit for the minimum pressure check valve 242405 on select Sullair portable compressors. Additional compatible applications may exist where the same internal valve design is used.

This replacement repair kit allows the existing valve body to be serviced rather than fully replaced and is commonly used during corrective maintenance when pressure control becomes inconsistent.
