Rolair 131CVQ2 Pilot Unloader Check Valve Module

131CVQ2 Pilot Unloader Check Valve Module by Rolair is a genuine OEM replacement that bundles the pilot unloader valve with its discharge check valve into a single serviceable unit for Rolair air compressors. It enables automatic unloading of the pump head when the system reaches the cut-out pressure, venting air back toward the tank to ease restart, while the integrated check valve maintains tank pressure after shutdown to prevent backflow. The part number 131CVQ2 is documented in Rolair's official service parts catalogs as a Valve, Pilot Unloader, confirming its role in the unloading and pressure-retention sequence within Rolair's unloading architecture. Replacing a failed or leaking unit with this module preserves correct cycling behavior and consistent pressure delivery, reducing unnecessary cycling and wear on the drive system. Designed to fit Rolair's unloading design, the module uses standard manifold connections found on Rolair units that originally employ the 131CVQ2 assembly, ensuring proper seal and compatibility with existing components. This description reflects the exact part number and function for buyers seeking an authentic Rolair repair part to restore original unloading performance.
