This listing is for a brand-new piloted unloader check valve combination with relief valve, designed as a high-quality aftermarket replacement for Ingersoll Rand part #56288756. Manufactured in the USA by Conrader, this solid brass valve offers durable, reliable performance and is commonly used on Ingersoll Rand twin tank gas-powered wheelbarrow-style air compressors.

The valve features a 1/2" inverted flare inlet on top (for connection to the main compressor line), and a 1/2" male NPT outlet on the bottom that threads directly into the air tank. It also includes a 1/8" female NPT port for adding a throttle control valve, if needed, and is factory preset to engage at 105 PSI and idle down at 145 PSI. A 325 PSI relief valve is built in for added safety.

Please note: The appearance may differ slightly from the original factory valve, but all connection points match OEM specifications. This upgraded version is proudly made in the USA and built for long-term performance.
