Upgrade your gas-powered air compressor with this all-in-one combination valve! Designed for compressors with 6.5HP engines or less, it includes a pilot valve, discharge unloader, and check valve in one unit. It features a 3/4\ compression top inlet for copper tubing and a 3/4\ male NPT outlet. The valve automatically unloads air when pressure gets high (the “OFF” setting, e.g., 125 PSI) and signals the engine to idle, then reloads when pressure drops (the “ON” setting, e.g., 95 PSI), saving fuel and reducing wear. The kit also includes a throttle control cable that connects the valve to your engine’s throttle arm, automating the engine speed based on air demand. Choose your desired PSI range and cable length at checkout. Made with brass and stainless steel parts for durability. Perfect for keeping your compressor running smoothly, efficiently, and longer. A professional-grade upgrade for DIYers and workshop owners alike!
