About this item
- Dual Functionality Design: This innovative combo unit integrates both a pilot check valve and an unloader valve into a single compact assembly, streamlining your air compressor system while reducing the number of individual components needed for optimal operation
- Precise Pressure Range: Engineered to operate within the 145-175 PSI pressure range, this valve combo ensures reliable performance and automatic pressure regulation for gas-powered air compressor systems, maintaining consistent air delivery throughout your work cycle
- NG7 Standard Configuration: Features the industry-standard NG7 mounting pattern for seamless integration with compatible air compressor systems, allowing for straightforward installation and replacement without requiring extensive modifications to your existing setup
- Gas Compressor Compatibility: Specifically designed for gas-powered air compressor applications, this valve combo withstands the unique operating conditions and demands of gas engine-driven systems, ensuring long-lasting durability in demanding work environments
- Efficient Pressure Management: The integrated unloader valve automatically releases trapped air pressure during shutdown, reducing strain on the compressor motor during startup while the pilot check valve prevents backflow, protecting your system components and extending equipment lifespan
