Pressure Maintenance Valve for COLTRI Portable Compressors
This valve can be installed at the factory or easily added later, depending on your needs.
Main Features:
- Filtration Optimization: Prevents air from escaping the compressor until the internal pressure of the cartridge reaches a minimum of 150 bar.
- Pressure Retention: Maintains pressure in the system when the compressor is idle, thus improving air quality.
- Cartridge Protection: Prevents exposure of the filtration cartridge to ambient air when the compressor is not in use.
For optimal use, it is recommended to pair this valve with a filling valve such as the DRV232 (for 232 bar) or DRV300 (for 300 bar) model.
