Sentinel - Degassing Valves - Brochure

Certain chemicals commonly used in metering and dosing applications are prone to outgassing. Other chemicals produce hazardous vapors that can escape the system at pump startup. A metering pump that has been off for a period of time can lose its prime and won’t pump fluid due to gas in the pump and discharge line. In all of these situations, gasses and vapors in a pumping system must be properly vented.
