Valves: Allowable Leakage

Allowable Leakage vs. Zero Leakage vs. Bubble Tight

Valve leakage is one of the main issues in industrial processes. Different valve leakage standards are specified by different organizations. Valves go through pressure tests which determine if they provide allowable leakage, zero leakage, or are bubble tight. Allowable leakage: Some valves have an allowable leakage rate. These rates differ depending on what organization sets
