Description

EMERGENCY STEM SEALANT INJECTION standard feature allows Trunnion Mounted Ball Valve ’s stem housing to be adapted with a grease fitting to inject sealant during emergency scenarios, providing protection against unplanned spikes in operating conditions. This optional feature allows the valve’s end connections to be adapted with a grease fitting to inject sealant. This creates a positive seal in the case of seat leakage due to service impurities or unplanned spikes in operating conditions.
