Gate Valve
Historically flapper valves have been the primary choice for well isolation and safety devices used in well completion operations providing superior sealing and operating integrity over ball valves. For well intervention operations ball valves are generally preferred due to offering bi-directional pressure support despite having reduced sealing and operating functionality in comparison to flapper valves.
Benefits
Small ID to OD ratio for large bore valve deployment in marine riser or completion casing environments
Design uses proven sealing technology to provide a robust and reliable well containment valve
Enovate have developed En-Ter, a bi-directional pressure supporting flapper valve to offer well intervention systems the sealing and operating integrity found in well completions.
Advantages
Provides bi-directional pressure support to permit upper riser or completion to be used as a lubricator for introduction of well intervention tooling
High sealing integrity with increased tolerance towards high well flow and produced debris to improve reliability and performance
High sealing integrity with increased tolerance towards high well flow and produced debris to improve reliability and performance
Applications
Can be configured in fail open, fail-as-is or fail safe close operating modes and used as a safety or lubricator valve in well intervention and completion operations
