Gate Valve
Conventional BOP ram shear and seal technology is reliant on elastomer sealing elements that are susceptible to damage from velocity erosion and exposure to temperature and corrosive chemicals.
Benefits
Operating rational is that of a conventional gate valve to provide increased reliability and
performance
Optimised hydraulic actuator layout features provides the highest cutting force whilst minimises the required hydraulic operating volume
Optimised hydraulic actuator layout features provides the highest cutting force whilst minimises the required hydraulic operating volume
Provides in a single housing a replacement for all the shear and seal valves used in conventional LRP and light well intervention systems to give significant reductions in system height and weight
To provide a valve with substantially improved sealing integrity Enovate have developed En-Tegrity, a shear seal ram that provides a metal to metal seal.
Advantages
Efficient shear blade design concentrates shear force generated to offer significantly superior cutting performance to that provided from existing technology
Provides dual independent metal-to-metal well isolation barriers within a single housing to eliminate requirement for dual valves
Shear blade configuration ensures a solitary cutting action is initiated ensuring that no hub of the cut material remains in the well bore to interfere with the seal integrity or impede future well intervention operations

Applications
En-Tegrity is available in a range of sizes and configurations for both subsea and surface applications for well intervention and drilling operations
